You probably have heard about the latest Sigma 50mm f/1.4 ART lens (Click here) whose quality is almost as good as the $4,000 Zeiss Otus. This is just to say how Sigma is being “serious” with their new “ART” lens line.
It’s said “some” of them will have fast aperture. Well, according to one source Sigma will display new ART lenses with Micro Four Thirds mount at Photokina! And unlike the current MFT lenses, the 19mm (here at Amazon), 30mm (here at Amazon) and 60mm (here at Amazon) the sources said “some” of these lenses will have a fast aperture. The only not so good news is that also these new lenses will share the same lens design for all mirrorless mounts. A “dedicated” MFT lens design would have allowed Sigma to make them more compact because of the slightly smaller sensor size.
Now you can dream of some nice fast lens. What’s your wish?

I suppose Tamron is willing to make more primes or zooms that dedicated to M4/3 (proven by their 14-150mm), However Nobody will trust Sigma for making those glasses until they really reveal real product in stock. Anyway, many of you will want M4/3 equivalent of their C 17-70/2.8-4 – such a versatile standard zoom and still missing in M4/3 line-up.
Agreed, I have the 17-70 on my Canon 50D and would also like to have it on my E-M10.
A “dedicated” MFT lens design would have allowed Sigma to make them, IF AT ALL, THEN ONLY SLIGHTLY more compact because of the SLIGHTLY smaller sensor size – and the lower production figures per design would make them more expensive, and possibly not just slightly. So, as long as the lenses will be both good and affordable and as long as we’re talking about focal lengths which are by themselves desirable for MFT, too, I’m absolutely happy with whatever APS-C/MFT-combined designs Sigma will come up.
I’m sorry, but the lenses would be significantly smaller if designed for m4/3. There are plenty of examples of this out there when you compair equivalent lenses.
Like the Sony E PZ 16-50, 16/2.8 or 20/2.8? Just because there are existing APS-C lenses which are larger than existing equivalent MFT lenses, if these do exist (determining equivalence, did you account for aperture, by the way?), that doesn’t mean they have to be.
These Sony lenses are crap. That´s why they are so small.
Some of the smaller MFT lenses are crap, too, and some of the larger ones aren’t really good, either.
Try taking a 4×3 crop of any Sony lens even their worst with the Nex 7 and now Nex 6 you still end up with 21.3mp images and the difference in image quality is very clear. The 4×3 ratio is one of the main reasons why mFT lenses do so well. The 4×3 ratio uses almost 10% less of the extremes of the image circle than a 3×2 does making it much easier to achieve good corners if they all used a 4×3 ratio sensor there would be a very significant jump in the lens test results. It is my main reason for going mFT , though with its current 24mp sensor you can get a 21.3mp 4×3 image from an A6000 with much better lens results as long as you have a wide enough lens to accommodate the crop
Even those 16/2.8 of 20/2.8 are big compared to lenses like the Panasonic 14/2.5. They are even bigger as the Panasonic 20/1.7, which is also much better: http://www.thephoblographer.com/2010/09/05/lens-sharpness-test-sony-16mm-f2-8-vs-panasonic-20mm-f1-7/#.U7O17PVA_y4 . Besides that, it even captures more light then the Sony even compensating for the smaller m43 sensor.
Of course there are a lot of excellent lenses for the Sony mount, but in term of compactness of lenses(body not so much) it’s an easy win for m43.
120-300/2,8 with mft-mount would be nice.. or at least the 100-300/4..
My wishlist is 14mm f1.8, 19mm f1.8 and smth like 60mm or 75mm f1.8. Or maybe f1.4 all of them.
the by the 12mm f2, the 20mm f1.7 and the 75mm f1.8!
Or the 15mm f1.7.
The last thing the M4/3 system needs is MORE lens duplication!
I would really like Sigma to try their hand at pancakes, there are not many in m4/3, and they are damn useful.
Secondly I could do with a faster 14-42 as a GP lens.
good pancakes rely on manufacturing capabilities for good aspheres. This is my conclusion from the current designs at least. Hence the excellent ones from Panasonic.
