Blackmagic 2.5K & Pocket Effectively Become Super 35mm Cameras with New Speed Booster Adapters

Metabones_spnfg-bmpcc-bm1_03sThis year a company called Metabones released the Speed Booster, an adapter which makes lenses faster, wider, and sharper as long as they were designed for a larger format than the format you're currently working with. They already introduced adapters for Micro 4/3 cameras like the GH3, but now they've created new Nikon mount Speed Boosters designed specifically for the Blackmagic Cinema Camera and Blackmagic Pocket Cinema Camera that make lenses on those bodies even faster and wider, and give the Super 16mm Pocket essentially a Super 35mm sensor.

Here is Metabones on the BMCC adapter (the generic adapter already turned it into effectively a Super 35mm sensor, but now lenses are even wider):

The new 0.64x Speed Booster reduces the full-frame crop factor of the BMCC from 2.39x to 1.53x, thus effectively transforming it into a Super-35 format cine camera. In addition, the speed of any attached lens is increased by 11/3stops, with a maximum output aperture of f/0.80. For example, a 50mm f/1.2 becomes a 32mm f/0.80, and Sigma’s new 18-35mm f/1.8 will become an 11.5-22.5mm f/1.1.

And on the BMPCC adapter for the Pocket:

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.

These adapters also improve sharpness while increasing sensitivity:

In addition to increasing lens speed and field of view, both of the new Speed Boosters significantly increase the lens MTF.  The graph below compares MTF at 20 lp/mm for the Nikon 50mm f/1.2 by itself and combined with each of the new Speed Boosters.  For both the 0.58x and 0.64x versions there is a dramatic performance enhancement near the center of the image, but there is also a moderate performance improvement in the outer parts of the image as well.  This is especially impressive when you consider that the Speed Booster MTF is evaluated at f/0.80 and f/0.74, respectively, while the native 50mm lens is evaluated at f/1.2.

These adapters are made only for Nikon lenses at the moment, so it will be interesting if we get either standard Micro 4/3 or Blackmagic-specific Micro 4/3 adapters for Canon lenses at some point in the future. The issue with a Canon adapter is that those lenses need power to change the iris, and there is apparently some trouble making this work reliably from the Micro 4/3 mount (and a powered adapter would only work with the active Micro 4/3 Pocket). The biggest differences between these new Blackmagic Speed Boosters and the regular MFT Speed Booster is that the Metabones team was able to put the rear element farther back into the camera since there is no shutter on the video-only cameras (whereas there is one on cameras like GH2 or GH3). That's what allows these adapters to make the image even wider than before.

The BMPCC adapter will only work with the Pocket, but the adapter made for the 2.5K camera will work with both. Here's a chart for all compatibilities:

Metabones Blackmagic Speed Booster Crop Factors

 *) Based on diagonal field of view

**) Do not attempt to mount – physical damage may occur

***) Can be mounted, but does not cover the full sensor with most lenses

With these adapters, both Blackmagic cameras are effectively Super 35mm, so your crop factor is right around what it would be on any APS-C camera like a Canon 7D. The Pocket adapter also gives that camera close to 2 stops of light gain, which is helpful in lower light situations. Here is Philip Bloom with some examples:

This kind of performance does come at a price. While the generic MFT adapter is $430, these are going to be $490 when they ship sometime this month (though the Pocket may take a little longer). If you own both cameras, it might make sense to get one that works with both, but if you've just got a Pocket, it really becomes a totally different camera with the Pocket-specific Speed Booster.

That's a good question!
Without confirmation, it's just speculation, but I'd say there's a good chance they might work. Of course what with them being designed for smaller sensor sizes you might end up with a lot of vignetting unless you use only full-frame-image-circle lenses.

I'm actually not so sure they'd be compatible. The AF100 has a piece of ground glass that protects the sensor and ND filter wheel, and I wouldn't be surprised if the new adapters extend too far into the cavity and hit the glass. Of course, we won't know until someone tries, and I'd love to have the option for my AF, but it's something to think about.

That's a good point about the ND filter. I could see that being a problem.
Neither Backmagic camera has any sort of pre-sensor filters, even anti-aliasing filters, so that could help Metabones push the adapter's lens elements closer than with most other cameras.
Also, after doing some basic number crunching, it looks like even if it were to work, one would only be able to use full frame glass without running into substantial vignetting.

According to Philip Blooms review he says not to use it on other micro four thirds cameras. he said it would hit the shutter and cause damage to the camera.

But does the AF-100 have a physical shutter? It's a pure video camera with no still photo mode, so it most likely doesn't have one, meaning it's likely that there's nothing to get in the way of these new adapters.

even if there's no shutter to hit, the image circle won't cover the sensor: you'll end up with a hard vignette.

