NEX Canon EOS Lens Aperture Control

Sony NEX-5 with Canon EF / EOS Lens Adapter with Aperture Control by Kipon

One problem with using Canon EF / EOS lenses on the Sony NEX is that there is no aperture ring and there is no way to control how much light the lens allows in. EOS / EF Lenses come off the Canon EOS body with the aperture locked wide open, unless you do the DOF preview trick.

The engineers at Kipon created a solution for this problem by introducing their own aperture blades and a ring to control the aperture for their Canon EOS / EF Lens to Sony NEX E-mount Adapter. The Kipon aperture ring goes from 1 (wide open) to 6 and beyond (stopped down). We are not sure if the 1 (wide open) setting is big enough for the the large aperture EF lenses (f/1.2).

The adapter will not work on these lenses: Canon EF-S 10-22mm; EF-S 15-85mm; EF-S 17-55mm; EF-S 17-85mm; EF-S 18-55mm; EF-S 18-135mm; EF-S 18-200mm; EF-S 55-250mm; EF-S 60mm.

If you have one of these adapters please send us a review and some photos. If you want to shoot wide open, you can use a regular Canon EOS / EF to Sony NEX lens adapter.
