Angle of View Vs. Field of View. Is There Even a Difference?!

As noted above, a camera's angle level of view depends not only on the lens, but also on the sensor used. Digital sensors are usually smaller than 35 mm film, causing the lens to usually behave as a longer focal length lens would behave, and have a narrower angle of view than with 35 mm film, by a constant factor for each sensor (called the crop factor). In everyday digital cameras, the crop factor can range from around 1 (professional digital SLRs), to 1.6 (mid-marke… WebApr 14, 2024 · Seeing Different Focal Lengths. 35mm is considered the equivalent focal length of a wide-angle lens whereas 50mm is considered a more normal focal length.
