WOW. Do want, kinda.
So much for “But Canon has a bigger lens selection!” argument. Now every Canon lens is part of the M4/3 lineup!
Even before this announcement Micro Four Thirds already have access to more lenses than Canon!
Native or adapted? Adapted amount goes of course multiple times that Canon has but natives goes at least wider angle of view range.
Actually you get an even *WIDER* (by a little) angle of view than you do with Canon. (and heh, Nikon gives you a wider angle of view too than Canon! With their APS-C cameras)
Have you ever considered brain surgery? Or basic education? Were you educated in the US?
Leica speed booster please!

This is great news! I am all over this!
This is going to make it so much easier for Canon users to switch to Micro Four Thirds. Canon beware.
Mirrorless, although a great tool today, will have to advance much further before I turn in my 1Dx
Well, then you’re probably not into video that much. 😉
correct…no video here
Well, Photokina is just around the corner. I bet there’s good news for everyone there. 😀
24×36 will always advance too, so for people who need it, willl always go to bigger sensors
The so called “need” of many is an issue between the ears of those.
That doesn’t mean that some photographic area’s benefit from larger sensors but for the mainstream there’s no “need” to go larger, they already don’t use the potential that is available now in those “small” sensor camera’s.
sure true, but people who use certain rendering charactersistics of larger format(and i dont mean noise or similar performance stats) can benefit from the choices they make. Ofcourse most do like you mentioned, as can seen from how one writes. I am trying to go the polaroid way now for a change…….
Canon are crapping themselves all the way to the bank.
all I think about this great thing is legendary len sigma 18-35 F1.8
Yeah, 25-50 f/1.2.
Errr no, it becomes 13-25mm 1.2
I think he meant FF equivalent.
Only thing that would make it perfect is if it had optical stabilization for use on Panasonic cameras.
Will this also work on the BMPCC?
They already have had a version built specifically for that camera for a while. Not sure if this one will do double duty.
Yes it will.
I am sorry for your grey cells, both of them.
Better to go with the BMPCC version thats been out for a while since it takes the extra glass in front of the bmpcc sensor into concideration.
You can on the flip side use the bmpcc version on for example a GH4 if you disable the physcal shutter.
hmm any wide angle lens that can combat the upcoming 7/14?
Unfortunately M43 still does not have any ultra wide angle primes, i.e. wider then 24mm equivalent. Even worse, those somewhat wide prime lenses – 14mm, 15mm, 17mm, 19mm and 20mm, all have one problem or another, in AF, in resolution, in vignetting, etc.
Crossing fingers for the Olympus 9mm f/1.8 to be announced next month!
Rokinon makes a 7.5mm and 10mm manual focus lenses for m43.
Kowa 6mm is wider than 24mm chump…..maybe C-Mount but works super on the GH4 in 4K.
OMCG…..
there is a oly 9-18 currently. whereas the 7-14 is coming out next year.
are there any wide angle lens from canon equivalent to say oly 9-18 after conversion?
You have the wonderful Tokina 11-16/2.8 for EF
Can you use autofocus with this item?
No. It gives you in body control of aperture, and will report exif data with some lenses. The primary use for these will be for videographers. I bet alot of canon video guys will be snagging gh4/speedbooster combos to become their main rig.
i see len OIS can enable by this booster on eoshd.com
I wish they did it for Pentax – reason being, they actually have a set of small lenses, that would balance really nicely on MFT (ie DA limited series). 15mm F4, would make a nice ~21mm equiv F2.8 prime, with great build quality at some $600 bucks. Not too bad.
Except the number of Pentax lens owners is too insignificant for Metabones to bother. On the other hand, if they can make this adapter to AF EF lenses on M43 cameras, it will fly off the shelves in such huge numbers, the sky will darken for months. Maybe Panasonic and Olympus should subsidise that AF project. In the meantime, they can include such an adapter for a minimal amount in camera package deals and sell a lot of cameras to Canon users.
CDAF with PDAF lenses usually sucks, though…
Not on the E-M1
Ordered.
