- 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.
- aperture priority
- autofocus
- auto exposure
- center-weighted
- 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.
- film advance
- 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.
