Canon DSLR Camera Lenses
Canon offers one of the world's most comprehensive selection of lenses - including telephoto, macro, fisheye, and tilt/shift - to capture amazing stills and stunning video with incredible clarity and brilliant colors.
Designed for the Canon EOS 7D, 60D, all EOS Rebel and EOS Digital Rebel models with APS-C sized sensors (with a 1.6x crop factor), Canon’s EF-S Lenses take advantage of the sensor’s smaller size, to deliver optimized performance in compact, lightweight designs.
Designed for the Canon EOS 5D Mark II, Mark III, 1D-X, and other full-frame units , Canon EF mount lenses allow photographers to quickly attach a lens to a camera body with a fully electronic mount system has none of the shock, operational noise, abrasion, play, lubrication requirements, slow response, lever operation limitations, or other design restrictions related to mechanical linkage mechanisms. A self-test system, using the lens's built-in microcomputer, can even warn of malfunctions through the camera’s display. The EF mount makes possible high-speed autofocus, precise aperture control and preview, automatic compensation with lens extenders, and forward compatibility with new lens technologies - such as USM and IS - as they are developed by Canon.
Most highly regarded among professional photographers, Canon L-series lenses are distinguished by a bold red ring around the outer barrel. What makes them truly distinctive, however, is their remarkable optical performance — the result of sophisticated Canon technologies, such as Ultra-low Dispersion UD glass, Fluorite and Aspherical elements, and Super Spectra Multi Coating.
Canon’s EF and EF-S Lens lineup has a number of options for true close-up and macro photography. With six macro Lenses for precision, and three screw-on close-up Lenses for convenience, in addition to the Life-Size Converter EF and two Extension Tubes, Canon’s macro Lenses and close-up accessories can uncover detail that is impossible for the unaided human eye to detect.
Tilt-Shift Lenses (TS-E)
TS-E Lenses are capable of tilt and shift movements, which bring many of the advantages of technical view cameras to the EOS System. Tilt movements alter the angle of the plane of focus between the Lens and film plane, making broad depth-of-field possible even at larger apertures; shift movements slide the Lens’s optical axis along the film/sensor plane, enabling photographers to correct or alter perspective at almost any angle.
EF Lenses for EOS M (EF-M)
Designed exclusively for the EOS M Digital Camera, EF-M lenses offer superb image quality for video and photos in a compact size.
Technologies Behind Canon EOS LensesUltra Sonic Motor (USM)
Canon developed the world’s first lens-based Ultrasonic Motor (USM) to power the lens autofocus mechanism. Instead of large noisy drive trains powered by conventional motors, Canon USM lenses employ the minute electronic vibrations created by piezoelectric ceramic elements. The focusing action of the lens is fast and quiet, with virtually instantaneous stops and starts. USM lenses also draw minimal power from the camera, ensuring longer battery life.
Stepping Motor (STM)
A challenge of shooting DSLR video has been achieving continuous autofocus. In response, new Canon EF and EF-S lenses now offer a stepping motor (STM) drive, designed to deliver smooth and quiet continuous AF during video shooting when paired with the Canon EOS Rebel T4i’s Movie Servo AF feature.
Dynamic Image Stabilization (IS)
During video shooting, Canon’s Dynamic IS stabilization offers a greater image stabilization correction range, creating an Image Stabilizer effect equivalent to a shutter speed around 4 settings faster, effective for shooting handheld, while walking, and in similar types of shooting situations.
Diffractive Optics (DO)
Diffractive optics (DO) are special kinds of glass that are used in some lenses. DO lenses, compared to non-DO lenses of similar focal length and aperture values, are usually smaller and lighter and are better at handling chromatic aberration.
Fluoride Ultra-low Dispersion (UD)
Reducing color fringing, or chromatic aberration, has been one of the great challenges in the design of telephoto lenses. L-series telephoto lenses employ Canon’s Ultra-low Dispersion glass to minimize this effect, providing much improved contrast and sharpness.
Aspherical Element (AL)
Wide-angle lenses and fast normal-focal-length lenses often suffer from spherical aberration. Aspherical elements use a varying curved surface to ensure that the entire image plane appears focused, also helping correct curvilinear distortion as one might find in ultra wide-angle lenses. Finally, Canon can design aspherical elements with extremely precise variable curvature of one or both sides, making possible lighter and more compact lenses.
Dust and Water Resistant (DW-R)
Most L-series EF telephoto lenses are highly dust- and water-resistant thanks to rubber seals at the switch panels, exterior seams, drop-in filter compartments and lens mounts. Moving parts, such as the focusing ring and switches, are also designed to keep out environmental contaminants, providing reliable performance under harsh conditions.
Sub Wavelength Coating (SWC)
SWC is a new proprietary lens coating that controls ghost and flare to a far greater degree than with earlier coating technologies. Utilizing SWC technology on large-curvature lens elements that are mainly found in wide-angle lenses will significantly minimize the occurrence of ghosting and flare caused by reflected light in environments that have posed problems.
