Canon A-1 with a FD 50/1.8 Viewfinder of a Canon A-1. The right number is the current F-number (1.8), meaning that the aperture is fairly wide open. The left number (45) indicates the approximate shutter speed of 45 −1 s (the camera can select odd shutter speeds, but does not display them)
The camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches the film or sensor (the exposure). Exposure value (EV) is a quantity that accounts for the shutter speed and the f-number.
A system for indicating correct exposure in which the shutter speed and f-number are related arithmetically. [4] [15] EVF: Electronic viewfinder. The through-the-lens view is displayed on a miniature solid-state screen, rather than on an optical screen or view. [2] EVIL: Electronic viewfinder interchangeable lens camera.

Shutter speeds range from 30 seconds to 1/8000 of a second in all exposure modes. A non-timed bulb speed is available. Flash X-sync is available up to a shutter speed of 1/250 of a second. There are 14 custom functions to change the way the camera operates, which set options like exposure steps and mirror lock-up.
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
