Expanding your horizons 

This full-frame lens is the direct successor to the 

legendary Distagon 2,8/21. It has been redesigned 
on the basis of the proven design and equipped with 

modern, environmentally friendly types of glass.  
 

It continues to set standards in terms of image 
quality and color correction. Glass types with 

abnormal partial dispersion and high refractive index 
provide the foundation for photos without color 

fringes right to the edges, even with an f/2.8.  
Carefully designed optics, the internal mechanical 

design of the barrel, and the use of T* coatings on all 
lens element surfaces have resulted in very good 

reduction of glass-to-glass and glass-to-film 
reflection. 

A precise mechanical design, a good feel and 
smooth function of the focusing ring helps you in 

arranging your photos. Internal focusing and the 
0.22 m close range enable high-quality photos with 

unusual perspectives. 
The use of standard screw-on filters and the lens 

shade included in the delivery package expand the 
application possibilities of this lens.
