The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length.These lenses are based on the classic double-Gauss lens, [1] with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3 [1] and its faster cousins adding additional elements.

There is no precise definition of the term, but lenses marketed as "standard zoom" usually cover a range of at least 30mm to 70mm in terms of 35mm equivalent focal length with an optical zoom ratio of 2.5× (e.g. 28-70mm) to 5× (e.g. 24-120mm) — the most common being 3× (e.g. 24-70mm). [1]

Canon FX with FL 50mm f/1.8. Canon FL refers to a lens mount standard for 35mm single-lens reflex cameras from Canon. It was introduced in April 1964 with the Canon FX camera, replacing the previous Canon R lens mount. The FL mount was in turn replaced in 1971 by the Canon FD lens mount. FL lenses can also be used on FD-mount cameras.
Thanks, but this article is about Canon 50mm prime lenses. There are so many zoom lenses that include 50mm in their range, it would be confusing to include them here. There's already an article dedicated to the Canon EF-S 18-55mm lens, anyway. - Pointillist 07:23, 20 August 2010 (UTC)
