The Novoflex NEX/EOS adaptor is a totally mechanical version. With original Canon EF-lenses aperture control is impossible.
This adapter is designed for EF mount lenses that utilize their own aperture control ring such as Canon EF Cine-Objektive, Zeiss Compact Prime-Objektive, Samyang, etc.
It provides a perfect fitting between the lens and camera.
Note: This adaptor will not allow camera to send signals to the lens, therefore, functions as Av, Tv, and auto focus will be disabled.
The models SONY Alpha 7 and 7R make use of Sony’s E-Mount!
(All Novoflex adaptors are designed to focus to infinity)
