75/1.5 Zeiss Biotar for Exakta

The later preset version (left) and the earlier manual version (right)

Zeiss made the 75/1.5 Biotar in many different mounts, but it is most common in Exakta mount. It was an extremely fast short telephoto, faster than most normal lenses of it's time. The later preset version is much more common than the earlier manual diaphragm version. Most have an aluminum barrel, but some of the earliest examples may be chrome over brass.
