Q: 2. I just purchased a Sony A7 from you. I have an NEX-7 so can use those lenses but I also have a large selection of various generations of Nikon lenses (vintages from my old F3 to current D800) that I would like to use on this body. What is the correct adapter. I see some from Metabones but they specifically indicate Nikon to NEX and not A7.

A: The Metabones Nikon G Lens to Sony NEX Camera Lens Mount Adapter is compatible with the Sony full frame E mount cameras such as the a7 and a7R. This adapter would be a good option for using your Nikon lenses on the a7 and NEX-7.

Q: 3. What's the outcome of using this adapter with Nikon DX lenses on my Sony A7s both in aps-c mode and full frame?

A: In APS-C crop mode, the image would have a 1.5x crop inside the camera, having the same view as if used on an APS-C camera. If used in full-frame mode, as DX lenses are designed for the smaller image sensor, it would have a black rounded vignette in the corner of the image where no light from the rear of the lens reaches the full-frame A7s sensor.

Q: 4. Do C-mount lenses cover the full frame of the Sony A6000 sensor, or is there vignetting?Thanks!

A: A C-mount lens used with this adapter on your A6000 will not encounter any vignetting.

Q: 5. Is ok to use in full frame a7s? No vignet in corner?

A: Being that this adapter takes full frame 35mm lenses, it will not cause vignetting when using the adapter on the A7S.
