The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor. Current digital image sensor size descriptors are the video camera tube equivalency size, not the actual size of the sensor. For example, a 1" sensor has a diagonal measurement of 16 mm. [26] [27]
The optical format is approximately the diagonal length of the sensor multiplied by 3/2. The result is expressed in inches and is usually (but not always) rounded to a convenient fraction. For instance, a 6.4x4.8 mm sensor has a diagonal of 8.0 mm and therefore an optical format of 8.0*3/2 = 12 mm, which is expressed as 1 ⁄ 2 inch in imperial ...
However, the vast majority of C-mount lenses produce an image circle too small to effectively cover the entire sensor which has approximately 22 mm diagonal, this produces vignetting. [1] The Nikon 1 series and the Pentax Q series can use C-mount lenses without vignetting. C mount was created by Bell & Howell for their Filmo 70 cine cameras. [2]
A 50 mm (focal length) lens on an APS-C image sensor format (crop factor 1.6) images a slightly smaller field of view than a 70 mm lens on a 35 mm sensor format camera (full frame sensor). A 80 mm lens (1.6 × 50 mm = 80 mm) with a full frame camera gives the same field of view as this 50 mm lens and APS-C sensor format combination produces.

The latest Leica Leitz and Sharp Aquos R series phones do qualify because, despite using only 94% [b] of their 1.0-type sensors [2] [3] (with 4:3 aspect ratio), they maintain the same crop factor (2.7) and diagonal (1″) as a 1.0-type sensor with 3:2 aspect ratio, since that is the image circle for which their lenses were originally designed.

Both the F200EXR and the S200EXR use the same 12 Megapixel 1/1.6" size sensor while the F70EXR and F80EXR use a 10 Megapixel and 12 Megapixel 1/2" sensor respectively. In 2010, Fujifilm released its final cameras with the Super CCD sensor, the F300EXR and the Z800EXR. Both use the same 1/2" 12 Megapixel SuperCCD EXR sensor with hybrid autofocus ...