Well, as I mentioned Sigma has heavily invested to narrow the tolerances of their machining tools. Of course they can’t do the impossible, but they can do inexpensive *and* outstanding lenses.
However because of curvature and short distance to flange it will always be difficult to produce fast lenses for Sigma, since they cannot use proprietary FW correction. That is also the reason why their lenses are bigger, even at 2.8.
9mm 2.0
12mm 1.4 or 14mm 1.4
It would be a dream come true… 😉
Yes you are right it’s just a dream. Problem with m43 is that Sigma and other manufacturers (Samyang for example) design their lenses for APS-C crowd.
So there will be no usefull focal range for us m43 users. It will be too long, weird and too big.
That’s why I’m still debating myself to swap system to either Fuji or Sony …
GAS GAS GAS…. haha..
Nope it’s not GAS !
It’s a completely different thing. m43 is becoming very expensive that’s just it. Especially anything which is within a range of wide and ultra wide. But mainly and finally competitors are becoming cheaper and better.
3 party lens companies are always cheaper that’s a fact. The only nice option with good focal ranges for m43 is Nokton. Sadly their lenses are fully manual focus only.
Do you still thing that it is called GAS ???
Anyway I always puchase used gear …
Basically there won’t be any wide lens, right? Then we’ll have some other “strange” focal lenght lenses. At this point I can only dream for a 120/150 mm f2. Or perhaps a 35-70mm equivalent f1.8
The excellent sigma 18-35 F1.8 would fulfill your 35-70 wish though its not small .There is the whopping sized Olympus 150mm FT F2 if you must have that focal length and aperture, I hear it does ok AF on the EM1.
There’s a mint condition 150mm f2 in my fav shop, it’s a beast of a lens, and you need to add the 4/3 adapter to use it. A smaller alternative would be great (at an interesting price, of course).
That 18-35 f1.8 was what I was thinking at. With a m43 mount I would consider to buy it.
Hi, would you mind sharing the location of the shop you’re talking about?
I’m under the impression that we might live quite close, seeing that you visit Venice so often…I might be able to go and evaluate the 150mm F2.
Thank you!
Ciao! Photomarket, a Mestre! Sei della zona?
Ciao, sono di Padova.
Per caso sei della zona di Treviso? Ho trovato un sito col tuo nome riferito a quella zona…
No, io sto in provincia di Vicenza ma spesso a Venezia: quello che hai trovato é un omonimo, spesso la cosa crea confusione.. Attualmente MarcoSartoriPhoto (con il ph) é il mio account su Flickr e 500px: mi si riconosce dalla stessa icona che si vede qua!
In effetti la cosa mi aveva confuso: mi sembrava una mano molto diversa!
Io capito a Vicenza quasi ogni settimana…se una volta tu volessi prendere un caffè e scambiare due idee su una passione comune mi farebbe piacere: sei uno dei pochi che pubblica dei post sensati su questo forum!!
Mandami un’email sul mio Flickr, magari ci si riesce ad incontrare!
Again we think the same! 🙂 Between 100mm and 180mm at f/2.8 or thereabouts would be good, especially if they make the lens macro capable. I’m currently thinking of getting the 4/3 version of the Sigma 150mm f/2.8 APO Macro, but I’ll need to test the AF performance first. The lens is quite big, it’s originally an APS-C design after all, but I can get it near mint at 350 euros. At that price I might get it anyway, even if the AF is not so fast.
Fast M4/3 prime lenses?
I’m very happy with my Voigtländers! What’s coming from them next?
From Sigma?
The question is: what sorts of lenses does the M4/3 system currently lack?
That’s where Sigma could make a reasonable addition/contribution to the M4/3 system.
I’d like to see some long lenses, a 105mm-ish macro or even a high quality 2x teleconverter.
m4/3 currently lacks a really sharp 35 mm equivalent AF lens, not the mediocre Zuiko 17/1.8
Look at Photozine review of the Oly 17/1.8… the sharpness graph bars are among the highiers I’ve seen.
