The Carl Zeiss Tele-Apotessar® T* 4/350 lens is
specially designed for the Contax 645 medium format
autofocus camera system.
Being a highly corrected optical tool for the demanding
medium format photographer it incorporates 9 lens
elements in 8 groups, several elements being made of
fluor crown glass to correct chromatic aberrations
exceptionally well. Due to elaborate stray light baffling
techniques and specially developed absorptive surface
treatments, internal suppression of flare is on an
extremely advanced level. Stunningly brilliant photos
with true-to-life color rendition and vivid saturation are
the result.
The Tele-Apotessar® T* 4/350 lens comes with a
rotatable tripod collar, and Carl Zeiss recommends to
use a good tripod in order to bring the full optical
potential of this lens to film. Filter thread is M 95,
non-rotating.

Utilizing internal focusing optics and autofocus drive
motors in the lens, not in the camera body, the new
lens focuses as close as impressive 1.9 meters in front
of the film plane, 1.5 meters from the front lens
element. This enables the photographer to tightly fill
the fame with a child's face at a magnification of 1:4.
The level of correction is so high that the lens can be
successfully used wide open. So the photographer can
use selective focus in a very pronounced way. The
Tele-Apotessar® T* 4/350 lens comes with the
Mutar® 1,4x T* converter, building a powerful 5,6/490
mm lens. This optic expands the capabilities of the
Contax 645 system considerably.
