Normal lenses are the ones with focal length roughly equal to diagonal of imaging surface (43mm on 35mm full frame, about 28mm on APS-C). Classic normal lenses are slightly longer (50...58mm on FF, 30...35 on APS-C).

What does normal focal length really mean?
First off, I wanna say that I have a qualification in photo-/videography and of course I do know the principles of normal focal length, how the angle of view relates with the focal length and sensor/film … That gives me a diagonal angle of view of ~35 degrees, as opposed to the ~53 degrees for a normal focal length.
Do I have wierd eyes or a misconception about normal focal length? …
