This Pro Lens Mount Adapter from Fotodiox enables the use of M42-mount lenses on cameras with a Contax/Yashica mount. A simple device with no moving parts, it is made entirely out of durable brass with a stainless steel finish and accurately maintains infinity focus. It includes no optical elements to preserve the sharpness and clarity of your original lens. This manual adapter does not maintain automatic lens control between the camera and lens; aperture priority or manual shooting modes should be used, as well as stop-down metering for exposure control.

A: Yep!! Works fine!! You can zoom in on MF and use focus peaking!! Great lens!! Great cmera! Great combo!!

Q: 10. Will this allow focus to infinity? Thanks!

A: Yes it will. I'm using an old Osawa 35-105 Macro MC lens on a Canon XS and it works fine. Bear in mind, the lens will be a completely manual operation,only the camera metering will work. Best results will be with camera set to Manual. The adapter is a small price to pay to have some fun with an old favorite lens that was otherwise used as a paper weight.Good Luck!
