The high-speed artist

The Distagon T* 2/28 ZF closes the gap in the line of 

high-end lenses for analog and digital SLR cameras 
because the jump in focal length from 35 mm to 25 

mm is too big for many demanding photographers. 
Modeled on current state-of-the-art lenses in this 

category, it features markedly improved optical 
quality. Thanks to the floating design, image quality 

remains almost consistent from the close-up range 
to infinity.  

These features make the Distagon T* 2/28 ZF ideal 
not only for atmospheric photos in weakly 

illuminated rooms, but also for attractive portraits 
from a close distance. With the aperture fully or 

almost fully open, you can use the low depth of field 
to make the main subject stand out slightly from the 

background without causing total background blur. 
The high image quality in the close-up range permits 

the application range of this lens to be extended to 

include still life photography of small objects.
