Overview

The Prakticar 135mm f/2.8 MC is a compact, M42-mount telephoto lens, a Korean-made copy of the East German Pentacon 135mm f/2.8 (Orestor formula, 5 elements/4 groups) but with a 6-blade diaphragm instead of 15. Optically, it is "pretty sharp" and focus is smooth, but it is "not exceptional" and lacks consistent sharpness across distances. Build and handling are typical of manual M42 lenses. It suits photographers seeking an affordable, compact 135mm for portraits or creative use, though alternatives may offer better consistency.
