[QUOTE="WhiteLight, post: 89017, member: 9556"] That's the standard measurement & nomenclature for lenses. How else would you like a 50'mm' & a 35'mm' lens be named? [COLOR=#0000ff][I][B]"The focal length of a lens is defined as the distance in mm from the optical center of the lens to the focal point, which is located on the sensor or film if the subject (at infinity) is "in focus". The camera lens projects part of the scene onto the film or sensor. The field of view (FOV) is determined by the angle of view from the lens out to the scene and can be measured horizontally or vertically. Larger sensors or films have wider FOVs and can capture more of the scene. The FOV associated with a focal length is usually based on the 35mm film photography, given the popularity of this format over other formats." [/B][/I][/COLOR] -dp review [/QUOTE]
