Carl Zeiss: C Biogon T* 2,8/35 ZM

The latest member of the ZM lens family is the C Biogon T* 2,8/35 ZM. The "C" in the title indicates another outstanding feature: rather unusual for a lens of this performance class, its moderate speed of 1:2.8 permits an exceptionally compact construction. The symmetrical Biogon construction with 7 lens elements in 5 groups allows for practically distortion-free images.

The ZM lens series from Carl Zeiss is suitable for cameras with M-bayonet. As with the other lenses in this line, the C Biogon T* 2,8/35 ZM features a robust all-metal frame and a precise, noticeable click in 1/3 aperture stops.

Delivery of this lens is scheduled to begin in mid 2008:
