EXPOSURE COMPENSATION ADJUSTMENTS

Adjustments for Focusing Screens

Light transmission properties vary somewhat with focusing screen type, thus occasionally requiring exposure correction to compensate for the combined effects of the lens/screen combination in use. The numbers listed in various blocks of the table on the opposite page denote the amount of correction necessary in f/stops. To adjust the camera's finder for the indicated f/stop cor- rection, lift and turn the ASA film-speed index ring until the ASA value for the film in use is aligned with the appropriate mark engraved on the ring. In the example figure shown, ASA 100 is aligned with the -Y:!mark to provide the correction required when using the Type C screen with the Nikon F2SB Photomic camera and the Fisheye-Nikkor 8mm f/2.8 lens, as indicated in the table. (When "0" is indicated in the table, no compensation is required.)
