The size of the cameras imaging device (CCD) also affects the angle of view, with smaller devices creating narrower angles of view when used on the same lens. However, the format of the lens is irrelevant to the angle of view. It merely needs to project an image which will cover the device, i.e. the same format of the camera or larger. This also means that 1/3" cameras can utilize the entire range of lenses from 1/3" to 1" with a 1/3" 8mm lens giving the same angle as a 2/3" 8mm lens. The latter combination also provides increased resolution and picture quality as only the center of the lens is being utilized where the optics can be ground more accurately. |
