Voigtländer Zoomar 36-82mm T3.1. This is one of the oldest zooms ever designed for commercial still photography for the 135 format (Full Frame 36x24mm). It was released in 1959, and was incredibly advanced for its time. The images it makes are still impressive today.

Crucial for any cinema zoom lens, this lens is parfocal. It is sharp on center, with subtle fall-off towards the corners. The lens has surprisingly low chromatic aberration for such an old lens, and has minimal focus breathing.
