Underwater Photography Glossary
Traditional 35mm film cameras use 36mm x 24mm sized film (see "full frame"), like the Nikon FX or Canon EF format. Most DSLRs use smaller (roughly 24mm x 16mm) "cropped" image sensors (Nikon DX or Canon EF-S formats). Canon cameras have a 1.6X crop factor, Nikon cameras have a 1.5X crop factor. The crop factor describes the sensor's width ratio to a full-frame 35 mm sensor. For example, a 50 mm lens used on a sensor with a 1.6X crop factor would produce the field of view of an 80 mm lens (1.6 x 50 ) on a full frame sensor.
