Crop Factor

Mainly because the “suitable” focal length relies upon on the sensor dimensions, cameras which are less than complete-frame will involve lenses with shorter focal lengths. For case in point, a digicam with a 1.5x “crop element” will need a lens which is 1.5 times shorter than the regular 50mm, which functions out at 33mm. A number of makers produce 35mm normal lenses to meet up with this requirement.
