We have two new A-mount lenses from Sigma:
Sigma 50mm f/1.4 DG HSM ART lens specs at Sigma Photo. (Note: Sigma missed to add A-mount as an option on the link I gave you. But it’s just an error. Press releases do confirm there will be an A-mount. source: Sigma Japan, ePhotozine or Dpreview)
Sigma 18-200mm F3.5-6.3 DC Macro OS HSM at Sigma Photo.
Particularly the 50mm f/1.4 Full Frame lens sounds intriguing. It has a completely new design (retro focus with 13 elements and 8 groups) and if this lens performs as good as expected it could get surprisingly close to the [shoplink 23842 ebay]Zeiss Otus 50mm f/1.4[/shoplink] performance. There are no pricing info and no image samples yet. So we will have to wait a bit to see if this lens can fulfill our hopes!

Hmm…the 50 does look quite interesting!!
Well I think anyone who bought the overpriced Zeiss ZA SSM is going to feel a little silly right about now 😉
It’s kinda overpriced, yes. Specially if I consider the Manual Focus only, non-weathersealed Zeiss 50mm f/1.4 for Canon and Nikon mounts as a reference. But I don’t feel silly at all. I have a weathersealed lens that performs very good on my a850 right now from some time ago. And from what I have read, the new Sigma isn’t sealed at all (Yes, weathersealing is a must to me right now).
Now, if we take the 35mm ART as reference, I feel curious about this new 50mm ART. If it aims towards Otus-like performance, hope it doesn’t exceed the 1500USD mark (And I’m sure they will offer it for way less than 1500USD).
What’s Sigma’s and Sony’s problem with weather sealing their lenses. Every time the weather turns on me I find myself using the A77 with the SAL1650, or A850 with the 70200G2. Especially the Zeiss lenses which should be bullet proof for the price they’re asking for them.
This is an interesting lens as it is more lightweight than the rest of the recently published high-end 50mm lenses. I hope the AF speed is substantially improved over the Art 35mm lens.
Me too. I purchased two 35mm Art lenses and returned them both due to painfully slow AF. In some instances in low light it even refused to focus, where the Sony/Minolta lens or my old Canon L would have.
I curse Sigma on a daily basis considering how incredible all other aspects of that lens are, price included.
The weight of this lens is tba. the dimensions look quite huge compared to the Zeiss 50/1,4 SSM. it could weight 700-800 grams, I would guess. If the bokeh is better than the zeiss and the pricing is at around 500 Euros this could be a winner still.
Better bokhe than the zeiss for only 500$? keep dreaming.
500 Euros?? The Sigma 35 is £650 already; no reason to think this will be any cheaper…
50mm F1.4 lenses are far less expensive than the 35mm F1.4 options from Canon/Nikon etc.
Don’t compare this lens to a normal 50mm f/1.4, compare this lens to the Otus because that’s the only other lens in this category.
How do you know that without seeing on sample
Picture?
It is a Sigma lens in their “ART” line up, the excellent 35mm F1.4 which I already own is around the £640 mark. There is no doubt that a 35mm F1.4 is more difficult and therefore more expensive to design and manufacture than a 50mm.In every lens range that has both be it from Leica , Nikon or whoever, the 35mm F1.4 is without fail more expensive than the 50mm F1.4 sometimes considerably so. I will be very surprised if this Sigma 50mm F1.4 is any more expensive than their 35mm F1.4. Though I have certainly been surprised before 🙂
They’d sell more in E-mount!
I agree totally..
Sigma should start making 3 mount lenses again
I cannot believe I have to say this again!… IT WONT FOCUS WELL ON E-MOUNT, period. It would be a complete waste of time making it in E-Mount. Get it? Got it? Good.
…says the person with absolutely no basis of fact or experience for this statement.
It doesn’t appear to have stepper motors. It’s designed for PDAF systems.
This leads to the logical conclusion that it won’t perform well in terms of AF on a CDAF or hybrid CDAF system, since this olds true for all existing lenses fitting the above description. And for good technical reasons.
That is not a logical conclusion, because the logic includes too many assumptions that conflict with reality.
The old, screw-drive, buzzy ZA 85mm f/1.4 and the completely screwy 28-75mm f/2.8 both focus without any issues – accurately and without undue delay on the A7r with LA-E4. This is based on real shooting and experience.
The Sigma 35/1.4 focus beautifully on the A7r. I own it. Use it.
