IDEALS 



^ We are all working for an ideal — 

 aiming to do something better than has 

 been done before. In photography we 

 are peculiarly limited by the lens, our 

 most important tool; hence the necessity 

 for using the best, procurable. The 



BAUSCH & LOMB-ZEISS 

 TESSAR LENSES 



combine all those qualities most, de- 

 manded by the photographer: great 

 light-gathering power, resulting in great 

 speed; sharp definition, extending over 

 the entire plate; uniform illumination, 

 producing brilliant negatives. 

 €| The series includes the Tessar lib 

 and Ic. Send for new illustrated circu- 

 lars showing their possibilities. 

 Cf Our lenses are identical in every respect 

 with the famous Zeiss products — we use the 

 same glass and formulae, the same means and 

 methods of manufacture.
