Olympus, (Zero Optik Rehoused) OM 50mm T2.2 Macro Lens (PL)

Olympus OM still photography lenses were announced in 1972, and are unique in that so many of the focal lengths (even the 21mm) are are all f/2, all cover full frame, and nearly all of them were designed by the same person: Yoshihisa Maitani. Since most of these lenses came from the mind of one person, it’s a very consistent set in more way than just maximum aperture. 

Optically Olympus OM lenses are sharp, with low CA. They have higher contrast due to their multi-coated optics, but they flare big, and beautifully. Bokeh has more texture than modern lenses. They are also quite small, and very lightweight. They are a very good balance between vintage and modern optics.