I’d like to have the copy they have tested 🙂
I tried two copies and was disappointed with both. It’s not bad image quality, but when comparing photos throughout library taken with my various lenses, the 17mm stands out in a bad way. I’d spend $1000 for a super high quality reasonably sized m43 35mm equivalent lens. I don’t even care if it’s that fast.
The Oly 17mm gets a bad rap. It’s quite a good lens from what I’ve seen.
If you think it’s bad, blame the photographer, not the gear.
I’m certainly capable of taking some really lousy shots with my Voigtländers, or any other lens. 😉
“blame the photographer” Are you kidding Jeff? I am talking about low
sharpness. I use this lens very often and I like it (small, superb
built, fast AF, my favourite FL). But the resolution is really mediocre
especially in comparison with the 45/1.8 or the 25/1.4.
Don’t like this approach at all. The strength of MFT – among other things – does consist in the fact that our lenses can be as small as it possible, unlike e.g. Canon APS-C where most of good quality lenses are designed for the much larger FF sensor (they share the same mount).
I don’t mind, I mean its not like Sigma dictate what Panasonic and Olympus does. In the end, I actually rather have the choice.
If Sigma just puts a reverse tele converter (speed booster like) in there current art lenses and make them active mount on m43, they will sell like hot cakes!
I want a 50mm 1.0! with the same lens design of the DSRL system, and more light because it can be near at the sensor. Size and weight doesn’t matter. It would be a fantastic portraits lens.
17mm f1.4 with super fast AF.
Little cheaper same 50/1.4
17mm 1.4 19mm 1.8 or a 25mm 1.0
I wouldn’t mind if they would just release a Micro 4/3 version of the 18-35mm f1.8 if it meant autofocus and the same price as the current versions.
I have the 18-35 for my Nikon D7100 it is wonderful but it is pretty big , while 27-52.5mm effective range covers a few very useful focal lengths { 28,35,50} at a fast aperture and high quality . On my mFT gear it would be an effective 36-70mm not as useful though it of course that depends on what focal lengths you need
I have to work but that´s really serious stuff, so here we go:
7-10mm 2.8
12mm 1.8
17mm 1.4
25mm 1.4
43mm 1.4
But that´s never going to happen because Sigma is going to make these lenses for all mirrorless cameras. So they might design them for FF or APS-C at least. We won´t get fast wide angle lenses but some big and heavy ones with odd focal lengths for a lot of money.
Maybe a 24mm 1.4, 35mm 1.4, 50mm 1.4, 85mm 1.4, 100mm 2.0 etc is in the cards… or their APS-C equivalents.
My dream, a lens that is missing so musch in the lineup: A FAST UWA SHARP PRIME !!!! And I don’t want a APS-C lens with m43 mount, m43 means compact not half the glass being useless…
Let’s say:
– 8 or 9 mm
– At least f2.8, f2 would be better
– Distance scale (for night shooting where AF doesn’t work)
– Very sharp
– Compact and lightweight as possible while still being sharp
– metal construction
– Weathersealed is my dream lens !
I’m waiting to see the Kowa Prominar 8.5mm f2.8 that’s supposedly going to be released sometime this summer!
Has anyone tried converting a Samyang 8/2.8 from mirrorless APS-C to m43?
This would yield a sharp, light UWA, with much distortion, but not quite fisheye. The distortion may be OK in some applications, like astro and many landscapes, and otherwise can be corrected in post.
An 8/2.8 for Samsung NX would work, since the NX flange distance is slighly longer than that of m43.
my wishlist:
2.8 / 12mm
2.0 / 25mm
1.4 / 35mm
2.8 /135mm
I dont see that many gaps for M43 lenses -don’t get me wrong more choice is always better but some mounts like Sony E there is more gaps to fill; but will sigma go for FE/FF coverage then they will be probably big and heavy for M43. I am not too excited by this news.
OK my wish list:
Sigma’s 18-35 zoom F1.8 but with VR and M43 mount
18-105 EQ (9-52)VR power zoom F2.8 constant
60mm 1.4 VR prime
20mm 1.4 VR prime
12mm 1.4 VR prime
17mm f/1.4 !!
