- auto exposure
- Bay I
- center-weighted
- click stops
- cable release
- coated
- contrast
- Compur
- Copal
- 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.

- focal plane - The flat plane onto which a lens focuses its image.
- frame counter
- GOST
- large format - A film format larger than medium format, in which negatives are loaded one at a time rather than in rolls.
- leaf shutter
