Great images start with great lenses and, in many ways, an SLR is defined by the quality, breadth and scope of its associated system of lenses. For many, Canon EF Lenses alone are reason enough to choose the EOS System. A unique blend of the world’s most advanced optical, micro-electronic and precision manufacturing technologies, EF Lenses are perfected in Canon’s laboratories and proven in the field. Whatever you shoot, whatever your budget, there are Canon Lenses perfect for your needs.

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.

Designed for the Canon EOS 7D, 70D, 60D, and 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. The EF-S 17–85mm f/4–5.6 IS USM is a perfect example of this technology. With a compact design, a 35mm equivalent range of 27–136mm and Optical Image Stabilizer technology, it’s a superlative walk-around lens...possibly the only lens you’ll need to enjoy digital SLR photography.

Designed for the EOS M Digital Camera, EF-M lenses are compact and lightweight, bringing superb EOS optics and optimized performance in small packages. The EF-M 18–55mm f/3.5–5.6 IS STM is an exemplary standard zoom with high image quality, Optical Image Stabilizer and Dynamic IS (for movie shooting mode) with a stepping motor providing extremely quiet and smooth continuous AF for video shooting.

Macro Lenses – Canon’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.

A life-size macro lens – that is, a 1x magnification – records an image on film at its actual size. For example, if it has a diameter of 1 in., it will occupy 1 in. of your actual slide or negative. With a digital SLR, at 1.0x magnification, the image projected onto your camera’s sensor will likewise be the same size at the sensor plane as the actual subject itself. Other macro lenses have lower or higher magnifications. A lens with 0.5x magnification will produce an image on film that is half the size of the actual subject. Your 1 in. subject, then, would only occupy 0.5 in. on film.

In the other direction, a 5x magnification lens will convert the 1-in. subject to a 5-in. diameter image. Since the entire image won’t fit in the frame of your film, you will have an enlarged image of a detail of the subject.

Magnification is not the same as focal length. A 50mm lens and a 180mm lens might both be macro lenses with, for example, 1.0x magnification. The advantage of the longer lens is that it allows greater distance from a subject, while allowing the same magnification in the final image. The 180mm lens is ideal for shooting tiny subjects without disturbing them; the 50mm is a better choice for copying flat documents.

Tilt-Shift Lenses — 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.

Tilt Movements alter the angle of the plane of focus between the lens and focal plane, and Shift Movements move the lens’ optical axis in parallel.

Tilt Movements — Using a normal lens, shallow or deep focus is controlled by the size of the aperture used to adjust depth-of-field. Canon TS-E Lenses can achieve this by the tilting of the lens barrel in relationship to the focal and subject planes. This allows for extremely deep focus even at wide open apertures, and shallow focus at smaller apertures.

Shift Movements — By keeping the camera level, and using the shift function to raise the lens instead, this perspective effect can be corrected. With the camera’s focal plane set parallel to the building, shifting the lens upward will obtain a more rectangular-looking building.

Fisheye and Fisheye Zoom Lenses — Perfect for super wide-angle and special effect photography, the Canon EF 8–15mm f/4L Fisheye USM is the world’s first fisheye zoom lens that delivers circular images with a 180° angle of view on full frame DSLR cameras, and zooms to a 180° diagonal angle of view on APS-C SLR cameras like the EOS 7D.

Softfocus — The EF 135mm f/2.8 with Softfocus lens gives you the choice of razor-sharp images, or two degrees of soft focus with the twist of a ring. The Softfocus effect delivers a natural, beautiful softening effect that envelops the subject in a soft light, throughout the whole image. It smoothes skin tone in portrait photography, and softens landscape and flowers to make dreamy images. Even for Softfocus shots, focusing with AF is quick and accurate.

In the 35mm format, a focal length of 50mm is closest to what the eye sees. This focal length is used as a reference point for lens categories. For example, lenses with a shorter focal length are called wide-angle lenses, while those with a longer focal length are called telephoto lenses. Single focal length lenses have only one focal length, while zoom lenses have a range of focal lengths.

Angle of View indicates how much coverage of a scene you can see through the lens. Telephoto lenses have a narrower angle of view than wide-angle lenses.

Perspective refers to the size relationship between the near and far objects that you can see at the same time. When distance is short and the angle of view is wide (with a shorter focal length), the perspective becomes more apparent. And at greater distances with a narrow angle of view (with a longer focal length), the perspective becomes less apparent. The image also becomes more compressed, with the far objects looking like they are right behind the near objects.
