When calculating the effective focal length, it is important to take into account the image format a camera uses. For example, many digital SLR cameras use an image sensor that is 2 ⁄ 3, 5 ⁄ 8, or 1 ⁄ 2 the size of a 35 mm film frame. This means that the 35 mm frame is 1.5, 1.6, or 2 times the size of the digital sensor.

Perspective distortion. Simulation showing how adjusting the angle of view of a camera, while varying the camera's distance and keeping the object in frame, results in vastly differing images. At narrow angles and long distances, light rays are nearly parallel, resulting in a "flattened" image. At wide angles and short distances, objects appear ...
Telecentric lens. Bi-telecentric lens with 208 mm diameter front element and a C-mount camera interface. A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance ...
“Tom’s feedback was, ‘I love the idea, only we’re not doing a stuntman in a balaclava. I’m going to be the one who jumps off the roof, and I’m going to be the one who drives through ...

The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.

The usual frame size of 35mm still cameras is 24×36 mm, however half-frame cameras typical use an image area of 18×24 mm. One net result of this is that a roll of film can typically contain twice the number of exposures as in a full frame 35mm camera (that is, a roll that is nominally 36 exposures allows 72 in the half-frame format).
