Kipon EOS to NEX adapter with built in aperture control.
I can imagine that some of our readers do own Canon lenses they would love to use on their NEX cameras. Until today you had no way to control the aperture of the Canon lenses using the currently available adapters. Kipon now provides a solution for your problem. they made an EOS to NEX adapter with built-in aperture control! You can find a review including image samples at the japanese website DC.watch (Click here). They tested the 50mm f/1.4 USM and 24-70mm f/2.8 Canon lenses.
If you have “Canon-friends” you might mention them the adapter to help them to buy a into the NEX system

It should be perfectly possible as E-mount specifications are disclosed now and there’s a firm that converts Contax N Zeiss lenses to EF mount – both – aperture and AF work!!! See here:

An electronic control over the len’s aperture is still the holy grail. It can be done. No one with the resources to pull it off has tried yet. I would be happy with manual aperture control. Camera controlled aperture would be awesome.

I agree the placing of the aperture at this point is optically naive. Sort of worrying really.

One other thing to consider is that the max aperture on the lens decides the aperture not the adapter. Yeay duh but I mean that if the lens is 2.8 the aperture ring will be around 6 for the first stop down. If the lens is 1.8 the aperture ring will be around 2 for the first stop down.
