* f/1.4 - 85 mm

  

The 85 mm Planar

®

 T

* f/1.4 lens ranks amongst 

the best high-speed lenses presently available for 35 
mm reflex cameras. An outstanding feature is the 
excellent image quality even at full aperture. 
This feature results in special applications of the 85 
mm Planar

®

 T

* f/1.4 lens for discerning amateur 

and professional photographers. Owing to the fully 
utilizable speed, this lens is especially suitable for 
stage photography. Sporting events, outdoors and 

indoors, in twilight and floodlights are tasks for 
which the press reporter requires or desires a focal 
length which is slightly longer than that of standard 
lenses due to the object distance or for reasons of 
perspective. As regards portraits, another 
advantage is that the depth of field is low with 
photographs taken with the diaphragm fully open. 
Thus an unsteady and disturbing background is 
avoided and the portrait stands out clearly against 
the surroundings.
