Excellent adapter that re-invents vintage mounts for mirrorless cameras
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!
