Video: Is Metabones Working On A SpeedBooster For EOS M?

SpeedBooster For EOS M? That’s what the videos above and below suggests (by user ckstoa on YouTube). The video above shows an adapter taken from a box with Metabones written on. The used camera is clearly an EOS M (the AF for sure :-) ). In the video below you can clearly see the Metabones logo on the adapter. Is this a prototype undergoing testing? Metabones never mentioned the EOS M mount explicitly, they were just stating that “support for other mounts will be added in the future”.

Interesting news! Would be cool to have a Speed Booster for the Canon EOS M (price & specs). Btw, the EOS M used in the videos has Magic Lantern installed on it.

Thanks to the reader who sent in the link.

Metabones Speed Booster First Impressions (DPreview)

Metabones Speed Booster First Impressions

DPreview tested the Metabones Speed Booster for Canon EF lenses to Sony NEX mounts ($599, click here). They used a Sony NEX-6 (price & specs) for testing. All the marvels this adapter promises to deliver are once more confirmed. It is, definitely, a game changer. I think we will se great thing in the near future done with this adapter. In their conclusion DPreview writes:

There’s a lot to be excited about with a product that so transforms lens behavior and addresses such a long-standing issue for photographers who long for the wide-angle and light-gathering performance of their older full frame lenses on their newer APS-C body. Image quality is very impressive, with results that compare exceptionally well against a full frame sensor. You do pay a small price in terms of corner softness and CA.

The biggest remaining challenge, however, with the Canon EF to Sony NEX mount is AF speed, a direct consequence of pairing a PDAF-optimized lens on a CDAF sensor. And to their credit, Metabones makes it very clear that AF performance is going to lag far behind what you’d get by using the Sony NEX’s conventional AF system.

This does effectively make the Speed Booster an even more niche product, as it’s best suited for manual-focus shooters. We’d be keen to see a camera manufacturer license this now-proven technology and offer this optical quality and near-full-frame performance mated with an effective AF system. But for now, we tip our hats to Metabones for releasing a product that accomplishes what many had thought nearly impossible.

 The optical quality is outstanding. DPreview’s first impressions comes with samples and good technical description.

R. Cicala’s Take On The Metabones Speed Booster

Metabones Speed Booster

All in all – if this adapter does not send shock waves through the camera industry I don’t know what will (Andrew Reid, EOSHD)

We reported yesterday about a full review of Metabones’ Speed Booster by EOSHD. Now it’s Roger Cicala’s turn to have a take on what is going to be the most intriguing and amazing photographic piece of gear since long. As I wrote yesterday, the Metabones Speed Booster was designed by Brian Caldwell and Wilfried Bittner, both of well known engineering fame. Btw, Caldwell discussed and anticipated the Speed Booster months ago on the dpreview forum, writing:

Designing focal reducers to fit 35mm SLR lenses onto mirrorless Sony NEX and m4/3 cameras is most definitely feasible. The design isn’t easy because there is very little room to work with, but if the magnification is restricted to 0.7x it can work surprisingly well at large apertures. Prepare yourself for optics as fast as f/0.90 by attaching a 0.7x (more accurately, 0.707x) reducer to an f/1.2 (more accurately, f/1.2599) SLR lens. And the reducer actually improves the MTF of the lens its attached to since it de-magnifies the aberrations.

So, we have two skilled engineers who claim to have done something that sounds like magic to most of us, we have a 30 pages white paper with all the technical and scientific galore, enthusiastic first impressions and reviews, and a lot of hype. EOSHD’s review gave us a first glance that the Speed Booster is going to maintain what it promises: faster and wider Canon full-frame lenses on Sony APS-C and Super-35mm E-mounts, and that very particular full-frame look and feel that many videographers want but often cannot afford. Being able to get full-frame aesthetics using a $599 (click here) adapter on a $1000-$1200 Sony NEX-7 or a $800-$100 Sony NEX-6 makes a big difference, at least when compared to a Canon EOS 5D Mark III (price & specs) which comes around $2900 for the body only. Full-frame look on APS-C sensor gear! If that is not going to scare someone in the executive floors of some well known Japanese camera manufacturers, what will then?

