Moritat Posted August 11, 2017 Share Posted August 11, 2017 I have an A6000 which I shoot with old Contax Zeiss and Nikon AIS manual lenses. I was considering the purchase of one of Sony's full frame A7 models. My plan was to rent one of these cameras and check it out, but I have a question. I've been using Fotga brand CY-NEX and Nikon-NEX adapters to use these lenses on my A6000. Can I use these same adapters on a full frame A7* camera without the picture being reduced to crop mode? I'm fairly certain these would work fine, but I wanted to be sure before renting the unit. Thanks in advance for responses. Link to post Share on other sites More sharing options...

a6k Posted August 13, 2017 Share Posted August 13, 2017 I don't know about the crop issue but you are moving from e mount to a mount so you will need different or additional adapters. Link to post Share on other sites More sharing options...

addicted2light Posted August 19, 2017 Share Posted August 19, 2017 No new adapters needed, like Username already correctly pointed out, and Contax-Yashica and Nikon glass will work wonderfully on the full frame bodies (I use both brands on the original A7r, and assuming you haven't got a lemon in the first place, these "old" lenses are super sharp) Link to post Share on other sites More sharing options...
Cheatah Posted August 28, 2017 Share Posted August 28, 2017 I am using adaptors for a quite number of my C/Y Zeiss and other glasses, and for some medium format glasses on my A7 and A6000, but because of the weight, I have replace the flimsy Sony bayonet rings with more stable rings from Fotodiox. Everything works fine now! My recommendation, don't buy the very cheap adaptors, buy the better quality! Link to post Share on other sites More sharing options...
snapaway Posted November 19, 2017 Share Posted November 19, 2017 ` If they're just empty tubes with no glass in them then there will be no problems. ` Hi, my adaptor got glass inside and the a77 prompt some message which i could not proceed to use it manually. What's the next move? Is there a certain settings that i have to change? Link to post Share on other sites More sharing options...
nomad Posted November 22, 2017 Share Posted November 22, 2017 You need to tell the camera in the menu that you want to shoot "without" lens. But you'll be disappointed with an adapter with glass inside (if it's not a SpeedBooster by Metabones). Link to post Share on other sites More sharing options...

I s there a certain settings that i have to change? You are adapting SLR-mount to SLR mount and thaz a bad idea unless you just make small images for web pages. My reference to "glass" was in the context of THIS THREAD which is about adapting SLR-mount lenses to APSC bodies. In such a context, the glass is an image compressor ... you can google "Metabones SpeedBooster" to read about that. OTOH, the glass in you adapter is not an image compressor but merely a focus adjuster, the exact opposite of a "close up lens" cuz the thickness SLR-to-SLR adapters causes adapted lenses to focus to near-distances-only if the glass is omitted. IOW such an adapter functions as an extension tube as well as providing conversion from one SLR mount to another. It's all about the flange depth of the body, which differs slightly from one brand to another [ google "flange distance" ]. Nikon lenses adapt to Canon bodies without need of glass, which by definition means the reverse is impossible [assuming that one expects normal focusing abilities in all cases].

Guest Jaf-Photo Posted November 24, 2017 Share Posted November 24, 2017 If an adapter to A-Mount has glass in it, it means the flange distance is too great. That means you'll only have close focus ability without the glass. Medium format lenses generally have longer flange distance, which means you can use them on A-Mount with a normal spacer adapter without glass. What the glass does is generally to ruin the optical properies of the lens you are adapting by placing an alien piece of glass in the path of the light. So, it's pretty pointless if you do it for the quality of the lens. Link to post Share on other sites More sharing options...
