A VERY interesting and cheap Canon EF mount for the FS100

Read more in my full ethics statement here. 

I rarely post about new products that I have not touched, but this looks interesting enough to share…

I love the Sony FS100 because it’s cheap and produces a great image. It did incredibly well in my recent shootout. It’s not perfect. Build quality is a wee bit plastic. Fiddly to use, horribly buttons, no NDs, no HD-SDI… But, it’s an amazing image for the price!

Using Canon glass on these cameras is a big no no though, due to the electronic aperture control of these lenses. Nikon mount lenses (which I use on the FS100) have a mechanical lever which is easy to adjust. Not for EF glass.

I have a huge amount of quality EF glass, and this has been my biggest pain because they only really work on my Canon DSLRs, RED Epic and C300. Redrock do a nice adaptor for the AF100 but no IS using them and it’s a bit clunky and doesn’t work with the 85mm F1.2…There is a workaround adaptor the F3 but it has the same issues.

Birger have been promising that one will come out since the Napoleonic wars, but no sign of it yet! 😉

MTF services should have one soon but it’s a week bit bulky and expensive.

Apart from buying a C300, this looks like the best option yet…if it works. Now I MUST stress this. I have not used it, seen it, touched it, fiddled with it, shot with it, had  a conversation with it, taken it to dinner, gone on holiday with or had my way with it yet…all this is based PURELY upon specs. On those specs and the price of $395 could it be too good to be true!?


This is what is supported!

EF and EF-S lenses

Image stabilization (IS)

Electronic manual focusing (EF 85/1.2L, discontinued non-IS white telephotos, discontinued EF28-80/2.8-4L)

EXIF (focal length, aperture, lens ID) P, A, S, M exposure modes

Contax N mount lenses modified to Canon EF by Conurus

Contax 645 NAM-1 adapter modified to Canon EF by Conurus

Sigma, Tamron and Tokina lenses in Canon EF mount

So it’s powered by the camera (HUGE plus), we get EXIF data, supports IS, and I am assuming but cannot say for certain that it supports the 85mm F1.2. No idea of build quality, but this could be a great solution for me and the countless others wanting to use the FS100 with Canon Lenses.

Of course this will work with your NEX5N and NEX7 as it’s the same E-mount

They are currently sold out but you can keep an eye out on this page for pre-orders.

Here are a couple of pieces I shot for Sony with the FS100