All the current AF lenses with around 17mm FL in MFT are crap.
Look at Photozine review of the Oly 17/1.8… the sharpness graph bars are among the highiers I’ve seen. Why everyone call it mediocre??
Groupthink.
Because a lot of people pretend the highest IQ, the highest cunstruction built quality, the smaller size at the lowest price. Back to the 17 f1.8 (that I own), I think that people should also try lenses, and not stick to some review. First review have been quite negative about that lens and its bad fame is still around. It has not the IQ of Voigty 17.5mm (I own that also), but it’s a lot better than the old f2.8 pancake version (I own that, again).
An other thing to consider. Its a $500 lens. A notch less actually.
At that price, I don’t exactly expect Zeiss cine quality.
Exactly, for that price the lens sould be much better/sharper. I like it anyway but still… once a time I am thinking about Pana 20/1.7 or the newbie 15/1.7
I totally agree, the 17mm f/1.8 is an underrated lens. Metal construction, great manual focus clutch, distance scale and a DoF scale. The sharpness is actually very good in the center and totally acceptable at the edges, even wide open. It’s a perfect match with the E-M10.
Agreed. I’ve been toying with the idea of getting a 17mm and a 45mm (I already have a 20mm) to augment my Voigtys for casual AF shooting.
Or maybe I’ll just go renegade and get a 12-40mm. 😉
Oly 17 & 45, can’t be happier. I’m from Argentina, Custom Taxes up to 85%. Custom officers think this lens are toys, no extra expenses. Good luck trying to pass an APC lens, those pays PRO taxes!!! I couldn’t choose a better system considering TCO (total cost of ownership)
Because the first review that came out said it was bad and people have kept that in mind ever since, even though there are plenty of other reviews that say the lens is good. Personally I love it. It is my favorite lens and photos come out great.
My copy is more in accordance with the sample they tested on DXOmark (7 MPx with EM5). the 45/1.8 is much better (9 MPx on EM5) and the 25/1.4 is perfect (11 MPx). And so my images from these lensens.
Your statement is crap 🙂 the 17/1.8 is fine, the 20/1.7 is very good, the 15/1.7 looks promising, even Sigma 19/2.8 is fine.
My bet…
I think Sigma will make something wider and longer than those 19 – 30 – 60mm lenses… So, 15mm f2.8 and 135mm f2.8. 17 – 70mm zoom (f2.8-4) would be a nice suprice, and could be made quite compact for mirrorless systems. A 12mm f2.8 can also be possible.
If they are in the same league as the 60mm f2.8, and reasonable prised, they’ll sell well. If they are like the 50mm f1.4A, I’ll by them all.
Keep some money for Schneider-Kreuznach, if they come any time?!
The SK 14mm f2 looks good… If I remember right, they had als a 60mm or 45mm macro coming. But they have been announced so long ago, that I don’t believe they’ll show up very soon. And I suppose anything coming from Sigma will be more reasonable priced.
I should have added to the end of my earlier comment, that if they (new lenses) are like the 50mm f1.4A and at the pricepoint of 60mm f2.8, I’ll by them all.
Anyway, if Schneider-Kreuznach will eventually make those lenses, the IQ and overall quality is good and the pricepoint right, I’m tempted. But in reality, I have about all lenses I really need…
Well it’s not nice that they use APS-C designs which will create too heavy lenses without real wide angles; but at least they don’t offer DSLR designs for mirrorless cameras, which saves some bulk and weight upfront.
Another idea: why don’t Fuji release their nice line-up of APSC lenses with M43 mounts -they would sell a lot more (maybe less cameras though)! OK not going to happen!
You know, Fujfilm is a 4/3 member… one can dream! At its current price I’d happily get the 56/1.2!
It would have been great if Fuji and Sigma released their own sensor designs, X-trans and Foveon, in M4/3 format, as they were former 4/3 members. Fuji is lost, but I still have a minimal hope, if any, for Sigma.
