SOM Berthiot Lenses

SOM Berthiot continued to improve the design of the Pan Cinor lens throughout the 1960s. The built-in reflex viewfinder on later lenses included split image or coincident image focusing aids that increased the versatility of non-reflex cameras. At the same time, the 40 RX and 85 Compact were designed specifically for use with reflex H models.

In cooperation with Paillard, SOM Berthiot designed the lenses for the Bolex Zoom Reflex P1, P2, P3 and Zoom Reflex Automatic P4 cameras. These were built-in lenses which offered reflex viewing and, in some cases, visual focusing aids.
