The LMA-M42_NK adapter is made of black anodized aluminum and allows the use of M42 thread lenses (from Zeiss, Pentax, Praktica, Mamiya, and Zenit) and macro accessories on NIKON F cameras (35mm and DSLR).

Since the adapter does not have electronic communication between the lens and the camera, automatic focus is not available. The user will need to manually control the aperture and focus of the lens.

This adapter does not focus to infinity.
