Roger Cicala tested the two new Micro Four Thirds Speed Booster especially designed for the Blackmagic cameras. As you can see from the image on top it is physically impossible to use them on “regular” Olympus-Panasonic cameras with mechanical shutter.
One thing I completely missed to see is that for the first time you can actually shoot with a f/1.0 constant aperture zoom lens on a MFT camera! When using the Sigma 18-35mm f/1.8 zoom with the BMPCC adapter becomes, effectively, an 11.5-22.5mm f/1.0 zoom!
And what does Robert say about the quality of the new adapters? Read:
Once again, Metabones Speedboosters work their magic. This time it’s Blackmagic.
What can I say…LOL 😉

Well, the sigma with a speed booster wouldn’t quite = f/1.0 but rather f1.2. Still an amazing prospect.
From Metabones’ site:
“The new 0.58x Speed Booster reduces the crop factor of the BMPCC from 2.88x to 1.75x, and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74. For example, a 50mm f/1.2 now becomes a 29mm f/0.74, and the Sigma 18-35mm f/1.8 becomes the world’s fastest zoom lens at 10.5-20.3mm f/1.0 with stunningly sharp performance.”
It’s not the same 0.74x speed booster that’s available for other m4/3 cameras.
Robert Cicala –> Roger Cicala i guess…
ops 🙂
Do these alow control of apature and focus on m43? (said the NEX version will do slow focus with newer canon lenses)
I would idealy like EOS lens control (apature and focus and IS if poss) with m43 camera!
Could the blackmagic speedboosters work with the GM1? It has a different shutter mechanism.
good question! Will ask them.
From the camera labs review “Some of the space-saving is thanks to a new stepper-motor driven shutter mechanism, which is used to end exposures up to 1/500, after which a 100% electronic shutter takes over to speeds up to 1/16000; if you prefer you can use the electronic shutter regardless of the exposure for silent operation.”
This could be interesting.
I would not want to hear the shutter crash into the Adapter 😀
I believe that these BMCC adapters only cover super35 film format image circle. So mounting them on m4/3 would produce heavy vignetting at least.
I don’t get it, “One thing I completely missed to see is that for the first time you can actually shoot with a f/1.0 constant aperture zoom lens on a MFT camera!” ???
There are lenses from Slrmagic (Noktor) and Voigtlander (Nokton) that allow f/0.95 for quite some time now. Did I misunderstand something?
I’m stupid, missed the ZOOM part. Oops.
a sigma 18-35mm/f1.8 became 30-59mm/f1.0 Not 11.5-22.5mm f/1.0, at least is what i got after multiply for 1.7
lol, 1.8 times 1.7 is 1.0?! o_O
The one for Pocket Cinema Camera has factor 0.58, so it would be ~10.5-20.5 f/1
It depends where you are standing, you could walk back a few steps
I hope you are joking, otherwise Darwinism is going to wipe M43 users out….
He was joking. and you.. soon will become one of ussss
Actually I did nearly back up over a cliff once while framing a shot, the danger of using primes I guess
we normally look behind us when stepping back, at least i do 🙂
I use a spotter 😉
This guy certainly didn’t! 😀

It would be best to copy the URL to see this properly without a cut off screen.
Don’t you just feel so sorry for this guy & also the wedding couple.
Or do what I did, just double click on the youtube video to make it fullscreen 🙂
Thanks David. I learn something new every day. 😉
hahahaha that is hilarious, yes I do feel sorry, just a bit.
He should have used an Olympus Tough.. 🙂
Cameron, that was you right? 🙂
Prime lenses aren’t dangerous they been round since Buzz Armstrong landed on the moon. its Micro Four Thirds that are causing your problem.
do you mean Buzz Lightyear?
Good chance Buzz’s dad had them as well. They have been around as long as cameras. Strange that is it not?
you mean that if i put a 50 mm lens in a pocket camera it became a 29 mm. It mean that it has more DOF that a 5d mark III with a 50 mm lens?
It would have more DOF than a 5d3 without the adapter!
Ok, thank… For me just was really hard to believe it. thank,
50mm lens on BMPCC is 50 x 2.8 (BMPCC Crop) x 0.58 (Speed booster) = 80mm equivalent 35mm field of view
Which is pretty close to what an APSC sensor does, so basically it turns the BMPCC in to something that acts like an APSC camera.
However the light gather power is increased by about a stop.
Matt Jones, you right, finally i got a clear explanation. Thank, why people are saying that a 18-35 mm became 11-22 mm?. the real numbers are 30-59mm.
Because it does become a 11-22mm from an optical point of view. From a “35mm equivalent” point of view, with the 2.8x blackmagic crop factor that 11-22mm lens behave live a 30-59mm would behave on an ole 35mm film camera.
I wish we never used mm and always used FOV in degrees…
When you say “more DoF”, don’t you mean “less DoF”? It is that ‘paper thin’ DoF that is supposed to be so desirable! 😉
*If there would be no crop factor from the sensor involved 😀
I blame the French
What for, you’re incapacite to do mathematiques? Try a little harder my friend.
OK, on BMPCC, sigma 18-35mm f1.8 turns to a f1.0 with a 0,58x focal reducer. However, it works only because the BMPCC sensor is smaller (2.8x crop) than 4/3 sensors (2x crop).
I’m not sure about the maths, but I’d say a lens made for APS-C (1.5x crop) could not be used with such a focal reducer on a regular 4/3 sensor without producing hard vigneting, making it close to useless.
What would be the strongest focal reducer to be used without worsening performance from an APS-C lens to a 4/3 sensor?
I’d guess 1.5÷2=0.75x? But then I’m obviously discounting that these sensors don’t have the same aspect ratio.
