The Novoflex NEX/CO adaptor is designed for M42 lenses to be mounted on Sony NEX cameras.
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)
