A Canon 7 mounted with a 50 mm lens capable of f /0.95 A 35 mm lens set to f /11, as indicated by the white dot above the f-stop scale on the aperture ring. This lens has an aperture range of f /2 to f /22. The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system ...
Increasing f-stop decreases the aperture of a lens. In photography, stopping down refers to increasing the numerical f-stop number (for example, going from f / 2 to f / 4), which decreases the size (diameter) of the aperture of a lens, resulting in reducing the amount of light entering the iris of a lens.

Electronic viewfinder interchangeable lens camera. See also MILC, mirrorless interchangeable-lens camera. [16] Exif: Exchangeable image file format. A standard format for tag data in digital camera files. [10] f: f-number, f-stop. The numerical value of a lens aperture. The ratio of the focal length of the lens divided by its effective aperture ...
Aperture mechanism of Canon 50mm f/1.8 II lens, with five blades. Though as early as 1933 Torkel Korling had invented and patented for the Graflex large format reflex camera an automatic aperture control, [14] not all early 35mm single lens reflex cameras had the feature.
Many digital cameras have a display setting and possibly a physical dial whereby the photographer can set the camera to either over or under expose the subject by up to three f-stops in 1/3 stop intervals. Each number on the scale (1,2,3) represents one f-stop, decreasing the exposure by one f-stop will halve the amount of light reaching the ...
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.
For example, the photographer may prefer to make his sunny-16 shot at an aperture of f /5.6 (to obtain a shallow depth of field). As f /5.6 is 3 stops "faster" than f /16, with each stop meaning double the amount of light, a new shutter speed of (1/125)/(2·2·2) = 1/1000 s is needed. Once the photographer has determined the exposure, aperture ...
Its intent was to simplify choosing among equivalent camera exposure settings by replacing combinations of shutter speed and f-number (e.g., 1/125 s at f /16) with a single number (e.g., 15). On some lenses with leaf shutters , the process was further simplified by allowing the shutter and aperture controls to be linked such that, when one was ...
