Zenit MC 3M-5CA 500mm f/8

Pros: Good resolution, Lightweight, easy to maneuver even without stand. Robust and easy maintenance. Simple but reliable construction. Very cheap price in relation to the quality

Cons: Lack of tripod attachment but not so serious for the Pro listed earlier. With M42 adapter with tripod attachment ... no problem.

Opinion: After a primary mirror setup work that was too pressed by a metallic sealing ring, the telephoto lens became great. Before she was suffering from a deformation of the glass she did not allow it to give a sharp image. Testing showed a different focus on two orthogonal planes. A frequent problem with the Russian mirrors (500 and 1100 MTO) as the workers tighten the rings too much. It has a depth 'minimal field, like all catadioptric, but you just get used and find ways to make good photos. Complete with filters and purse, but without hood. Great in cases where photography can not be approached. Inserting extension rings can be used at less than 4 meters distance and with greater magnification.

Zeiss Jena Tessar 50mm f/2.8

Pros: From F4 onwards but without getting to exceed F11 very good sharpness. various tests made with other newly built objectives ... Regge confrontation despite ... A contrast sleeping less, due to less complete antireflection coating. The mechanical part is in old style Zeiss style.

Cons: Say .. A pinch of only TA disappointment.

Opinion: Beautiful in its aluminum livery. Mounted on a mirrorless ... from a special pleasure. I have also the older brother Sonnar 135 ... that is monstrous ... and together they are a pair magnifica.Consigliabilissimo especially if paid 30 Euros like me ... I arrived in good condition but a nice clean the lenses ... it regained 100%. The colors seem inecceppibile.Con a rollover ring or the rings allows macro superlative.Il vintage charm of Carl Zeiss. wonderful
