The CARL ZEISS 



Series lc Tessar 



is the best portrait lens made. 

 Having a perfectly flat field and 

 giving microscopic definition, it is 

 particularly adapted to ultra- 

 rapid photography with a focal 

 plane shutter. 



With smaller apertures it gives 

 the same depth of focus and in 

 fact accomplishes the same re- 

 sults as the slower anastigmats.

 alogue and further information