Unless you’re shooting BIF or maybe some sports – missed shots would be user error, not your gear.
Yes, with the LAEA4 all screwy, SSM and SAM lenses will work because it contains a PDAF module. Most DSLR lenses will not work well at all on native CDAF based cameras without any kind of additional PDAF system. Try the LAEA3 with the same lenses (SSM and SAM only), and you will understand what I mean.
Got it. The pellet with the poison’s is in the vessel with the pestle. The chalice from the palace has the brew that is true.
No one (else) will get that reference, but I am now laughing to myself thinking about it. Thanks.
Anyway, still a mystery to me why the on-sensor PDAF of the A7 is not good (I have it, it’s not good). Can anyone explain technically why PDAF doesn’t work well on-sensor? Why doesn’t it work better that tradition PDAF (which I would assume it should)?
Size of sensors.
Full size PDAF gathers light from a large area, OSPDAF is only pixel-based. It’ll always be inferior to real PDAF.
(of course assuming both are on a same technology level)
(and by “Size of sensors.” I mean sensors used in autofocus module itself)
No Reply button for LenIsAll’s comments, so replying to myself, like one hand clapping:
Phase detection sensors are just imaging sensors – no magic, just imaging sensors. If amount of light matters so much, a mirror-less camera should do better, no, since the light path to the PDAF sensor is clear (no translucent mirrors and other mirrors). And with the huge improvements in imaging sensors over the past decade (or more), I would have assumed that what worked in an EOS 3, for instance, could be crushed by much smaller sensors today (especially paired with much faster processing). So, I am not buying your explanation, unless you can tell me why size still matters for PDAF sensor when it matters much less so for imaging sensors these days. (In case I haven’t totally tipped my hand, I will state that I suspect this is more likely a read-out issue).
Its designed for the A9. Oh and why would anyone want a heavy lens for camera with no stabilization platform? Do you intend on keeping your camera on a monopod or tripod??
Sony keeps Sigma, informed about the FF mirror-less A-Mounts developments. Its the reason they haven’t produced a FE lens. The mirror less A-Mount will likely outsell the A7 series by at least 3 to 1.
I’ve been told the mirror-less a-mount FF cameras are launching sooner than any of us expect. Weeks as opposed to months. They stopped production of the A99 in Nov to ramp up production of its successor.
Sony wants its cameras to be completely mirror less by the end of the year.
what would be the benefit of mirrorless a-mount apart from low light performance? why wild they start selling so well all of a sudden?
Sony is a mirror-less camera manufacturer. The SLTs are the exception to the rule
Sony is a recognized leader in the mirror-less segment. Its NEX 3, 5, and A7 are solid sellers that are profitable, and likely sell for healthy margins, as opposed to the consumer DSLRs with wafer thin margins.
Mirror-less is the future of interchangeable lens cameras whether we want to believe it or not. Sony hasn’t been a strong player in the DSLR market, and their share has only ever been marginal at best.
The mirror-less market is growing, and the DSLR segment is in rapid decline. Sony isn’t stupid and they know some fights are best avoided.
It is in Sony’s interest to move the A-Mount bodies to mirror less where they’ll likely sell more of them, for higher margins, growing their user base, and avoid losing/alienating their current customers (Who spend thousands of dollars yearly, as opposed to hundreds).
Because in the end its all about the money.
No it wouldn’t.
It’s you vs Sigma sales statistics, and these tell that sales of Sigma lenses on E-mount are horrible.
Oh, and remind me how many nexes would fit inside of that lens? 5? 6? more?
E-Mounts owners are people who have migrated up from point and shoot cameras, and smart phones. They generally don’t buy many additional lenses.
A-Mount users are the opposite, buying plenty of lenses, most of them are worth more than an A5000.
A single 24-70mm is worth more than three A5000s, and generates five times the profit.
Sooo… It probably won’t come in e mount, will it ?<
No – latest from sigma is they have no plans to make FE lenses…
They’ll probably start building them once when the FE user base is large enough. I’d estimate by the end of 2016.
Are you sure this will be available in A mount from what I have read online it will only be available for Sigma, Canon & Nikon mounts?
dpreview states it’s also available for Sony A-mount.
No A Mount. So why is this Lens on SonyAlpha rumors then Corresponding Mounts

It’s an error on their site. All other sites (Sigma Japan and so) confirm there will be an A-mount version.
Go, and Google Sigma Japan, please.
