The 35-135 mm Vario-Sonnar
®
 T
* f/3.3-4.5 lens 
from Carl Zeiss is a 3.8x zoom lens. Its superb 
image quality makes it another valuable addition to 
the existing range of Carl Zeiss Vario-Sonnar
®
 
lenses for the Contax
®
 SLR Camera System. The 
image quality is very good even at the shortest 
focusing distance of 1.2 m. 
This Vario lens has also been manufactured using 
the one-touch zoom design patented by Carl Zeiss, 
i.e. the same ring is used for focusing and zooming. 
The large focal range starting at 35 mm allows the 
use of this lens for almost all applications in 
architectural, landscape, portrait and sports 
photography.
Furthermore, the macro setting permits pictures to 
be taken down to a reproduction ratio of 1:4.
