38mm · f/8
The Carl Zeiss Jena DDR Dokumar 38 mm f/8 lens, originally from a Dokumator repro unit, offers very good field sharpness uniformity, as noted by allphotolenses.com. Its fixed aperture and specialized design limit versatility, but it suits reprographic or macro work where even sharpness is critical. Build is typical for industrial optics, with no mention of handling issues. It is not ideal for general photography due to its slow aperture and fixed focus.