I have the previous version, and have found it to be excellent (at least on APS-C). However, it is very large and heavy, so might look a bit out of proportion on an A7/A7r, especially with the required adapter. This version will be similar.
If a native E mount version was produced, it would be essentially the same size as the lens+adapter unless it was optically redesigned to make use of the shorter lens register (which could well adversely impact edge performance).
I was, of course, referring to the 50mm lens.
I had it as well and used it on a nex-6 and A77. From what I see of the zeiss 50mm . The zeiss is not that much better at all. Some say the zeiss is sharper wide open but I don’t really agree with that. I had a used tested copy I got for 300.00 and it was sharp as hell. From what I read the lens actually performs better on a full frame. I may get it again and test it out on my A7 and rent the zeiss and see what the real difference is.
I still use the 50F14, and really didn’t see any reason to upgrade. This Sigma is going to cost three times as much, for a marginal increase in performance. Its not even weather sealed.
I’d rather buy a 135mm SFT for the difference.
With a 77mm filter I’m guessing that’s about the size of the Zeiss 135mm f1.8!
But if the size produces the performance I might still be tempted.
Why? You could probably buy a second hand 85mm Zeiss, and 50mm Sony for the price of this lens.
no you couldn’t
http://www.keh.com
but the price! a new Sony 50 AND a used zeiss 85? the sigma won’t be that expensive.
wait a minute, are you comparing to the zeiss 50 1.4?
No just the SAL50F14 the regular Sony one.
Its light weight well built, and cheap enough. Its IQ is good enough for most jobs, and the difference between the two is marginal.
Or you could buy the Minolta 85mm G (d) instead of the Zeiss for $300.00 less. Pictures taken with it just look nicer, especially flesh tones.
and you’d still have money to spare.
Andrea stated “There are no pricing info” and I didn’t find any elsewhere.
If Sigma can repeat the 35mm f1.4 results, they could produce a lens that matches almost anything for performance and yet is still reasonably priced.
So it could outperform the Sony/Zeiss 50mm f1.4, whilst still being considerable cheaper – if that’s the case I can live with it being bigger.
But all early days and guesswork at the moment – last year I wouldn’t have held out any hope, but Sigma have been producing some amazing optics just recently.
Its not weather sealed and the build quality will likely be inferior to the Zeiss. Its a fair weather lens. I’d rather wait and buy a second hand Zeiss 50mm.

Their press release clearly indicates Sony Alpha
..and the Sigma site clearly states that it does not! So what?
Press release is correct, sigma website is wrong. Their site is as poorly managed as Sony website with plenty of mistakes all over the place.
Press releases are put out for immediate announcements, many companies are slow to formally update their web site.
It’s weight is 470g, length 100mm, diameter 85(around front element), not heavy at all considering the total number of glass elements and thus not quite tiny. It will come in A mount, the only questions is when, how long after Nikon, Canon and Sigma…and it will cost more then the current 50 but much less than the Zeiss!? By the way, anyone interested in a 50mm 1.4 ZA!? 😛
Anyone interested in buying sigma 50 in a year? Zeiss ZA is already on my camera.
I’ll take your Zeiss ZA. Cracks me up you think this will magically make your shots better!
Just joking with the ZA…superb images, superb autofocus…for one who hasn’t already spent that great deal of cash on buying the Zeiss, this Sigma if broven to have IQ on the same level and a trusty autofocus, would be a very interesting competitior in the 50mm A mount segement given it would probably cost around half of what i’ve payed for mine(50 ZA). If i was into buyuing a 50 at this moment it would be definately worth considering. The only question is wether it will take long for Sigma to release the A mount and for us to be patient enough. Reviews from Nikon(usually gets out first)versions will be available soon as an indicative to IQ and autofocus accuracy.
The OTUS IQ equivalent discussion is plane nonsense. Don’t know where it started in the first place…also the E mount discussion has no serious ground. Just read the press release from DPREVIEW or others. This is not aimed at mirrorless.
It started because this sigma 50 ART has 13 lenses in 8 groups, close to OTUS in lens design complexity.
I’m an owner of the SAL50Z too and agree, this would have been tempting to consider as an alternative. But my Zeiss 50 is the sharpest lens I own, and that includes the Sigma 35, and the Zeiss 50 and 135.
