Using this to adapt a Zeiss planar 50.7 on a lens turbo II to a NEX 6.There is no play between the adapter and the camera mount which is a issue on my chrome-plated brass copper Contax adapter ring. Although this is made of lighter material, (aluminum maybe?) this adapter still has a solid build and it works better, I cannot said anything durability for this particular item but I have half a dozen of various adapter rings before, none of them have had any issue. I would recommend this to people who don't need AF confirm function.

Well manufactured, all metal. Fit is excellent and there is no play once a lens is mounted. Recommended.