And the strongest from APS-C to BMPCC: 1.5/2.8=0.54x? (with the same problem)
Of course, all of this is only in theory, as this current reducer design is bumping on the shutter mechanism of current regular m43 cameras.
that’s correct the NikonG-M43 speed booster is a 0.71 magnifier on regular M43 cameras (18mm x 13mm sensor). It is a different adaptor which does fit and does not interfere with the shutter. They have 3 NikonG-M43 speed boosters, regular M43, BMCC, and BMPCC
I don’t understand here that: if the lens matters 2.8, that is glass has ability to pass a certain amount of light how) it is possible to say what a certain adapter (from glass) turns value 2.8 in 1.0? I believe, what this certain wonderful adapter strengthens (disperses) photons which pass through glass of a lens and these photons getting to the adapter change the properties? HOW? Laws of physics are cancelled by the adapter? As far as I know, if the lens possesses certain properties, specifically ability flew down to pass a certain amount of light, this property can be worsened only, but to make a lens 2.8 lens 1.0! Yes you mentally ill people! ) )
These speed boosters typically increase the amount of light by 1 stop, so f2.8 becomes f2. The way they do this is the same way a magnifying glass works, by concentrating a large circle of light in to a smaller circle of light. That is why the field of view increases.
Still hoping for an OM to m43rds adapter… Thought it was supposed to be here by now?
Im gonna do what the cracker above said and cut a plastic magnifiy glass down and stick it in my adaptor see if hes right.
It might be possible to use an OM-Nikon F mount adaptor and then use the Nikon-M43 speed booster. http://www.ebay.com/itm/Mount-Adapter-Ring-for-Olympus-OM-lens-to-Nikon-F-Camera-D7100-D800-D600-D7000-/281220452197?pt=US_Lens_Adapters_Mounts_Tubes&hash=item417a0b8f65
Look I understand a magnifying glass in the sun can burn ants there is a lot of light there we know that. But it makes everything bigger it’s in the name magnify! So it should make all lenses like a telephoto. Like you are zooming in. It should crop more. So why are people saying different, this doesnt make any sense at all. I think its wrong and people are being tricked with the crop factor, has anyone even seen one of these things for real?
You should try to find a white wall with a window on the opposite side, then hold up your magnifying glass while moving closer and closer to the wall. Now how big is that magnification of the image of the window that is projected on the wall?
You just know he is going to injure himself doing this, just as the other gentlemen astonished us all by almost walking backwards off a cliff.
lol watch out for the cat!
Irwin? Irwin? Oh. Well…
f2.0 for m43 in real terms
No, it’s 1.0. 1.0 is 1.0. But green does great on you.
It just seems an awful lot of fussing about to try and improve your photographic experience. You could just go out and buy yourself a decent and robust DSLR with a full frame sensor and be done with it. Magnifying glasses, plastic, converters, adaptors I mean what in the world.
Full frame still is less versatile, while still being heavier, bulkier, and more expensive.
Precisely David, the versatility of the bigger, rugged, full frame can not be surpassed.
Well I guess that’s it then, we might as well close the forum down, put our cameras on Ebay, but who’d buy them? And go out and get Nikon DF’s and matching tweed sports coats. You Nong!
He said ‘less’.
I wish Randal said less on this forum and went back to Full Frame corner where they polish their mirrors and gaze in to their reflections all day.
I guess he feels he is being attacked, with these adapters those mirrorless seem to be able to invade into his full frame world.
Randal. You cannot even have this conversation about a 35mm sensor. So yes, 35mm is simpler. There are less options and less to play with.
Nikon have captured this beautifully with their pure photography message. A vastly customizable camera which by design does not take video, it has professional level controls at your finger tips. It allows you to walk bravely in to the streets with nothing but a DF and a defiant grin on your face and capture the world in a way no one has ever thought possible before.
You make me laugh, really:D
No matter if you are ff-troll or not. Maybe you should send your words to Nikon marketing department, I think they’d want to hire you.
And a strain in your back! And. A dropped shoulder from having one extra lens in a bag! Oh! Don’t forget all those dials! Wow! On a Nikon!!! how do you use them? Oh, yes put it on auto. Ahh! That looks pro now.
+1 lol exactly right, and the houndstooth sports coat
Dear Randall,
I do not stalk or troll FF forums, arguing that only st***d bodybuilders with tiny p***ses lug around FF cameras, that FF is dying, like the Graflex did, after the Leica M3 was born, only it does not know it yet, and keeps going, like a zombi, and so on.
It is a fundamental rule of civility that, in matters of taste and judgment, you have an obligation to respect our choice of trade-offs (size/weight v. low light ability), just as we respect yours.
Kindly s**t up and s*d off!
Yes, ” the bigger, rugged, full frame ” has the extra versatile use of being able to be used as a sledgehammer too.
oh so the em1 is better than a d4 1dx?
No, not for you, you still need to carry around a D4.
I can see the problem, you head over to 1Dx land, the Canon rumours site, Canon Watch and there are plenty of articles, but no one reading them. There is 1 comment on the first article, no comments on the second article. So the DSLR boys get lonely and need someone to talk to and come over here. They get frustrated at not being able to understand and properly join in and they lash out. Lets all be friends instead 😉
For my work, yes. For my hobby, also.
your is lame anyway
said the lamest and most immature guy ever lol
What happened to the speed booster/turbo adapters that were coming this years and even going to be better than the 1 stop APSC versions?
Another fiddly toy, another punch to image quality, as if that puny sensor wasn’t enough.
GM1 seems to be perfect pocket camera. EM1, GX7… are too big for that purpose.
But Full Frame is still needed when you need decent pic quality (dynamic range, …).
There is not such a thing as one camera to fit all situations.
