Vario-Sonnar® T* 4.5/45-90 for the CONTAX® 645The Vario-Sonnar® T* 4.5/45-90 lens is an all-round autofocus lens for the Contax 645. It is particularly well-suited for demanding photojournalistic work, where prints may be enlarged to poster size with fine details which cannot be reliably captured with 35 mm cameras.

Preferred use: demanding photojournalistic work, weddings, travel, street photography, people, industrial and forensic documentation. SpecificationsCat.