Looks like I made a very good choice keeping my favorite EF lenses (in order of new awesomeness)…
Sigma 120-300 f/2.8, now an 85-213 f/2
Voigtlander 40mm f/2.0, now a 28.5 f/1.4
Sigma 85mm f/1.4, now a 60 f/1.
Zeiss 100mm f/2 Makro-Planar (best bokeh I have ever seen), now a 71 f/1.4
With my Sigma 1.4xTC the 120-300 goes right back to being a 120-300 f/2.8, so that is pretty cool. Not too sure if the IQ will stand up though, but 85-213 f/2 will be great regardless. Of course it will be brought out rarely due to its size and limited uses.
The Voigtlander is a pancake, so it will look pretty natural on an m4/3rds body, even with the adapter.
60mm f/1……I don’t think I need to say more.
And the Zeiss…. This thing is a bokeh god. Worst case it has smooth and creamy bokeh, best case, with just the right subject/background separation, you would swear the background is a painting.
The image sharpness will nicely improve on all those as well.
I’d like a bit of clarification here.
Is the 0,71 factor with or without crop factor included in the calculation?
Is it
(focal length) x 0,71
or
(focal length) x (crop factor) x 0,71
?
I mean in terms of full frame equivalent, of course.
yeah I agree, we need to remember that it makes the lens wider at it’s native range, but then you’ll have to multiply by 2 at some point to get the effective range on an M43 right? So…
lens mm x 0,71 x 2?
Keep it simple: with the speed booster the crop factor becomes 1.42X instead of 2X. So a 100mm lens becomes a 142mm equivalent — not 71mm as stated above. A 50mm lens becomes 71mm equivalent.
This in no way “Keeps it simple”. With your method I have to multiply EVERY lens I touch, now and forever. With my method I only have to multiply the lenses I use with a speed booster.
Yes, for FF equivalency you need to double the focal lengths listed above. I didn’t bother doing that because I shoot m4/3rds, so I know what to expect from a given focal length. For instance, the 100 f/1.4 will be a little bit wider and a little bit faster than the 75 f/1.8 I already use.
Also, mine has shipped, Fedex has it already, and it should arrive before the weekend.
ordered!!! Looks promising!!! Will be interesting with the 50 1.2 and 85 1.2
ORDERED!!! YAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
And you can use this on a sony e-mount apsc camera via a thin adapter. =)
such a gd news for multiple system user like myself. with lots of om lenses.
What adapter?? Link?
http://m43photo.blogspot.fi/2013/06/using-micro-four-thirds-lenses-on-sony.html
Does it take EF-S lenses?
No. EF-S flange distance is too short, and also has a smaller image circle.
How interested can you be when you don’t bother to read the announcement or the hands-on test?
Moderately, at this price. I own a focal reducer, but more reasonably priced.
Are there any speedboosters to boost native micro four thirds lenses?
Impossible.
It only works with lenses designed for a bigger sensor on a body with smaller sensor. This is because the big image circle of the lens is compressed onto the smaller sensor. With Micro Four Thirds lenses the image circle is designed to only cover the m4/3 sensor size, so a tele compressor like the Speed Booster would only project a brighter light in the centre of the picture. While there are some practical cases where this is still useful (e.g. BMPCC which has smaller than m4/3 sensor but still m4/3 mount), it is however still not possible due to the fact that anything that goes between the body and the lens changes the distance from lens to sensor.
It could work with native FT lenses. I’d love that.
Still wouldn’t work. 4/3 lenses have pretty mich the same image circle as an M4/3 lens, only designed for a longer flange distance. You need lenses for APS-C or large in order to speedboost.
No, it couldn’t. Same sensor size.
Hoping for a Sony Alpha/Minolta lens to m43 speedbooster myself, as I have some nice minolta lenses.. (preferably electronic aperture…)
This is a blessing to all m43 users. Rumors are that a new full frame Sigma f/2 zoom will be announced at Photokina. That would give m43 users an constant f/1.4 lens for amazing DOF control and light gathering ability. It will probably be large, yes, but likely still smaller than the sum of multiple primes of the same aperture. A great walk-around lens when you only want one lens.
A 24-70mm f/2 lens is not so useful to m43, even with a speed booster. Sigma has already the 18-35mm f/1,8 winch makes more sense.