Can't be done - you need to use a lens with a large flange distance on a mount with a small flange distance, otherwise there's no space to physically fit the optics for the adapter. The only (common) lens mount with larger flange distance than EF is Nikon, and that's only by about 1mm - which isn't nearly enough to accomodate these optics.

You both need to do research. These only work on Black magic cameras, and you can't do this to an ef mount.

The original speedbooster adapters had a maximum input aperture, which I believe was f/1.2, so I would imagine these would have a similar limit.

Sony should put their 5K sensor on the RX10 and make an RX body with a built in focal reducer by Zeis and an outside Emount. Sou you can adapt any lens on it and enjoy FF loook, and 3 stops gain in speed.:D And have 1080p 60p to boot.

*noob alert*
Ok, this is most likely a very stupid question. So, this lets in lower light which is nice, and there is no more crop factor when using 35mm format lenses which is also nice. But, referring to the pictures above by Phillip Bloom; couldn't you just physically move the camera backwards a few feet and achieve somewhat the same look? Does that make sense? I mean, what do you gain from having an equivalent of a 35 mm sensor if you just stand farther away to get the same shot? Again, I'm a noob and this question might be painfully dumb.

That doesn't work If there is a wall or cliff behind you. This adaptor would be helpful for interior shoots, and when you want wider angle that can't be achieved in smaller sensors. I have shot super 16mm through my school years, and I never complained about its size. Some like to shoot in small sensor and some like to shoot in IMAX. I think it's all personal taste in the end.

A lot of films were shot in 16mm and 2/3", many tv movies and documentaries are still shot in 2/3". It's a good sensor format, I like it a lot. It allows you to shoulder mount a 20x wide-angle zoom with a constant f1.8, which is great for documentary.
Shallow depth of field is nice sometimes, but sometimes it can be a pain in the ass, too. 2/3" is great because you can get some shallow depth of field when you want to, but you can also get more sharpness when you need that.

the dof will change when you move the camera back. a full frame look allows for the possibility of being both wide and shallow, which is what the speed booster helps to achieve

and as yongy said, sometimes you don't have room to back up either

Not entirely a stupid question.
What you lose by simple moving the camera are aspects of depth of field and parallax. To be more simple about it, being close to your subject with a wider field of view often gives you a nicer look. Also, 'wides' shot at standard telephoto lengths (35/50/85) don't look as 'epic' as ones shot with a lens/sensor combo that gives you very wide field of view. That doesn't mean they're not useful as 'wides'.
The 'classic' film look for @50 years for example was 35/40mm on a 35mm size frame at T3.9 (@F4).
Many people still prize that exact combination of DOF, FOV etc. although we can now shoot at lower stops and much much wider.
However its not the end of the world if you start out shooting without cinemascope style wides. In the days of true 16mm we often never went wider than 35mm equiv FOV. On a non-metabones'd BMPCC that would be @12mm. There are plenty of 12mm lenses in the M43 universe.
The advantage of this unit to you is that now all Nikon mount lenses shoot significantly wider and faster, allowing you to compose differently, and closer to 'standard' S16/35mm cinema DOF, FOV and parallax.
The advantage of this fantastic unit to me is that being used to calling lenses and framing for 35 or full-frame, jumping to the Pocket Camera isn't quite the headf*ck it was a week ago.
For you as a noob, if this is your first camera, it will be a lot easier. :-)

first off, don't think of it like it lets in "lower light." speedboosters just make more of the light that the lens already lets in actually available to the sensor.

to your question - this stuff can be very confusing, especially when you get into all this sensor-size "35mm equivalent" jargon. basically, you're asking the difference between the effects of "cropping" and the effects of changing the focal length. 50mm is NOT the same as 35mm pushed a little closer. bokeh/depth of field and relative background size both change. watch examples of "vertigo" dolly/zoom shots to see examples of these changes happening mid shot. THAT SAID - 50mm without a speedbooster IS the same, optically, as 50mm WITH a speedbooster. it is just that the two images are cropped differently.

no, that wouldn't be quite the same. Of course you could get the same field of view by moving back, but the depth of field would change. See, not only the aperture and the focal length determine your bokeh, but also the distance from the subject in focus. The closer you can get to the object you want to focus, the "blurrier" you background is going to become. And even if you don't care too much for bokeh, there's other practical reasons like getting a wider framing in confined spaces

My guess is the quality of that might not be very good, because the more you compress the image, the better quality optics you must have. Maybe even more optical elements, than they have put in these adapters. I think for now they cannot make one, with a usable picture quality.

The real question now is whats the better choice, BMCC with speed booster or 4k Black Magic. My production company has been debating a preorder of the 4K Black Magic or one of the other million choices out there. So what do you guys think whats the pros and cons of one over the other?

