English: Log-log graphs of focal length vs crop factor vs diagonal, horizontal and vertical angles of view for film or sensors of 3:2 and 4:3 aspect ratios. The yellow line shows an example where 18 mm on 3:2 APS-C is equivalent to 27 mm and yields a vertical angle of 48 degrees. Simulated bitmaps were derived from File:1_times_square_night ...
In other words, the angle of coverage is determined by the lens and the image plane while the angle of view (AOV) is decided by not only them but also the film or image sensor size. The image circle (giving the angle of coverage) produced by a lens on a given image plane is typically large enough to completely cover a film or sensor at the ...
Diagram of the APS-H, APS-C, and APS-P film frame sizes, in comparison to the standard 35 mm frame File usage The following pages on the English Wikipedia use this file (pages on other projects are not listed):
Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film or sensor plane to construct a lens.
Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.
