![]() ![]() The Canon EOS 50D will work with pretty much any EF-mount lens ever made, as well as with the special EF-S lenses designed for cameras with APS-C size sensors. Designed with a smaller image circle (the area covered by the image on the film/sensor plane), EF-S lenses tend to be smaller and lighter than full-frame models with the same focal length and maximum aperture. EF-S lenses can't be used on full-frame Canon cameras, nor on their models with 1.3x crop factors, like the current EOS-1D Mark III, but small-sensor cameras like the 50D can use any full-frame lenses in Canon's arsenal. ![]() ![]() The sub-frame sensor on the Canon 50D means that it has a smaller angle of view (by a factor of 1/1.6x) than a full-frame camera with any given lens. While most properly called a "crop factor", the 1.6x ratio is most commonly referred to as the "focal length multiplier" since that's how it works in practice: Any lens used on the Canon 50D will have the same field of view as one with a 1.6x greater focal length will when attached to a 35mm camera. 1 1: Functions and services may not be available in certain printers, countries or regions and enviroment. For example, a 100mm lens on the Canon 50D will show the same field of view as a 160mm lens on a camera with a 35mm frame size.
