Well made adapter maybe could do with being marked to show which side is for camera and which for lens, would be quicker if swapping, but its only a choice of two sides.

UPDATE: Since my D750 camera was not on the list for this adapter, I wrote to you earlier and you clarified that it would work. Yes, it WILL connect the lens, but the aperture ring won't move. I have two old Tamron lenses that date back to the 1970's and used on my Pentax. I tested my two lenses and I have to return it.

Although there is not much to this item it fitted properly, and was well finished. I used it to attach a 500mm mirror lens on a Nikon D700. The lens being fixed aperture and manual focus the only requirement was to fix the lens to the camera. Using the camera on Aperture priority exposures were correct and focusing using the rangefinder indication in the viewfinder was straightforward.

works exactly as described and only bought it to try my old Tamron lens for my old 35mm yashica on my new Nikon D3200.So it works.