Does the 18-35 f/1.8 work well on M4/3 with a speedbooster in between?
It works extremely good!
You can find numerous video and stills samples of this setup online. 12.5-25mm f/1.2 makes for a heck of a great indoor zoom lens, especially for video.
Not useful to whom? It will be roughly a 34-100mm f/1.4 equivalent, which I find pretty darn useful. At least the rumored lens has a much larger range than the f/1.8 zoom, no vignetting issues as it covers a full frame sensor instead of APS-C, and best of all it will optically stabilized. I think most people would find these qualities useful.
I’ve used it on an EOS 10D (APS-C) for years, and it’s a great lens indeed. But I doubt if the stabilisation works with the speed booster.
Wrong. The EF mount speedbooster is an active one and most definitely will work with a lens’s stabilization ability.
I will buy this adapter without the 0,71x wider factor. To use my long Canon telephoto lenses in my Olympus M1 using the useful 2x crop factor.
FYI….this will not work on the EM-1. The adapter cannot clear the viewfinder hump!!!! I know due to first hand experience…too bad. It’s also worth mentioning that I did not find the quality to be particularly good. The optic are held in place by two set screws and a shim. When I received my the optics had fallen out.
Purchased. I have a non-electronic Chinese made focal reducer, but I will love the tripod support foot and the back focus is not quite right, so hopefully metabones quality is better. (Which I’m sure it is)
finally! This is the one I’ve been waiting for.
Let me see: you replace a Canon body with a m43 body. You get bad autofocus, bad image quality and bad controls, but… But what? But nothing, it’s just bad. LOL
I’d love to see the faces of the two geniuses buying this.
You know nothing, Jon Snow!
Dear anonymous internet expert, I guessed you missed this during your obsessive trolling of this site;
http://www.43rumors.com/weekly-43rumors-readers-pictures-roundup-12/
You’re welcome.
balls dropped already? relax and learn, broken teenagers of the world…
SD! Sorry to distract you from your obsession with male genitalia, but did actually you check out the link?
The pictures there directly contradict your nonsensical rant, but man up and check them out.
autofocus is not essential. As a matter of fact, it’s a very new thing that photographers have managed to do just fine without for over 100 years. And since every other control works, what bad controls are you referring to? As for quality, typical idiots think quantity equals quality – by this I mean megapixels and square inches do not a better picture make.
You think that? Basing on what? No wait, don’t bother.
LOL: you are so right, this is comically stupid. It’s also really expensive, those two nincompoops must be loaded.
Really expensive? Compared to what? Let me guess, you shoot with your kit lens. Or even more likely, you think your cellphone camera and instagram is the pinnacle of photographic excellence. You can go back to shooting duckface selfies in your bathroom mirror now.
Two? At least four or five, given the amount of superb intellects in these pages 🙂
This must be the stupidest product in the whole m43 system – which is not exactly the best camera system around, either.
Watching out for funny angry replies…
You betray your ignorance regarding m43. Pro videographers very frequently use a follow focus. Mine is wireless, made in the UK, but old-school manual ones are fine, too, if you are on a tighter budget. The image quality of the speedbooster is very good actually, which you would know if you had a clue. LOL indeed. Keep posting so we can have some more laughs.
What a CLUELESS penis.
Why do they have two versions of the EF Speed booster on their page both mention electronic both mention aperture control on camera none mentions AF?
One is $399 and other $599?
http://www.metabones.com/products/?c=micro-43-system-2
I believe the lower cost version is not a speed booster, just electronic ef
the $399 adapter lacks the glass element which brings the 0.71 factor in terms of focal length
Smart adapter is without glass. That’s what you’d want if you prefer to keep the 2x crop factor. E.g when you want max tele effect. If you want to keep the lenses as wide as possible, then get the Speed booster.
AF is not supported on either, but IS, Exit and aperture control are.
…or just remove the glass from the SB which is easily done.
I pray they design an active F-Mount speed booster next. I really need VR from my lenses
finally this is out! this will sell like crazy for videographers
Anyone know if the GH4 dedicated Speedbooster is still happening?
Can someone pls reach out to Metabones and find out?