I don’t mind that the lenses are also made for APS-C mirrorless cameras. That ensures a reasonable price due to the higher production volume. While bigger, that also means when used on MFT, they should have better image quality in many ways when compared with those other cameras, ie less vignetting (and less exposure metering errors), less distortion, less edge softness, less CA, and less serious cats eye bokeh around the edges, and I think less effect from decentered elements,
Agreed. APSC designed lenses with M4/3 mounts drives the cost down. How much would those three current M4/3 Sigmas cost if they were native M4/3 designs?
As far as the lens size quibbles go, with our smaller M4/3 bodies, using larger lenses really isn’t a big deal. If I’m using a 400g GX7 vs. a 900g Nikon I can use a bigger lens and still have a reasonably compact set up because the body is so small.
I’d be even happy if sigma would make a m43 mount version of the 50 ART
(with autofocus coarse) the weight is worth the quality
I concur with you and yupp. BTW few know that under the new CEO Sigma has completely revamped its factory to avoid sample variation. So I would bet that there are no decentered elements anymore.
A reasonably sized UWA would be my own desire, fast not important.
Sounds good. The Sigma 19mm has become my main camera lens, even though it is the cheapest autofocus lens I have.
Yes , the concept of ART lenses designed for m43 have to be small . Moreover it have to be very fast as well .
Consider Art lenses are Sigma signature , anything have to be below F2.0 for a prime if Sigma really want to catch my eyes on it . A 150mm F2.0 & 7-14mm F2.8 would be sweet enough for m4/3 lovers to come to it .
I dunno… the Sigma 60mm 2.8 is a stellar lens. But yeah, I’d like to see f2 or below from them here soon as well.
It is stellar *because* it’s a 2.8 lens. Even at 2.0 it would be much softer.
It can’t be softer at 2.0, because it’s a 2.8 lens… At 2.0 it would be absolutely different design and you can not say how sharp it will be, because this lens doesn’t exist yet. And consider the fact that Olimpus, Panasonic Fuji etc offer very sharp wide open lenses from 1.2 to 1.8. Why Sigma can’t do it on f/2.0?
no its stellar because it is sharper at 2.8 than all m43’s lenses save the noct and oly 75.
The smaller 4×3 ratio sensor allows for easier designs. The 4×3 ratio uses less of the extremes of the image circle making corners less challenging.
A simple experiment take any image form any 3×2 ratio sensor using any lens and crop to a 4×3 ratio et voila you magically improve performance of even the worst lenses.
If they have to be APS-C designs, my bet is 12mm f2.8, 90mm f2.8 or 100mm f2.8. f2 or faster would be larger, heavier and more expensive and wouldn’t sell as well as the 19-30-60.
how about a 24mm f1.2 …good for both formats.
This is exciting if true, the Sigma 60mm is an amazing value. It would be nice to see 120mm F2 and 9mm F2.8 options become available.
Not an Art lens, but a 200/2.8 OS HSM would be amazing.
Not dedicated M43 + fast = big…
The gap in general: a true circular fisheye, say 4mm (equivalent of 8mm in full frame) for true 180° pictures, or lenses longer than 75mm
In fast lenses: there is currently a gap between 25 and 45 mm. A nice 35mm 1,4 or 1,7 would be an excellent portrait lenses
and please all genuine 4/3 lenses, no full frame lenses with a micro 4/3 fitting!
I’m waiting for someone to put out something like a Bigma 150-500 or similiar. Half the size, double the fun. Stopping at 300mm isn’t good enough.
i am waiting 2….
Yes ART on that itty bitty sensor, now I wonder: is ART better than PRO? Tough one…
I though one of the drawbacks for fuji and sony mirrorless was the larger lenses. Now it is awesome that sigma is doing this? Hmmm
M43 users take about small size like it was dogma. Most wouldn’t care if given the option to grab a cheaper or faster 1.4 with a bit of addition weight. It’s not the end of the world.
Would we like Sigma to make exclusive m43’s lenses so they are smaller? Sure! Barring that reality, would we like Sigma to make lenses that work with m4’3s even if they aren’t smaller? Sure! Choice is good… besides, when an m43 user needs a more compact system they can just grab one of the other 60+ small lenses and go.
