Convertible Protar
Series Vila
SPEED F: 6.3- F: 7.7
A truly convertible lens made up of highly corrected single elements, which need no
stopping down as they cover perfectly at full aperture.
With the Protar Vila you can make two or three image sizes from the same view
point — according to the combination of lens elements you select.
Additional combinations can be purchased at any time, forming sets with a wide
variety of focal lengths. One shutter takes all combinations, saving the trouble-
some multiplication of flanges, adapters, lens boards, etc.
Ask your photographic dealer to show you one of these lenses, or write us for
specific information regarding lens for your camera.
