I'm looking for a reversing ring (for macro) that will work on my Sony a7 camera. The lens I have has a 49mm thread, so that part looks o.k., but I need to know which body mount this ring will work with—
1) the Alpha mount Sonys, OR
2) the E-mount Sonys like the NEX cameras or the new a7, or a7r, or a7s cameras?
I do understand that this type of ring doesn't communicate with the lens. Thanks for your help.
I would check metabones offerings as a place to start. As i think you need to go from a threaded 49 mm to FE mount. Make sure you are getting an adapter for a full frame sensor for your Sony A7 otherwise you maybe in APS-C sensor territory before you realize. Be careful. John
PS i assume that you are using and expect manual focus and no auto focus functioning
PPS Don't know about this reverse ring from adorama, might be worth a try, check their return policy first on such an item.
