The outstanding advantage of the Telephoto Lens is that 

 of allowing the photographer to keep some yards from his 

 subject, and yet permitting him to obtain large direct pictures. 



THE NEW ADON TELEPHOTO LENSES, 

 working at apertures of f/6, f/4'5 and f/10 are particularly 

 suitable for this work, and permit of subjects such as that shown 

 above, being readily obtained. Birds on the wing can be 

 snapshotted and scientific data obtained. 



A visit to the Dallmeyer Show Rooms at 25, Newman 

 Street, Oxford Street, W., would be found of great interest.
