Please note that "all purpose" in this context means that it's suitable for purposes of photography requiring focal lengths of between 18 and 140mm

The 4x5 variety is on a thin base and is prone to curling

Olympus Zuiko 50mm f2 Auto-Macro brand_K&F Concept Please note that "all purpose"The Olympus Zuiko 50mm f2 Auto Macro is a great lens for macro and everyday use this is a fast 50mm no matter what the occasion. In excellent cosmetic condition, with only very minor wear. Focusing is smooth, and glass has only light dust which will not affect imaging. Diaphragm is snappy and clean, though the stop down lever action has a tiny squeak. A very nice lens in good shape.