Not this m43 user. If it is okey, buy a APS-c body. If this sells well, what is the incetive for any other company bar Panny and Oly to make special mFT lenses??
This is exciting news. They can’t just bang out a few 1.8’s for a bit less than the competition. Drop some 1.4’s please.
I’d like to see a wide angle at a reasonable price- like starting at 7-9mm. I’d also like to see a pro uwa zoom that doesn’t make me have to sell my kidney like Olympus’ recently announced zoom.
Cheap faster WR zooms please. If corners are awful on APS-C, so be it. 🙂
My list:
8mm f2.8 rectilinear
20mm f1.8 that fits the GM1 perfectly and has an aperture ring (obviously Sigma won’t make this, but it’s on my list)
42.5mm f1.0 that costs $1000
25mm f1.0 or 1.2
I’d even be curious to see how the ART 50mm performs on m4/3, though the lens is gigantic.
Essentially, I want Sigma to add to the lineup, not just duplicate the excellent Oly and Pany options…
Here is the GH4 with the 18-35mm attached.
http://www.kijiji.ca/v-view-image.html?adId=1000594522&image=0
If sigma would dare to mske the F1.8/12-70mm it would fantastic
I’d settle for 14-60/2. 🙂 If it’s APS, however, it won’t fit in my purse…
imagine 12-70mm with f1.8, you may have the 12mm, 14mm, 15mm , 17mm 19mm 20mm, 25mm, 35mm, 45mm, 50mm, 60mm and possible to replace the legend 75mm ALL IN ONE LENSE,.thats about 12 prime lenses covered with F1.8 or slower
Now THIS is seriously the most awesomest news so far this year!
Since neither Olympus nor Panasonic appear to be interested in giving us a complete set of FULLY WEATHERSEALED fast Pro lenses, my wish list for the Sigma m43 Art series would be:
12mm 1.4
17.5mm 1.4
25mm 1.2
45mm 1.2
67.5mm 1.4 (is that even possible??)
2.0 constant 10-35mm eq. wide angle zoom
1.8 constant 28-100mm eq. standard zoom
All Pro designed, standard 46mm filter sizes on all, except maybe 52mm or 58mm on the 45mm + 67.5mm. And FULLY WEATHERSEALED if possible! Wohoo. Well, it’s good to dream when it’s free. Hoho.
The size and cost of those lenses would mean that you would be better buying a FF camera and cheaper FF equivalent lenses.You would save money and for most lenses have less to carry. And this is from a diehard m43 user.
How would it be better when I will still gain significant size and weight advantages? I have the Canon 5D and 50mm 1.8. It’s a helluva lot heavier and bigger than my (new!) EM5 + 45mm 1.8. If I wanted 50mm POV I can get a Panasonic 20mm 1.7, which makes it even more compact.
Compare this: 5D + 50mm 1.4 vs EM5 + 25mm 1.4. Do you realise how much smaller the m43 kit is here? And that’s using Canon’s 50mm — try and use Sigma’s new Art 1.4 instead, and well, let’s stop talking about how it would be BETTER for me to buy FF and equivalent lenses instead, ey.
Another crazy comparison that I have in my bags:
(Canon 5D + 85mm 1.4 Planar) vs (EM5 + 50mm 1.4 Summilux).
No contest, my friend. Not even close. Why do I still keep the 5D? For the same reason I also have 2/3″, 1″ and 645 cameras — they all have their uses and looks.
Not all: compacts yay, ff yay, 645 yay, m43… Nay unless they cut those prices. It’s too easy to say “they are all good” – they aren’t.
How much do they pay you for every comment? I am curious to know.
You know, it really makes me wonder why your paymasters are scared shitless of m43. People like you speak volumes without you realising it.
Have you got a 25 mm F0.9 to compare to the plastic fantastic? No? I thought so.
You know, some people are not clear about equivalences yet.
Back again I see, el douchy. How was the stay at rehab this time around?
