For example, a 28 mm lens delivers a moderately wide-angle FOV on a 35 mm format full-frame camera, but on a camera with a 1.6 crop factor, an image made with the same lens will have the same field of view that a full-frame camera would make with a ~45 mm lens (28 × 1.6 = 44.8). This narrowing of the FOV is a disadvantage to photographers when ...
This means the crop factor for most film-based Hasselblad cameras (based on diagonal angle of view) compared to "full-frame" 135 is 0.54; for example, a V system lens with a focal length of 80 mm would have the equivalent coverage of a lens with a focal length of approximately 45 mm on a 135 film camera.
Digital sensors are usually smaller than 35 mm film, and this causes the lens to have a narrower angle of view than with 35 mm film, by a constant factor for each sensor (called the crop factor). In everyday digital cameras, the crop factor can range from around 1, called full frame (professional digital SLRs where the sensor size is similar to ...
The first full-frame DSLR cameras were developed in Japan from around 2000 to 2002: the MZ-D by Pentax, [26] the N Digital by Contax's Japanese R6D team, [27] and the EOS-1Ds by Canon. [28] Nikon has designated its full frame cameras as FX format and its smaller sensor interchangeable-lens camera formats as DX and CX.
On a crop camera with APS-C/H size sensors, it only yields a cropped circular and full-frame image. A zoom lock is included which avoids leaving the focal length range of full coverage on crop sensor cameras. Nikon AF-S Fisheye Nikkor 8–15 mm f /3.5–4.5 E ED – designed for full-frame and FX cameras, this lens behaves identically to the Canon.
Equivalent depth of field can be calculated the same way using the crop factor. [3] For example, a 50mm f/2 lens on a 2× crop factor Micro Four Thirds camera would be equivalent to a 100 mm (= 2×50 mm) f/4 (= f/(2×2)) lens on a full-frame digital SLR in terms of field of view, depth of field, total light gathered, [4] and diffraction effects ...
The first digital rangefinder camera commercially marketed was the Epson R-D1 (released in 2004), followed by the Leica M8 in 2006. [16] They were some of the first digital lens-interchangeable cameras without a reflex mirror, but they are not considered mirrorless cameras because they did not use an electronic viewfinder for live preview, but, rather, an optical viewfinder.

Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its background.
