The “-S” stands for “short back focus” and means that the lens design protrudes more deeply into the camera body. The “EF” in “EF-S” is the standard Canon EOS “Electro-Focus” mount, introduced in 1987. The non-L Canon zoom lenses are optimized for light weight and low cost and won’t be especially high in optical quality.ĮF-S lenses are designed for Canon’s small-sensor digital cameras, such as the Digital Rebel. Note that there are some non-L prime (fixed focal length or non-zoom) lenses, such as the 50/1.4, that offer extremely high optical quality. An L lens might be very heavy and expensive. An L lens will always be mechanically tough and well-sealed against water and dust. An L lens will always have good optical performance, even if it is a wide-range zoom that is challenging to design.

The L lenses are Canon’s expensive lenses designed for professional photographers. When using a USM lens, the photographer can push the shutter release (or a button on the rear of the camera, if a custom function is set) and let the autofocus system do its best, then touch up the focus manually by twisting the lens ring. The cheaper Canon lenses have a motor that must be clutched out with a switch if the photographer wishes to focus manually. There is no motor in the body as is the case with Nikon, for example. All Canon EOS-system lenses have built-in focus motors.

The alternative to an IS lens would be mounting the camera on a tripod or using a high ISO setting, which reduces image quality but allows the use of higher shutter speeds. An IS lens will allow you to use slower shutter speeds without introducing camera shake. IS is especially important at long focal lengths, e.g., 200mm and above, because the lens magnifies camera shake at the same time it is magnifying the subject. IS is “image stabilization”, a technology lifted from camcorders in which the camera electronically compensates for unsteady hands.

APS-H sensor bodies are good for sports photography and photojournalism delivering fast performance. A 100mm telephoto lens that would be ideal for portraits on a film or full-frame sensor body gives a 150mm equivalent perspective on a small sensor (“ APS-C”) body. Small sensor bodies are good for telephoto work, such as wildlife photography.
