I've got a ton of M42 lenses and this adapter works great. Very weighty and high quality.

Perfect fit with no give and lets me use 40+ year old lenses found in the attic. This is a dumb connector so it means NOTHING will be automatic, as long as you understand this before you buy you won't be disappointed.

Works perfectly on the Sony Alpha A6000 as it should.This attachment allows you to use the old M42 screw lenses with the modern Sony E-Mount cameras however bear in mind the auto focus will no longer work while the lens is attached and you will have to use the focus ring on the lens itself.Ive used it in conjunction with a Carl Zeiss Tessar 50mm and it has produced some lovely sharp photos.For the price of this unit and a second hand lens you have a very nice set up for very little money

The lens itself is well-made and surprisingly seems to perform better than the similar Dot Line adapter from B&H. However, just like the one from Dot Line, it has a flange on the inside of the screw mount which makes it fit improperly with my SMC Takumar f1.4 50mm lens. When fully attached, the aperture ring will not spin and the focus ring will become increasingly tight towards infinity focus. It also does not come with an allen key either, but that's not surprising given the price.That said, I will keep it to see if it works with my incoming Helios lens.

Perfectly fits a 135mm Pentax SMC Takumar lens to Sony a6000. All metal construction and no loose gaps .
