This is a growing glossary of common camera terms. Feel free to add items that aren't listed.

  • 35mm a film format with frames measuring 24mm x 36mm on a roll of film wound into an easy-to-load cassette
  • aperture - an opening in a lens that limits the amount of light passing through it
  • coupled rangefinder - a rangefinder that provides a focusing aid which is "coupled" to the focus adjustment on a lens
  • depth-of-field - the range of distances (from near to far) within which a scene will be considered to be "in focus"
  • diopter - an optical adjustment that allows someone to adjust the viewfinder's magnification to their vision
  • f-stop - the measure of the aperture setting on a lens
  • field of view - the diagonal measure of the part of a scene that is visible with a given lens
  • flash sync - the manner by which a flash is fired while the shutter is open
  • focal plane - the flat plane onto which a lens focuses its image
  • large format - a film format larger than medium format, in which negatives are loaded one at a time rather than in rolls
  • lens - one or more glass elements used to focus an image onto the focal plane
  • light meter - a device that measures light to determine the proper exposure settings for a scene
  • medium format - a film format larger than 35mm but smaller than large format (typically 120 film) wound onto spools
  • mirror lockup - a feature on some SLRs that allows the reflex mirror to be locked in the up position to eliminate vibration
  • optical axis - the straight line which passes through the centers of curvature of the lens surfaces
  • parallax - an effect in photography where the image seen in the viewfinder is not the same as the image seen through the lens
  • parallax correction - a viewfinder adjustment to correct the effects of parallax
  • point-and-shoot - camera designed to eliminate the user's need to make focus and exposure settings
  • QL - a Canon designation for film cameras using their "quick loading" feature
  • rangefinder base - a measure of distance between the viewfinder and rangefinder windows on a rangefinder camera
  • shutter release - the mechanism (usually a button) that causes the shutter to open and close
  • SLR - single lens reflex
  • TLR - twin lens reflex
  • toy camera - an inexpensive camera usually made almost entirely out of plastic
  • TTL - through the lens
  • viewfinder - the part of a camera you look through when composing your shot