You really are dumb. For the sake of your argument, let’s compare optical lengths of the lenses, then. 50mm f1.8 vs 45mm f1.8. Close enough. 52mm filters on the Canon, 43mm on the Olympus. Let’s not even embarass you by comparing size and weight, shall we.
How about we compare the 60mm 2.8 Macro to the 60mm 2.8 Macro equivalent in FF? Again: you lose. Forget the sensors: remember you are talking about your stupid equivalences. So, optical vs optical. Bring a 42mm f1.2 FF lens and we’ll weigh it against the Panasonic. What? You got none? Oh, dear.
Now, Pro weathersealed body to Pro weathersealed body. 5D to EM1. Again, we’ll not embarass you by comparing size, weight and price, eh. Oh, how about we make it a bit fairer for you, then. 7D vs EM1, even though 7D isn’t fully weathersealed. Nope. Still embarassing for you, I’m afraid.
None of the Sigma primes are weather sealed, so highly doubt it.
Having these “big” lens “metaboned” by factory, would it work for M4/3?
Problem is those lenses will be ‘mirrorless’ APS-C lenses, ie, they won’t have the extra flange distance that DSLR lenses have compared to the m43 mount and thus won’t have the space to fit a speedbooster.
If price is right.
100mm macro please 🙂
Yes! Longer macro…Instant buy!
A 150mm would be even more suitable for me though.
I’d like to see a 12mm f/2 or faster, ideally a 1.4.
17.5 f/1.4.
25 f/1.4 or 1.2.
42.5 f/1.2 or 1.4.
67.5 f/1.8 or 1.4.
f/1.8 or f/2 12-35 or 12-40 fixed aperture zoom.
an alternative to the 7-14 f/2.8 at a lower price point.
All weather sealed and matte black of course.
shopping lists are just that. You don’t even know if it possible, but you pretend you have the money!
Go crawl back in your blog… Don’t you get it? no one is interested in your BS.
You don’t speak for others. Amalric is a valued member of this community and many of us respect his input. OTOH, your trolling is almost universally despised and you have been encouraged to leave many times.
What part of GTFO do you fail to understand?
BS Amalpric is a well known A-hole both here and on DPreview { when he is not banned } .He is an abusive racist with delusions of adequacy
LOL well said!!!
You are very rude, I bet you are all smarmy and soft offline. Mom did not spank you enough heh?
I agree Amalric is one of the smartest posters here tho. And I find him pretty dumb.
What’s wrong with dreaming?
Well, if they’re designed for APS, there are good chances that the corners are already excellent wide open. Not that much of a bad thing imo.
But the resolution might be lower…
I don’t think so. Yes, this does occur with FF lenses on APS too but that’s with older designs which are not so great on FF to begin with. I have faith in Sigma, at least in terms of sharpness. They (or their customer base) seems to be obsessed with it.
Oh, I didn’t mean that the quality will be lower because APS is a somehow inferior market. I meant that lenses designed for larger formats have, by necessity, lower resolution in absolute terms.
To get the same resolution of a 40 lp/mm lens on FF, you would need a 60 lp/mm lens on APS and 80 lp/mm lens on µ43; these will all get you about 1000 lp/image height. This is usually how things work out also because designing for larger image circle generally results in lower resolution, more aberration, etc. (Again, in absolute terms, not relative to image height; and because of technical and cost limitations, not because of lack of will.) Wider image circle also makes it more difficult to design lenses with lower f/ numbers, even with lower resolution requirements, although this is compensated for by image dynamic range. This is why large format lenses usually come up to f/4-5.6 and 10 lp/mm; medium formats to f/2.8 and 20 lp/mm; FF to f/1.4 and 40 lp/mm; and µ43 to f/1 and 80 lp/mm. In terms of resolution only, there is no inherent advantage to using larger or smaller image format. (Notice that the lens design advantage of µ43 vs FF is only one stop, where as dynamic range advantage of FF vs µ43 is two stops, so FF is still ahead on that, but only by one stop, not by two stops, as people usually argue. If you like deeper DOF and/or smaller equipment, you can see µ43’s image quality compromise is trivial.)
