Using legacy lenses on Sony Alpha A7 / A7R

[jamie_robertson2]

<p>Hi folks,</p>

<p>I don't own any Sony cameras but I am getting a lot of enquiries from people who have the new full frame mirrorless cameras from Sony. They want to know if the existing lens adapters for the APS-C NEX cameras will work on the Alpha 7 or 7R and give full coverage of the larger sensor. My gut feeling is that they will not work but I would like confirmation from any of you that know for sure.</p>

<p>I've attached a picture of a current Leica M to NEX adapter as an example.</p><div></div>

<p>And here's another example. This time a Canon FD - NEX adapter...</p><div></div>

<p>I'm guessing/hoping that unless the adapter has an APS-C plate cutout in the adapter as the Sony A mount adapters for the Nex have, they should work. But I don't know for sure.</p>

<p>Thanks David. All the adapters I have seen have the full circular opening at the back. It is the flange distance that concerns me the most. I am wondering if the full frame cameras require the lens to be closer to the body.</p>

<p>From what I've read, NEX lenses can be directly attached to the A7's with the only downside being that it puts the 7 into a crop mode. So there doesn't seem to be an issue with flange distance.</p>

<p>These adapters work just fine.</p>

<p>Thanks guys, that is really good news.</p>

The flange distance for NEX and A7 is the same because the mount spec is the same. Those adapters should be fine,

unless their shape is such that some of the light path is obscured causing a vignette. You couldn't say with 100% certainty

but I'd be 95% sure those are all good on an A7.
