THREE IN ONE 



Perfection in a Photographic Lens is 

 possible only when 



Perfect Computation 



Perfect Grinding, and 



Perfect Mounting 



are combined in the same instrument 



The most perfect computation does not lead to perfect pictures unless the most 

 perfect mechanical devices are applied in the manufacturing. 



Highly polished surfaces are of no avail unless they are in absolute accordance 

 with perfect computation. 



A perfectly computed and perfectly ground and polished lens is not better than 

 a rectilinear when it is carelessly mounted. 



The triple alliance of perfect computation, perfect grinding, and perfect mount- 

 ing made for the 



GOERZ LENSES 



the high reputation they deservedly earned for themselves