Roger Cicala is known for his humor and a pretty sceptical and thoroughgoing approach when testing gear. He got a Speed Booster, and here comes his take. First, a short yet understandable description about how Metabones’s wondertoy works:

A teleconverter spreads out the light leaving the lens so that only the center portion reaches the sensor. The result is the focal length of the lens seems longer (the image is magnified), but at the cost of reducing the amount of light (effective aperture) of the lens. The Speed Booster compresses the light leaving the lens onto a smaller image circle. This makes the focal length seem shorter and actually increases the amount of light reaching the sensor.

Metabones Speed Booster

The EF to NEX Speed Booster, for example, changes the effective focal length x 0.71, and increases the maximum aperture by 1 stop. A Canon 50mm f/1.2 lens effectively becomes a 35.5mm f/0.9 NEX lens, for example. Videographers all over the internet were singing Hosannah and laying palm leaves along the path of it’s introduction.

Roger did his tests using Canon EF 135mm f/2.0L USM (price & specs) and EF 50mm f/1.2L(price & specs) lenses on a Sony NEX-7. I really want you to jump over to lensrentals and read the test report on your own, it is full of insights and well explained technical stuff. However, I can’t avoid to quote Roger’s conclusion:

I think it was pretty obvious that I came armed for battle, ready to slam this product as some marketing overhype. I was wrong less correct than I might have been. The Speed Booster does what they claimed it would do, much to my shock and surprise. It creates a wider-angle, greater aperture lens while retaining resolution and acutance.

It does increase astigmatism a bit [...] It also seems to create some highlight blooming at very wide apertures. [...]

Most of the little foibles I’ve seen [...] really only apply to photographers trying to tweek every drop of resolution out of their high-resolution sensor. Video, even 5k video, is more forgiving of a slightly weak corner or a bit of astigmatism.

Update – More About The Metabones Speed Booster (Guess Which Is The FF Cam!)

Update: According to Japanese site dc.watch.impress the Metabones Speed Boost adapter will be on sale in Japan at the end of January 2013.

Update2: click here to read Metabones' white paper about the Speed Booster adapter. 30 pages of tech talk.

More About The Metabones Speed Booster. EOSHD did some simple but effective tests with Metabones' amazing Speed Booster adapter (we reported here). In short: the Metabones Speed Booster makes a lens wider and faster. Sounds like voodoo? It isn't, just clever engineering. To give a visual aid to what the adapater promises to deliver, have a look at the following two images. Only one was shot using a full-frame DSLR.

More About The Metabones Speed Booster

Image courtesy: EOSHD

Did you guess which pic was shot with the full-frame camera? Both pics were shot using a Sigma 24mm F1.8 (price & specs). The top one using a Sony NEX-7 (price & specs), the bottom pic using a Canon EOS 5D Mark III (price & specs)

As you can see the field of view is as good as identical. Quoting EOSHD: “The Speed Boost effect on aperture is highly evident too. On the NEX 7 the camera reports the maximum aperture as F1.3 and it is certainly brighter. [...the] “depth of field is as shallow on the NEX 7 as the 5D Mark III despite the difference in sensor size.

I agree with the following statement: “This is a groundbreaking product for photographers and cinematographers alike.” The EOSHD post has more samples to check and an exhaustive description on how this wonder thing works.

A synthetic description how the adapter works: “If your sensor is smaller than full frame, shrink the image that the lens throws to fit over it. That is the principal behind the Metabones Speed Booster which essentially gives you the full frame look and a brighter image all at once…

With this adapter:

  • A 24mm wide angle like the Canon 24mm F1.4L becomes a 24mm wide angle on the Sony FS100 (price & specs), with the same shallow DOF and field of view as on the 5D Mark III

  • A F1.2 aperture on a Canon lens becomes F0.90, a significant 1 stop brighter image in low light

  • Depth of field becomes shallower – the same as it would be on full frame
