50mm · f/2.8
The Steinheil München Cassar S 50mm f/2.8 is a tiny, polished steel lens with knurled grips, over 70 years old and likely uncoated, leading to heavy ghosting, flare, and a soft focus look. It is capable of very nice results, especially in black and white, and is considered not bad for a simple triplet. Its diminutive size suits small cameras like the Pen F with an adapter. Best for photographers seeking a vintage, soft-focus aesthetic and who embrace its optical flaws.
