T* f/3.5-4.5/70-200 lens by Carl
Zeiss is a convenient tele zoom for the Contax N
autofocus SLR system.
It is designed with the motives and needs of the
demanding travelling photographer in mind. So it has
a durable precision barrel, but is relatively lightweight
and small, especially in transport mode. Filters with
67 mm thread can be used at any focal length without
vignetting.

T* f/3.5-4.5/70-200 lens produces
high image quality which is available at all focal
lengths even at maximum f-stop in the center of the
image. To achieve this high level of performance,
Zeiss used optical glass types with anomalous partial
dispersion for several lens elements.
The Carl Zeiss T* multi-layer anti-reflex coating of lens
surfaces, combined with stray light absorbing
mechanical elements in the lens barrel, enable brilliant
images with vibrant colors.
