The F2 Photomic combines a brilliant eye-level prism finder with the through-the-lens "center-weighted" meter system for quick, accurate and reliable exposure control, even in difficult lighting situations. It is powered by two silver oxide batteries housed in the camera baseplate and coupled to both lens aperture and shutter speed controls. Complete exposure data is visible beneath the picture area: meter needle, indicating correct, over or under-exposure, plus selected aperture and shutter speed setting. The meter needle also appears in a window on top of the Photomic housing. Using the meter involves no added operation - the on/off switch is activated by the film transport lever.
The F2 Photomic offers an uncommonly wide metering range, from EV 1 to EV 17 (e.g., 1 second at F/1.4 to 1/2000 at F/8 with ASA 100 film, using the 50mm F/1.4 lens). It can be set for film ratings from ASA 6 to 6400 and couples to Auto-Nikkor lens apertures from F/1.2 to F/32, as well as all shutter speeds. A special feature of the F2 Photomic is the eyepeice ready-light for use with the Nikon Electronic Flash Unit. The eyepeice accepts various accessories (eyepeice correction lenses, right angle finder, eyepeice magnifier, rubber eyecup and Photomic illuminator),