The comparison with the Otus lens is just fantasy though. Zeiss made no compromises in size, weight and cost to create the best lens possible. However, at some point, return on investment might make the Sigma offering very attractive, but just like that Pagani costs a lot more than the Corvette for only marginally better performance, it’s still a Pagani and a Corvette is still a Chevrolet. Zeiss will always be Zeiss and Sigma will always be Sigma.
Yes, no one will ever be more than they are right now. Good logic.
The press release quoted by dpreview sais “Corresponding AF Mounts: SIGMA, Canon, Sony and Nikon “.
It was a sigma error – it IS coming for A-mount. Read above!
er, if you read his comment you will see that he included Sony….
And the idiot of the month award goes to……. ME!
Sorry Daniel…
Nonsense, Zeiss is good investment, i keep telling me this 😛 :)) I mean, it’s here, isn’t it!? Behaving proudly like a Zeiss 😀 On the other hand it might take Sigma quite a while to get it out in A mount. You don’t have the price/IQ perspective yet. So, for now it isn’t a serious option, might be in the second part of 2014, who knows.
“and if this lens performs as good as expected it could get surprisingly close to the Zeiss Otus 50mm f/1.4 performance”
nice to start the day with a joke…
Why? The Otus is basically a lens where the designers weren’t tied to budget and size limitations. It might well be that Sigma followed their example and came up with this and chances are that this lens has a similar performance, but a much nicer price.
Otus is very unique construction, that’s basically a high-resolution medium format lens adopted to Full Frame. That’s nothing alike, it’s more like old Sigma 50 in new packaging – which was better than Canon/Nikon/Sony 50s, but nowhere near the quality of Otus.
No, the new Sigma is a completly new design and very different from what Canikon offer. It’s very promising and I wouldn’t be surprised if it challenges the Otus. At least it will be on the level of the latest Sigma 35mm.
The Zeiss FE 55 1.8 comes closest to the Otus from what I’ve seen so far, though it’s a stop slower and hasn’t perfect corners. Sigma can’t do magic, a 50 1.4 at this size will maybe reach the performance of the Sony Zeiss but not the Otus.
It’s no alternative however for a walkaround lens on the A7, it’s too heavy and will be even more with an adapter.
Do you have a link you can provide. I really want to get the 55 1.8 but I think it cost too much for what it is. However if it is better than the zeiss 50mm 1.4 assuming it is the closest to the otus I may get it after all. I can’t find any comparisons. It would be great if someone did a sigma hsm 50 vs 55mm 1.8 vs Zeiss 50mm 1.4
Is the 50mm Zeiss weather sealed.
You gotta count in German manual assembly labor costs vs. Japanese automation, and of course metal fabrication processes vs. full plastic molding.
It’s totally possible in terms of MTF, but there’s no chance the Sigma would get anything close to the Zeiss colors. German glass is German glass, period.
Then, all those people claiming to see Zeiss colors in ZM lenses produced by Cosina in Japan must be totally retarded.
I know some do, but it’s not the same thing, maybe they’ve mistaken late-Contax MMJ colors for the early AEG and Contarex colors.
I wonder if it’s a deliberate decision to not release a full frame E-mount version. I guess it’s because they don’t need the complex retrofocus design on mirrorless systems.
I’m seriously wondering what they’re cooking up for the A7(r). My 40 year old Jupiter-8 (50mm f/2) is very compact and has decent performance with its 80 year old Sonnar design. That lens with modern optical design, modern coatings and autofocus and a sub-€200 price would be a wonderful addition to my A7.
IMO retrofocus is the future for all high performance lenses unless the sensor design undergoes radical renovation, you’ve seen that current symmetrical designs all have serious falloff, and nobody wants falloff these days, they also yield serious color cast.
The 15mm for M-mount from Zeiss for example is a Distagon, considering the flange range it could have been a Biogon.
When they say ‘retrofocus’ does retro imply ‘behind’, rather than in front of the lens?
If that is the case, videographers would love this lens. We typically stick with internal focus and internal zoom lens (for matte-box purposes).
I know a lot of my friends already own the 18-35mm f/1.8! An amazing lens!!!
No retrofocus means…a reverse telephoto design, kind of, but certainly not internal focusing lenses.
“I wonder if it’s a deliberate decision to not release a full frame E-mount version” – yes it is. Reason being: sales.
FYI: Sales of mirrorless dropped significantly world-wide, in Europe it’s as much as -40% during holiday season. That doesn’t inspire anyone to get in that high risk-low reward market.
Yep, sales. They also cannot sell that to m43 users like the APS-C versions and they don’t have their own FF cameras either.
