K&F Concept Lens Mount Adapter with Tripod for Canon EOS EF, EF-S Lens to Sony DSLR Camera Camera Body
SKU: KF06.263
The adaptor itself seems to work fine. I've used it with lenses like the Helios 44M 58mm and Helios 28mm wide-angle with much success. However after shooting with it for several days, I've noticed maybe a dozen fine metal particles covering my A7ii's sensor. I can't be certain whether the particles came from a lens or the adaptor itself, but it might be a good idea to leave one of these adaptors on each M42 lens you have, or purchase a more expensive one that won't wear.

Does what I expected it to do. I have just bought my first full frame Sony A7. My last camera being a now very old canon 350d. At the moment I can not afford to buy a lease that covers that 200mm range so need to use my old Tamron lense. Manual focus and no control of aperture but does seem to work with the peaking function. But for the price does what I needed it to do.

Excellent adapter, does exactly as it should. I can now use my selection of M42 lenses on the Sony A7ii the way they should be used.

Bought to use vintage manual M42 lenses adapted to EF on my Sony A7iii. The K&F Concept EF to Nex adapter works perfectly. It has a nice firm connection to the camera body and all of my EF adapted lenses fit very well. Lenses focus as they should.Worth £25 to be able to use vintage lenses on a digital body.

I waned this to test my old glass on a Sony FS5 camera and it worked perfectly.