Well, one exists, the other is vaporware for now. So, that's a major factor. Who knows how long before the 4K exists, and with RAW, etc. Not to mention there are a lot of 4k cameras on the horizon; if you can hold off for the BMCC 4k, I'd hold off to see what comes out early in 2014.

If you need it now, well, then your choice at the $2k price point is obvious.

Correct me if I'm wrong, but wouldn't this be the case…

A 50mm f1.4 on the pocket speed booster, being multiplied by .58 becomes a 29mm. Then, being multiplied by the 1.75 crop factor becomes a 50mm again, a true 50mm full frame equivalent at f1.0/f0.95.

The same would work for a 20mm for any other focal length if you do the math, so for the pocket this adapter essentially turns the camera into having a full frame sensor!

I am now feeling like this is completely wrong, but then it doesn't really make sense why they're saying a 50mm would become a 29mm, unless it was once again subjected to the lessened crop factor of 1.75x...

If you look closely at the table above, it says BMPPCC has a native crop factor of 3x.. And so they have given the effective crop factor as 1.75x
(I hope I am right. I myself am in doubt, because for other bodies they have clearly mentioned, do not mount. I don't understand why are others debating and quoting Philip Bloom for validation as the information is clearly in that table)

The BPCC's crop factor is 3.02.
Without the Booster, a 50 mm lens would render the same field of view as would a 151 mm lens on a full-frame camera. Adding the 0.58x Speed Booster would give the image the same field of view as an 87.6 mm lens on a full-frame camera.
Maybe you're confusing the *effect* the 0.58x Speed Booster is having with the camera's actual sensor size. While the camera's sensor, by itself, has a crop factor of 3.02, once the 0.58x Speed Booster is applied any lenses attached will render an image that looks as if the camera has a sensor size with a 1.75 crop factor -- that's only *after* the Booster has been applied, though.

Yes, thanks for clarifying.

I completely understand that the sensor size doesn't change, just the fov of the lens does.

The part I'm still confused about is they're saying that a 50mm would become a 29mm fov, since that would never actually happen...

Ah, I think I figured out what they mean by that. A 50mm equivalent (about 16mm) would now be a 29mm equivalent (16 multiplied by 1.75 equals 29).

It's just confusing the way they frased it, as there is no 16mm f1.2 Nikon that would be required for this scenario.

There's always this confusion with some focal length "becoming" another focal length through a crop factor. You can read it everywhere, but it's wrong. A focal length never becomes another focal length, it always keeps the same properties - only the angle of view on different sensor sizes differs, because a smaller sensor will record only a smaller part of the image that a certain focal length projects.

Well, in general, using an FX lens is an advantage because you are using the center of the glass and it results in better sharpness, less vignetting, etc. Theoretically the Speedbooster would produce even better results with FX over DX.

But, in the end, both will work fine. This is only projecting something that is slightly smaller than APS-C, so, a DX lens would be fine.

whats the best EF to MFT adaptor (with no iris control) out there? Do you guys know? I have a MFT BMCC and a set of EF Rokinons and I was expecting the spedbooster to come out this December, thats why I bought my MTF mount, but I have no knowledge on flange limits for these and I see products (normal EF to MFTadaptors) on ebay ranging from $9.99-$300.

Is there any reliable ones? I'd even be interested in getting one with iris if it has more blades that the Rokinons (8 blades). Let me know! I wanna be ready for the metabones ef to mft release and be able to use my Rokinons previously used on a 5D

I have Zeiss Contax lenses and can easily put a Nikon adapter on them so I presume that would work with the MFT mount BMCC? Anyone thinking the same thing?

I mean should I be looking at Nikons for full frame or crop sensor?

It would be great if someone produced a simple table that showed something like this:

Lens = Speedbooster = Camera Sensor = Crop Factor, Vignette

In which you can choose your speedbooster and then see what lenses fit and to what camera and hence crop factor. Doesn't have to have visuals, just the quick math and specs.

So they might make an EF to EF adapter for the BM camera? If the speedbooster works as well as it should, then using such an adapter on an EF mount camera to use EF lenses would be great.
Does this make sense?

My question is this...if you've done the tests on the 2.5 k and 4 k BMCC; and you know how to either adjust for the visual distinctive differences for audience approval and understanding between the 2.5 l look and the 4 k look...and you put this speed booster adapter on the 2.5 k, then:

Why even go with the 4 k?
Why spend the extra coin?

Let's face it...if all things are close to the same ( and the auds don't really see the diff.), why go with the 4k?

@Mark The 4K BMCC will also add 60fps recording, and for some people 4K will be preferred over 2,5K when they have big-screen purposes in mind for instance. Also a native super 35mm sensor will be more pleasing than the hassle with adapters, specially if you're planning on using EF-mount lenses.

"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."

