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.
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).

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 ...
The sizes of sensors used in most current digital cameras, relative to a 35 mm format. A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format (36 mm × 24 mm). [1] [2] Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format.

List includes metropolitan areas according only to the studies of ESPON, Eurostat, and OECD.For this reason some metropolitan areas, like the Italian Genoa Metropolitan Area (with a population of 1,510,781 as of 2010 [1]) or the Ukrainian Kryvyi Rih metropolitan area (with a population of 1,170,953 as of 2019 [2]), are not included in this list, with data by other statistic survey institutes.
Various sensor aspect ratios may be used which all fit inside the same image circle, 3:2, 4:3, 16:9, etc. A lens to be used on a camera that provides movements must have an image circle larger than the size of the image format (Adams 1980, 54).
