BOSS' POETEAIT AND VIEW LENSES. 



QUICK-ACTING C.D.V. LENSES. 



These Lenses give very rapid results with brilliancy and exquisite definition. 

 To obtain the best results it is desirable to use the No. 3 when the Studio exceeds 

 20 feet in length. 



BRILLIANT DEFINITION AND GREAT RAPIDITY. 



3179 RAPID CABINET LENSES. 



These Lenses have all the sharpness and good qualities of the Portrait Lenses^ 

 but, having a natter field, give better marginal definition. To obtain the best 

 results it is desirable to use No. 3 when the Studio exceeds 20 feet in length. 



BRILLIANT DEFINITION AND GREAT RAPIDITY. 



3180 IMPROVED PORTRAIT LENSES. 



These Lenses give all the sh'arpness that can be optically obtained. They are 

 admirably adapted for Half-lengths and Sitting Figures ; but for Full-lengths the 

 ' Cabinet " and " Carte " series give a flatter field.

UNIVERSAL LENSES. 

 For Groups, Portraits, or Studies in the Studio, Interiors, Copying, &c, 



The "Universals " possess optical properties between ordinary Portrait Lenses 

 and the Bapid Symmetricals ; but are not equal to either of these Lenses for their 

 special work. They are, however, fair substitutes for both in cases where one Lens 

 only is desired. 



Larger sizes to order.
