The Sekonic LC-2 light meter is s selenium type meter. Made in Japan in 1957. It is small & clips onto an accessory shoe on top of the camera. The company’s roots apparently trace back to June 1941 and officially established as Seiko Electric Industries Co. in 1951 based in Toshima, Tokyo. Its first exposure meter was the Sekonic P-I and later in 1957 introduced the LC-2 version.

First set the inner ring to ASA, there is no provision for DIN with ASA settings from 8 to 1600. Point the camera with light meter in direction to photograph. The red needle will move into a zone. The zones are from 1 to 7. Transfer this number to the outer ring cut away.

How to check if the meter is reasonably accurate :
– Make sure that the pointer is reading zero with the cell covered with your hand. If not, adjust with the screw on the base.
– Point the meter to a clear north sky at any time between 10 A.M and 2 P.M.(Northern hemisphere) Southern sky (southern hemisphere) There must not be any clouds or haze.
– This should translate to f/16 at 1/100 or LV 15, with film speed set to ASA/ISO 100.
