Movie cameras are selected based on the director's individual approach to the film. Differences can include film type, digital or non-digital, shutter speed and lens selection.
The 35 mm camera is the most common type of camera used to film movies. This camera records images onto regular film, and can be used in a variety of fps (frame per second) speeds.
Some directors choose to shoot their movies using digital cameras. However, such cameras often record footage onto digital video tapes rather than simply storing it on a hard drive.
Digital cameras have received criticism for being too sharp to give the familiar look of regular film. Lighting has to be absolutely perfect when filming with digital cameras, or many mistakes may need to be edited out.
More important than the type of camera is the lens used within the camera. Examples of common lenses include telephoto, wide-angle, anamorphic and spherical.
