Great lens adapter. Wasn’t sure it it would fit my A7iii but it does. It’s a slightly snug fit but does go in. Feels very solidly built and is perfect for my Nikon fit manual focus lens. It does have apaerture adjustment on it but you won’t know exactly what aperture you are on, but I’ve got an aperture ring on my lens so it’s fine.

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.

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.