With the Winter Olympics coming up I really hope Sony would show off a new Pro-sports camera and telephoto lenses
Going on past history, that is incredibly unlikely. 😀
Joe. I would be wary of any dreams of Sony making serious effort in the pro sports market
Overall, Sigma once again makes the most interesting and relevant news in A-mount.
I’ve calmly accepted that by entering the world of Sony, I have also hitched my wagon to 3rd party camera companies for the best optics in many cases.
I don’t see why they can’t, they just need one system to compete against the 1DC, and release a few more telephoto lenses such as a 400mm and 600mm
Sony doesn’t need only good cameras and lenses. They need one other thing: dedication towards their product lines. That’s Sony’s biggest problem. Canon’s EOS system exists since 1987 with service around the world, that’s the reliability a pro photographer needs.
If you put it that way, Nikon’s done the best since the basic F mount design’s been around since the…60s?
You need to make decisions when necessary, Canon’s done itself and its users a big favor by switching to the EF mount with a bigger throat diameter, it makes lens designing easier.
Sony also should’ve followed tradition and come up with a new larger battery for its FF E mount cameras, it’s pointless pondering over how NEX users would dispose of their batteries when they go FF, if they have the cash to go FF, they have the cash to buy new batteries.
Now everybody’s complaining over a7/r’s battery life.
Nice , now when is that 24-70 2.0 coming?
NOT LISTED FOR SONY !!! JUST FOR CANON, NIKON and SIGMA
How many times does the Admin have to correct you people – you’re wrong! Read above!
If you bothered to look at the time on the comments you would see that the Admin changed it AFTER the comments were made.
I already won the idiot of the month award, please don’t rub any more salt in the wound! It burns!
24-70 2.0 will appear Photokina2014.
NEW 50 1.4 will be sold $1,000 or so .
Spring Canon , summer Nikon , then autumn Sony.
I wonder how much weight it is . Around 750(700-800)g.
Was the 24-70 f2 ever actually confirmed? Or just a rumour with a fake pic?
発売日、価格未定
対応マウント：シグマ用、キヤノン用、ソニー用、ニコン用

In japanese official sight , there is ソニー name on it.
October or so , sony A mount type will come sure .
That’s quite quick. I’m impressed. Let’s see if they do deliver like they say – cause Sigma is known from delays.
I already purchased the ZA 50mm f/1.4 and even though it is most assuredly priced higher than the announced Sigma Art 50mm f/1.4, I won’t be having any buyer’s remorse. Mine is attached to my a99 most of the time and performs spectacularly, and for the first time I don’t worry at all about going out in inclement weather with the combination. People who complain about purchases of lenses (or cameras for that matter) when something comparable or even better (which is most of the time arguable) appears should not have purchased it in the first place. Be satisfied with what you have decided and use the equipment to the best of your ability. I have all of the Zeiss Primes and they are certainly at least comparable to, if not better than, similar focal lengths by any manufacturer.
I am so stoked right now. I really didn’t think this was coming, so good thing I didn’t pull the trigger on the zeiss 1.4. What an overpriced waste of money that is. Looks like I’ll be ebaying my sony 50mm and purchasing this. Way to go Sigma.
Honestly, what does it matter if they ‘announce’ these lenses in A-mount if they can’t get them shipped. Still waiting for other ‘announced’ A-mount versions to start shipping.
It will probably perform well, but sigma’s new lenses are so ugly.
How can you say that?! I think it’s general consensus that the new Sigma Global Vision line is unbelievably beautiful. The materials, the curves, the angles…it’s lightyears ahead of the uninspired, drab, tired look of Canon and Nikon and even Sony lenses.
Who cares how a lens looks? Surely it’s price and performance is all the matters…..
Solid concept – only the optics should matter.
But if this were true, they could make them out of hot pink aluminum with drawings of unicorns on the side and they’d sell just as well. I think aesthetics is absolutely HUGE in the purchasing process for the vast majority of consumers and professionals.
If you don’t care about how the things look like – why bother with photography? An inspiring, good-looking environment can be as important to the creative process and final product as performance of the equipment itself.
I disagree. For me, I need quality optics for my work, not pretty looking equipment. If it does the job as I need it done, I don’t care what it looks like. You should spend more time looking though the lens instead of looking at it.
