Along with the other Sekor CS primes, also the CS 1.4/50mm is an extremely small and well made lens. Compared to modern 1.4/50mm or 1.4/55mm behemoths such as the Zeiss APO Distagon 1.5/55mm (Otus) it feels tiny, comparable in size to the Olympus Zuiko 1.4/50mm or the differen versions of the Asahi 1.4/50mm lenses.
