A M42 Classic lens, 30mm f3.5 Pentagon previously the Meyer-Optik Gollitz Lydith. The M42 Pentax, Praktica, Zenith mount is easily adaptable to current mirrorless bodies via inexpensive adapters and I have successfully used it with a Nikon Z series using Manual focus with focus peaking and manual exposure with the benefit of auto ISO.
The lens is in good condition with clear glass, no haze or fungus. The focus action is smooth and is quite good for close ups with a minimum distance of about 11". The aperture is the manual close down pre-set type and works well.
The Z6 camera body and M42 - Nikon Z adapter is for illustration and is not included.
Demo grab shots taken with the Z6 at f8.
