Canon EF to Sony NEX Adaptor with Electronic Aperture Control

[Canon Rumors]

Share

From Conurus This is the world’s first adapter that would give Canon lens owners electronic contact with Nex cameras (such as changing aperture using the camera itself).

Estimated availability: January 21, 2012

So why would I need the Sony camera, exactly?

[dschapin]

Question would this work with the sony fs100 super35 video camera. Hope so

"So why would I need the Sony camera, exactly? "

If you look at the conclusion in dpreview it pretty much states that this is the best APS-C camera currently available in many regards such as IQ, sensitivity, resolution etc. "in terms of out-and-out image quality it's probably the best APS-C camera yet, regardless of size." and the only downside is the rather limited collection of glass available for the NEX- system. That being said IF the adapter works well, this could improve the value of the NEX-7 alot. On the other hand it's possible it degrades IQ too much (the adapter) or that the electronics don't work reliably.

...And the same company seem to also make some adapter to make Zeiss lenses autofocus on Canon camera.  Now that might be interesting if it really work!

.....and when do they announce their adapter for the Fujifilm X-Pro1 ?

[Neeneko]

oooooh.  I was wondering when they were going to get aperture control working ^_^

This increases the chances of my next camera being a NEX rather then something by Canon.  I have a lot of Canon glass... but the NEX can has the best UV performance in a consumer camera, which is the opposite of Canon's 'worst' rating.

This solves the last problem  to migrating to the NEX 7 from Canon. Now I'll be able to use the EF 90mm f2.8 TS-E for product shots      A side benefit is I'll be able to use the EF 86mm f1.8 USM while waiting for a E-mount Zeiss 85mm.

Guess it also means that I'll keep my Canon Elan 7n film camera 

Come on Canon, it's past time for you to build a Pro Quality Third Generation camera. What are you waiting for

It's not possible to degrade IQ with this adapter. There is no lens element in the adapter. It's just empty hole. That's the advantage of smaller flange distance of mirrorless system. You can adapt any lens ever made without any cost to the original optical performance of the lens.

For $400, I think I'll have to pass .  Right now I use an adapter that doesn't allow aperture control but it was only $20-30.  The focus peaking on the 5N works fine.

I picked up an EF to m43  adapter with a built in aperture some time ago. It works reasonably well, I don't notice any vignetting with the lenses that I use it with.  I've yet to test how much extra dof I get from it. Controlling the aperture of the lens directly would be nice, but with a price tag in the hundreds, I could pick up some Canon FD lenses (mechanical aperture) and adapt those instead.

nice.

but will it allow focus on 85 1.2 ?
if it does, I'll buy it right away


uuhhhh apparently it does!

Apart from changing the aperture, the lens image stabilization also works with this adapter. Plus exif data reports corrects focal length and aperture setting.

I doubt kenko will be far behind and they will produce one that costs half as much
