  2. Image sensor format - Wikipedia

    en.wikipedia.org/wiki/Image_sensor_format

    Although the most common medium format film, the 120 roll, is 6 cm (2.4 in) wide, and is most commonly shot square, the most common "medium-format" digital sensor sizes are approximately 48 mm × 36 mm (1.9 in × 1.4 in), which is roughly twice the size of a full-frame DSLR sensor format.

  3. Optical format - Wikipedia

    en.wikipedia.org/wiki/Optical_format

    Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor.The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube (an "old-fashioned" TV camera).

  5. APS-C - Wikipedia

    en.wikipedia.org/wiki/APS-C

    Drawing showing the relative sizes of sensors used in most current digital cameras. Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter.

  6. Micro Four Thirds system - Wikipedia

    en.wikipedia.org/wiki/Micro_Four_Thirds_system

    The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film. [4] Its area, ca. 220 mm 2 , is approximately 30% less than the APS-C sensors used in other manufacturers' DSLRs ; it is around 9 times larger than the 1/ ...

  7. Crop factor - Wikipedia

    en.wikipedia.org/wiki/Crop_factor

    A 50 mm lens on an APS-C format (crop factor 1.6) images a slightly smaller field of view than a 70 mm lens on a 35 mm camera. The terms crop factor and focal length multiplier were coined to help 35 mm film format SLR photographers understand how their existing ranges of lenses would perform on newly introduced DSLR cameras which had sensors smaller than the 35 mm film format, but often ...

  9. Full-frame DSLR - Wikipedia

    en.wikipedia.org/wiki/Full-frame_DSLR

    The edges are cropped off, which is equivalent to zooming in on the center section of the imaging area. The ratio of the size of the full-frame 35 mm format to the size of the smaller format is known as the "crop factor" or "focal-length multiplier", and is typically in the range 1.3–2.0 for non-full-frame digital SLRs.
