Ethics statement: I have no affiliation or financial arrangement with either Metabones or Conorus. I was loaned these adaptors to test. In fact, it cost me a few hundred pounds, as I had to buy two lenses to actually test them as I own no Leica R or Contax C/Y glass (tip jar donations on the Vimeo page are always appreciated! )
I have site sponsors/ affiliates and they are detailed in my main ethics statement which is linked at the top of the menu. These correspond with the banners within this post which are there to help keep this one man band site running, which is quite a task, so any click throughs are enormously appreciated.
I am trying to have a more attractive Zen outlook on life. So I am selling a load of my gear. Nowhere near most of it. Just a tiny fraction, but it’s time to do it and de-clutter my life, and that means regaining my house and avoiding being on hoarders.
There is nothing wrong with gear. Far from it. It’s all superb. I just never use a lot of it. So why take up space in a cupboard when I can give it to a good home and at same time help in my quest for a better life/ work balance? (You can read my incredibly important post about that )
If there are any bits of gear you need…whether it’s cameras, lenses, monitors (tripods coming soon) and so much more to come, do check out my ebay store. Everything is an auction with no reserve. There are going to be some awesome bargains there!

One of my biggest issues with the Blackmagic Cinema camera is its bloody awkward “in-between” sensor size. It’s not micro four thirds…it’s not super 16…just somewhere in between. This is a pain, as no glass is specifically made for this size. Super 16 glass vignettes, micro four thirds glass (both only possible on the MFT version) you waste some of it and with the lack of active MFT mount on this version of the camera, your MFT glass choice is damn limited anyway. The EF version gives you few options when it comes to glass choice. With a fixed EF mount you are limited to Canon glass, Nikon glass, Contax M43 and a few others…basically anything that has a flange distance the same or greater than the EF flange distance.
That is why I mostly prefer the MFT version. We lose that flange issue but also lose the ability to use Canon glass or any powered glass due to the passive mount. We can still use Canon glass, but we need a self powered adopter like the (non IS) redrockmicro one, which is quite old now, and the expensive but IS supporting MTF services ones. My two reviews of the cameras are the bottom of this post.
Metabones, who in association with Conorus have brought us an excellent EF lens adaptor for Sony E-mount cameras like the FS100, 700 and many stills cameras under the NEX umbrella. It’s powered by the camera, supports IS and lets us change the iris. Then they brought us the “Speed Booster” for these cameras. An astonishing piece of kit that I cover fully here….in essence it focuses the light from the lens projecting a larger image that is almost a stop brighter and somewhat sharper. Yes voodoo or almost Blackmagic (come on…I had to!)
I bought the Speedbooster for my FS700 after testing the preproduction one. Like many, I have eagerly been awaiting the one for the MFT mount. They are apparently still working on it, but in the meantime they have sent me the CONTAX C/Y M43 and Leica R version to test out. Unfortunately as the flange distance on both of these is greater than a Canon and Nikon lens, there is no adaptor to use my existing glass on these pre-production ones. I don’t own any Contax M43 or Leica R mount glass (I do have a few Leica M ones but they are even worse!) so I bought a lens for each on eBay purely to test these mounts out.
I have only had a brief chance to test out the adaptor, as I am actually on holiday right now (I really shouldn’t be writing this to be honest, so I had better make it quick!) as it’s almost yet another birthday (Monday) and a step closer to a half a century. Grim! So do take this on board when checking out the video. I need to do way more tests in different lighting situations, F-stops and lenses. For now all I have done is use the second hand Carl Zeiss Planar C/Y F1.7 T lens at F1.7. Not the sharpest aperture by far, but as I said this was done quickly before we left for the airport, and I didn’t want to bring it all with me on holiday! The lens is fine, just not exactly super sharp wide open or sharp edge to edge, so do remember that and do check back in a week and a half once I have updated this with a couple more examples.
So does it work? Absolutely. You can see clearly from the image below. It’s the same shot. Same camera, same light, same position just one is a passive flange distance adaptor the other the speedbooster. The full image is the speedbooster one which is clearly brighter, guesstimating it as about a stop brighter. I shrank the non speedbooster shot to 71% to perfectly line up with the speed booster shot. That means, unscientifically the adaptor is giving almost a 1/3rd increase in the field of view. I couldn’t work out the exact fraction so to be more precise it’s 29%
We are getting damn close to a field of view of a super 35mm sensor with this increase! Is the aesthetic similar? Possibly. I didn’t do anywhere near enough comparisons to see this, but as the NEX speed booster gives us a very similar aesthetic on a S35 sensor to a full frame camera, it’s entirely possible. I did a simple comparison with my 1DC in super 35mm HD mode to show how damn close it is. The shot isn’t exactly matched position-wise as the 1DC is taller than the Blackmagic. Remember, this is a simple field of view test only. No colour matching was done and any S35mm camera could have been used! This was just easiest as it was ready to go with me to Crete!
Also if we out this adaptor on a camera with an MFT sensor like a GH3 or GH2 or AF100 (I am selling both a GH2 and AF100 in my above mentioned eBay sale!) then we are getting a larger image than Super 35mm! Crazy stuff.
Now remember this adaptor will not work on a canon mount Blackmagic camera, whether the cinema camera or 4k Production camera. The flange distance precludes this. If you don’t get it then please read up on flange distances and understand all lenses are designed to focus at a specific distance from a sensor. An EF mount naturally means Canon glass hits the sensor at exactly the right point, giving us perfect back focus and infinity. Nikon glass can go on an EF mount as it is designed to the sensor at a slightest bigger distance than a Canon lens, that’s why the adaptor for Nikon to EF is a simple bit of metal that does two things, change the mechanical fitting of glass and put the lens the right distance to the sensor. You can’t get an adaptor to make a lens sit closer to the sensor than the camera mount on it. The fitted mount gets in the way!
Anyway enough technobabble. Check out simple test. Remember what I said about things to take into consideration. Enjoy one of the greatest English composers ever (alongside Gustavison Holst) Edward Elgar and his beautiful Cello Concerto. Appropriate music? I don’t care. It’s a lovely piece of music that far too many people will never have heard, and yes I cut out just as it gets to best bit!
