Camera Work: A Photographic Quarterly (1909 (Heft 26))

Bausch & Lomb
New Compound Shutter

PLACES at the command of hand camera users an
ally of the speed lens.
flAn automatic and setting shutter combined, it permits
both bulb and time exposures to be made automati-
cally, while speeds of from one second to 1-250 second
can be given automatically when the shutter is set.
flThe
mechanism is precise and accurate and little
liable to derangement.
<JLight in weight and handsome in appearance.

The Compound Shutter and a Bausch & Lomb-Zeiss Tessar
form an ideal equipment for the hand camerist.
