Nikon F25B manual Memo Holder, Setting the Film Speed

Memo Holder

A special holder is provided on the camera back for con- venient storage of information pertinent to the photo- graphy. A piece of paper or the end-flap torn from the film carton can be inserted to serve as a reminder of the film type, film speed and number of exposures.

Setting the Film Speed

The camera's exposure meter must be adjusted to the speed of the film in use to ensure correct measurement; thus, a film-speed scale (ASA graduations) and an index ring are provided on the finder. To adjust, lift the milled ASA film-speed index ring and turn it until the red index triangle is aligned with the ASA value for the film in use. The meter is sensitive across the fu II range of from ASA 12 to ASA 6400. The film-speed dial has two dots be- tween each pair of numbers for intermediate settings such as 64, 80, 125, etc.
