Short title	Camera focal length vs crop factor vs angle of view
Image title	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 by CMG Lee. The yellow line shows an example where 18 mm on 3:2 general APS-C is equivalent to 27 mm and yields a vertical angle of 48 degrees. Simulated bitmaps were derived from http://commons.wikimedia.org/wiki/File:1_times_square_night_2013.jpg .
