Carl Zeiss: C Biogon T* 2,8/35 ZM
By Shutterbug Staff
 May 9, 2008 — 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:
