Microplanar 4.5/100mm lens for microfilms and microphotography, hi-res, #63088
Microplanar is a lens with flat field of view, perfect geometrical aberrations correction, very good chromatic aberration correction. It covers full 35mm frame (24x36mm) easily (reference book says about 12x18 cm frame coverage, but I'd rather say 6x6 cm to be sure). Though LOMO named it's lens like Zeiss Microplanar, optical diagram is more like of Leitz Luminar.
This lens was included into delivery set of Russian microfilm stations. Good news is very long FFD (about 80mm), so it can be easily adapted to most old and modern systems, including reflex ones. The lens is perfect for low-power magnifications and reproductions. It offers 3x native magnification with 330 lpmm resolution in the center (150 lpmm on the edge).
Appearance is excellent. Only minor signs of use.
Mechanical condition is excellent. Aperture moves smoothly.
Optical condition is very good. No fungus, no scratches, no cleaning marks. But some dust inside, and some damage of coating layer on the front element (shouldn't affect image quality).
