Abstract

1,176,546. Lens caps. NIPPON KOGAKU K.K. July 31, 1967 [Aug. 3, 1966], No.35122/67. Heading G2A. A removable lens cap for a single lens reflex camera having a through-the-lens metering system, is made of a translucent material having a light transmissivity of about 18%. The cap may be either flat or hemispherical. By using such a cap, the camera meter, normally used as a reflected light meter, may be used as an incident light meter.
