CameraPlus - AT-EF-NEX II Auto Focus Canon EF Lens to Sony NEX Adapter for Full-frame A7/A7R/A7S Cameras with E-mount Built-in Hand-shaking Function - Same as Metabones Mark III MB-EF-E-BM3

Features:
1. True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
2. EXIF data such as lens identification, focal length and aperture.

Note:
1. Vignetting at corners may occur for certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony NEX has a 1.5x crop sensor.
2. A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
3. Sigma 17-70/2.8-4 OS HSM may occasionally run into a focus accuracy issue at the telephoto end.

Compatible:
With fully manual lenses which have no electrical contacts. Customers have reported success with the following fully manual lenses.
Samyang 35/1.4 ; Zeiss CP.2 25mm/T2.9 ; Zeiss CP.2 100mm/T2.1

Note:
1. Lenses not listed above are not tested and they may or may not work. We do our best to resolve any compatibility issue you find but firmware updates are by factory service only and there is a nominal shipping/handling charge.
