In digital photography, the image sensor format is the shape and size of the image sensor. ... Sensor size is often expressed as optical format in inches. Other ...
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).
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.
It's not the brand name or the quality of the lens, the touch screen technology or the LCD screen size, and not the array of functions it offers or shooting presets available – it's the size of ...
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...

The image sensor format, between those of larger SLRs using "full-frame" and APS-C sensors, and smaller point-and-shoot compact digital cameras, yields intermediate levels of cost, performance, and convenience. The size of the sensor is smaller than most DSLRs and this implies that lenses, especially telephoto lenses, can be smaller.
Of course, the actual focal length of a photographic lens is fixed by its optical construction, and does not change with the format of the sensor that is put behind it. Most DSLRs on the market have nominally APS-C-sized image sensors, smaller than the standard 36 × 24 mm (35 mm) film frame. The result is that the image sensor captures image ...
