Solid and resistant, it's inside with my Sony Alpha and I'm oblivious to the inside of the M42 without a problem

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!

This adapter worked perfectly! All I had to do was allow my camera to take a photo without a lens (the computer in the camera can't recognize that there's a lens on) and I was able to take beautiful pictures with my 50 year old 55mm and 28mm primes salvaged from an old film camera. Super impressed with this adapter, I bought one for my old Canon lens too. Definitely recommend!

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.

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!

Saved me from buying expensive lenses.
It fit perfectly and worked flawlessly for my trip to Italy for a month.
I would buy from this manufacturer again given the quality and versatility with my automatic lens features without doing much research for competitors.

The products are very economical and have the credo that they have the best possible ability to create a product that is always robust and lightweight at a steady pace

La bague fait ce qu'on lui demande. I'll retire to myself for the fact that I'm able to realize the mount of my memes for the indication of the outcome and the focus of my objects so that it's safe and not on the coté.