Wouldn't the Sigma 18-35mm end up as a 21-40.6mm on the BMPCC not a 10.5-20.3mm?
Here is my math. The Sigma is a 18-35 times 0.58x widening of the lens making it 10.5-20.3mm. It is a APSC lenes so the crop factor is by 2x not 3x. So that makes it a 21-40.6mm lens...? If I am totally off please explain, or better yet just tell me the mm's equivalent to a 35mm on a DSLR. Thanks!

Does anyone know how this effects Rolling Shutter?

I know its sensor readout that shows the rolling shutter but a wide angle lens tends to be more forgiving for rolling shutter (especially when handheld) and shot stability.

For example, If i was to put a 20mm lens on without a speedbooster and a 35mm with the speed booster, would the rolling shutter effect, or the sense of stability be the same, given the same fov? Or would the longer lens accentuate movement and the rolling shutter even though the fov is the same?

That's not possible, according to Metabones.

that's hysterical so many films have been made 2k and looked amazing on the big screen,

Skyfall
Slumdog
Sherlock Homes
Gravity
Life of Pi
All Arri Alexa 2k

Upstream Color was filmed on a GH2

Really enough of this ridiculous notion that everything needs to be 4k!

FYI BMCC 4k you lose 1 stop of light and is lossless 4k not raw.

Skyfall looks great but Upstream Color is pretty grim looking. Doesn't really advocate for cheap DSLR film making. The real advantage for 4K camera would be to shoot in 4K but finish in 2K DCI. This gives you all kinds of room for recropping and FX in post, as well as a lot more detail and less visible digital noise throughout the film (using the right post tool, say Davinci Resolve).

Speedbooster is great. The only drawback is, and it's a BIG one is that the vintage Nikkor lenses won't fit there, even being F mount. It's really a pain in the ass, because I can't use my old 50mm f/1.4 on it. I've used it on a D90 and even on a Canon 60D with an adapter with no problems. On the SpeedBooster it fits, but it won't rotate to a locked position. I've contacted Metabones and they told me in macaronic english that those lenses are incompatible and there's nothing they can do about it. Yes you do Metabones. You could warn costumers BEFORE they purchase.

Does anyone experienced this, or is it just me?

The Thing IS I Have A Nippon PL Lens And Its A 50 75MM Lens.

BMCC MFT > Metabones Speed Boster > PL Mount Adapter.

If I Do This,Does The Film Will Come ON 35 MM Sensor?

Final output is hardly the purpose of most 4K acquisition anyway - at least until 4K sets gain traction among consumers which is probably a long way off. Those who have the hardware for it shoot at 4K for its advantages in post production like ability to crop without losing image quality when outputting to 2K or 1080p etc.

Use full frame lenses on the pocket cinema camera with metabones speed booster!

Because, the full frame lens does function on full frame sensor AND also on a smaller sensor, because the full frame lens is bigger than the sensor!

And: you can uses this full frame lenses on lots of other cameras and on movie cameras!

And: lenses tend to have a bit anomalies on the edges, therefore, if you put a full frame lens on a smaller sensor, this problem will be much less or will disappear!

The 4 K Blackmagic has Global Shutter.
If you move the camera faster, or shoot action secuences, where the objects are faster, the 4K Blackmagic Camera will record everything fine, the 2,5K Blackmagic will have rolling shutter effect - means: the image or the objects will be askew!

you must multiply with 1,75 if you put on the pocket cam a metabones speed booster made for the pocket cam !

an 18-35 mm objective would become on a blackmagic pocket with metabones speed booster made for pocket cam:
31,5 - 61,25 mm lens!

look at the chart where 1,75 stands - if you put on the pocket cam the speed booster made for the pocket cam, then the pocket cam has a crop factor of 1,75.

if you put on the pocket cam the speed booster made for micro 4/3, then the pocket cam has a crop factor of 2,14.

the pocket cam has a native crop factor of 3,02.

all numbers a written on the chart above, which is in the artikle.

Wow, I've just gone through a couple threads on this site until I my head got numb and I realize now how easy it is to lose focus and drift into a world of details that are irrelevant as far as filmmaking is concerned. It's good to know this product came out, but all these questions and conversations are a waste of time. And it looks like there's a second page too!

If you've been planning to shoot a super-low budget movie for a while, but you're a dozen thousand dollars short, and you're stuck because you don't know where to get it anymore, and you want your movie to look at least like "digital 35mm", all you need to know is:

"This year a company called Metabones released Nikon mount "Speed Boosters" for the Blackmagic Cinema and Pocket Cinema cameras that make lenses on those bodies faster, wider, and give the Super 16mm Pocket essentially a Super 35mm sensor."

So you do a little test shoot. Then you look at the footage with your DP. If it looks good enough, you start pre-production. If it doesn't cut it, you keep looking for another solution. That's it, or you'll never make that movie.
