Ever since I was in film school most professionals would say how important the glass you shoot with is more important than the camera or format. I’ve always held on to that idea even when shooting with a crappy kit zoom. Sometimes you just need a 300mm and the only one available is, well, embarrassing. Anyway I remember shooting with Pentax 6X7 SLR cameras back in school and they had these beefy lenses to cover the medium format. I was thinking about those lenses and sure enough Zeiss Jena, the East German lens maker made lenses for the commie version of that camera and others with the same mount. So after a little looking I took the plunge and sprung for a zebra 120mm Biometar 2.8. Of course the Chinese will make an adaptor for every mount, so we’ll see what this lens has to offer photography and cinema on a 5DmkIII. The later Jena lenses offered an MC or multi-coated lens and these look more like the leica R lenses, at least from the outside.
