Solidly built, snugly fitting and well-engineered adapter that lets you use classic Contax/Yashica lenses on a Canon R-mount camera. There are no electronic connections, so focus is manual - not a problem for mirrorless cameras with focus peaking and an electronic viewfinder. Use Aperture Priority mode and the camera automatically adjusts Shutter Speed and/or ISO for a proper exposure. I previously used first-generation focus-chip adapters with a DSLR. They worked, but only with a lot of finicky calibration (so you needed one adapter for each lens), and were very fidgety to mount. This new adapter for mirrorless cameras is a major improvement: It's purely mechanical (no electronic connection), but K&F nicely re-invented the mounting mechanics on this adapter (same for K&F's Nikon version) with a button you hold down to quickly twist lenses in and out. It's like having the mirrorless Contax camera that never existed! So much easier on lenses and on your patience. Great piece of kit that smoothly integrates vintage lenses into the latest generation of cameras. Couldn't be happier!

Very nice snug fit on my Canon R6. No adjustment necessary to align up the f/stop markings on the M42 lenses. Everything is manual settings and that's perfect. Just set up your in camera setting for focus peaking and your off to making some great photos with the old amazing M42 lenses.

This is my third adapter from K&F Concept as I shoot with a variety of different camera brands and I need to adapt my Pentax PK lens to them. Quality is excellent and the adapter fits my camera perfectly. Very pleased with these adapters and the price is easy on the wallet!