On the screen they look nice, but in person, I think they look plasticky and feel awkward. The Canon 35mm 1.4 looks and feel much nicer than the Sigma 35mm. I think metal and rubber make for the best lens look and feel, but the sigmas just look and feel like plastic. But, I’m glad they’re making them. They are great lenses for little investment. I just can’t get behind the design.
True – they do miss a certain heft. But I think they feel just as solid and high quality. But…different opinions I suppose.
Sony?? No, say what you want about the price-performance ratio but Sony designs the best DSLR(SLT) bodies and lenses. If you want the modern/futuristic look, definitely Sony.
Nikons are undoubtedly the ugliest, every generation, except for the new D4s which seems somewhat improved.
But their lenses are still the ugliest. Maybe better than Tamron though, but Tamron…?Seriously?
Do I know… for the “ugliest lens” title certainly Canon Full Frame black lenses are a huge contender (AF-S with silver rings are nice, white teles are really good, but regular lenses not at all, and they age in very ugly way).
Ugly? LOL. No taste at all. And think you’re interested in photography which is all about ascetics.
These are one of the best-looking lenses on a market. I have no idea how can you say that they’re ugly.
If you mean the Nikons, oh I can’t imagine how you deem yourself a person with taste.
Though most AF lenses look bloated these days, still among them Nikkors are of the more swollen ones. Especially ugly are the focus rings with the wide grid patterns.
The new 58mm, is dead ugly. Not freakishly ugly from a pure aesthetics point of view, but considering that it’s nothing more than a special edition redo to match the Df, they definitely could’ve done better than that. It’s an indication that the best they could do aesthetically is–very ugly.
And it has a big hollow shell to mimic the look of macro lenses and other high performance normal lenses but the fact is that it isn’t good performing nor does it do macro, as Ken Rockwell pointed out. The best thing they may have done to that lens is make the golden parts more shiny.
Canon changed its surface texture half-way, the older versions do age in an ugly way but I haven’t noticed that in newer versions.
Besides, all Nikon does is its ugly black, no whites like Canon, if they can’t get black right they should try out the whites, it seems easier to get right, Sony(Minolta), Canon, Olympus(old OM mount) all got the white right.
Sounds good. Now I will hopefully see some additional rumors on the upcoming A-mounts to see what camera I will use with this lens.
Makes the FE 55mm look down-right tiny!
Sony needs to focus on the G series and basic sony lens line-up. You should not be forced between extremes. It makes no sense to offer a 50mm 1.4 for 499 and a 50mm 1.4 Zeiss for 1499.00. Where is the middle ground? The sony 50mm, while decent, should have better wide open performance for its own price range. It should also offer SSM. Every Zeiss should have SSM II IMO as well. It’s not a matter of absolute need. Is the fact that you pay the full price for the whole package. Their lens line-up seems all over the place.
I will buy this lens for sure if its image quality is as good as the 35 1.4 Art, my Minolta 50 1.4 got oily blade last year 🙁
Just curious – how can an oily aperture blade affect image quality? If the blades were sticking I could understand, but being oily should not affect the lens at all.
if the oil is on the actual blade it will get sticky and slow the blade movement, making images shot at higher apertures over exposed
I’m interested in using some of these A-mount lenses on my NEX-6 with the LAEA-2 adapter. Will I lose stops with the adapter, or will I still get an F stop’s rated speed? Secondarily, will the adapter reduce the minimum focusing distance just like an extension tube would? Thanks
the lens will behave just like on an a-mount camera. the adapter is a great product. in most cases, af will be better than with native e-mount lenses. the only downside: low light performance will be a tiny bit worse than without the adapter. nothing to worry about imho.
a-mount has a longer distance between lens and sensor than the e-mount. the adapter adds the distance that those lenses are designed to have. and it has an af system built in.
Need specs, pics and previews please.
Thanks
Have tried the 35mm ART in Canon and found it a long way out on the focus….I won’t be buying.
I picked up the 35mm Sony F/1.4 G second hand for $850 Mint and it’s produces nice results on my FF camera.
I am still thinking about a 50mm f1.4. I passed on the ZA 50 f1.4 due to price I was thinking of getting the sigma 18-35 f1.8 for my a77 and the sigma 50 f1.4 hsm for my a99. In the end decided to buy just the sigma 50 1.4 hsm. While I like it for the studio I do not use it outdoors much. It is terrible when pointing it toward the sun due to heavy flaring and it is unusable. So I will follow the reviews on the sigma art 50 1.4.