Now, what has been true is that FF lenses have had higher *relative* resolutions, largely because they target a more prestigious clientele, and because mirrorless APS and µ43 lens systems are still building up their stable. Still, even the best FF lenses have “absolute” resolutions inferior to mediocre µ43 lenses because of the size-quality compromise. This is why it’s important to have a lens designed for the format.
“Now you can dream of some nice fast lens. What’s your wish?”
now we have plenty of 30 mm, 25 mm, 50 mm, 7,5 mm, 12 mm, 45 mm, 44 mm, 43 mm, 42 mm, 41,5 mm, when have we a 500 mm or a 600 mm or a 2x teleconverter ?

42.5mm f1.2 non stabilized would be nice
Yeah, basically a non-IS Nocticron made by Olympus with the Olympus look would be awesome… And cheaper than the existing Nocticron.
Too bad that won’t happen. I’d probably drop the $1200 it would cost.
My WISH is a m4/3 lens. not an A{S_c lens with a mFT fiting. Keep it. I’ll never buy it. If people start buying these lenses, why not buy a APS_c body too?
APS-C lenses are not bigger, they just use longer FL’S that make them ‘bigger’, it is the actual FL and actual aperture that dictate the size. So on m43’s they won’t be ‘bigger’ than native lenses, just longer FL.
Oh and my wish for lenses? This line up in true mFT format:
12,5-37,5 OIS WS/DS +/- f2,5 to f3,2
37,5-125 OIS WS/DS +/- F2.8 to f3,5
125-300 OIS WS/DS +/- F3,2 to f4,0
250- 400 OIS WS?DS +/- f4,0 to f5,6
10 mm f2 prime
80 mm f4 macro
400 mm F4
12,5-125 F2,8- f4 WS/DS with zoombutton for video
All lenses must work well with DFD and OSPDAF.
A really nice aspect of the m43 eco system are the affordable, powerful prime lenses such as the well-known Panasonic 20mm or the Olympus 45mm. Even as an almost daily GX7 user I am not sure if I wanted to sink more money into much larger, heavier and, of course, significantly more expensive glass.
The Nocticron, for instance, is an impressive product but given its size / weight one might opt for the A6000 + 50mm / F1.8 bundle instead. From a technical point of view the differences would be minor (I suppose the A6000’s achievable resolution would be higher), from a practical point of view the kits would be more or less the same size and price-wise the 50mm is just 19% (!) of the Nocticron.
Conclusions:
– m43 is particularly great in the prime lens space (I am not impressed with the somewhat ‘fast’ zooms that have been made available in the past 18 months or so)
– using a non-optimized lens on m43 is challenging since the size is usually unattractive
– it should be fairly easy to produce fast zooms in the APS-C domain that surpass m43 zooms but manufacturers seem hesitant to offer fast, large zooms since they would be too heavy.
Well, the zooms are necessary because we old 43 shooters are used to having high quality Olympus zooms. The best or close to in the business back then. Only let down by the sensor tech in the cameras. Since they abandoned us by saying they will move us to a m43 system instead, they have to keep that tradition alive, now that they have the EM1 body. High time they introduced a new entry level Pro body to replace the EM5, I feel.
Since Panasonic didn’t really do it last time, just let Sigma take the 20mm 1.7 and turn it into a super fast AF 20mm 1.7 mark III.
I say why stop at f1.7 when you should be going for f1.4. Sigma’s Art line is premium on other sensors, they should keep that differentiation from the existing f2.8 range.
Existing f2.8 lenses ARE Art series lenses.
Wouldn’t mind a 1.4 of course, if the iq can match the existing 20mm 1.7 and if it doesn’t turn out too hefty.
Surely the more the merrier.. choice is a good thing, and with what Sigma has been cranking out in their new ranges. This can only be a good thing.
It would be awesome if when making mirrorless versions of DSLR lenses, sigma designed them to take a focal reducer in the same manner as a drop in filter.
Wait… for m43 only?! Is sigma ditching FujiX and E-Mount?!
Sigma should make a 10 1.4–the ultimate night photography lens!
