The FotodioX Contax/Yashica Lens Adapter for C-Mount Camerasis a high quality adapter that allows you to mount a Contax/Yashica mount lens to a C-mount camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment of the lens to the adapter. Additionally, this adapter features a built-in aperture control for determining the amount of light let into your camera.

Although the lens will fit physically, automatic lens control and functions will not operate correctly while using this adapter. You can utilize aperture priority mode in combination with stop-down metering for automatic exposure control on your camera.

Q: 1. I have a Contax NX with two Zeiss lens: 1) T* Planar 1.4/50mm, and 2) T* Vario-Sonnar 3.5 - 4.5/70-200mm. Will this adapter work with these lens to a Canon EOS 7D?

A: The Contax NX has the Contax N-Mount, which is different from the Contax/Yashica (C/Y) mount. Unfortunately, this adapter would not be compatible with your lenses, nor do we have an adapter that would mount N-mount lenses on a Canon EOS body.

Q: 5. I’ve read Contax G system’s AF would always return the focus to it starting position. Is this the case with this adapter? I mean, is there a spring in the lens that returns the focus back or once this adapter is used the lens becomes a manual lens like Leica for example? Also, does it have a hard stop at infinity or one can focus past it?

A: The lens adapter is a manual one. It does not transfer any electronics of the lens. The lens will not have autofocus and like the adapter it will be manual only.
