Overview

This is the longest telephoto lens among Canon’s lineup, and a terrific choice for any long-distance application-outdoor sports, wildlife, news photojournalism, and so on. It’s actually lighter than Canon’s EF 600mm f/4L IS lens, weighing just under 10 lbs. It uses a refined optical design, with two fluorite lens elements, one UD element, and one Super-UD-glass element, for outstanding correction of color fringing and superb contrast and sharpness. This super-telephoto lens uses magnesium-alloy barrel construction to enhance its light weight, and has weather-resistant gaskets throughout for use in harsh conditions. It’s compatible with both the EF 1.4x II and 2x II tele extenders for even more reach: EOS cameras with 45 AF points will continue to provide autofocus at the center AF point when the lens is used with the 1.4x extender. Finally, it’s image stabilized, providing up to 4 stops of correction for camera shake. This makes it even more practical in many situations.

L-series quality

The L-series is Canon’s flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are highly resistant to dust and moisture.

 

 

Four-Stop Image Stabilizer

Image Stabilizer (IS) technology allows the use of shutter speeds up to four times slower than normal, with no perceptible increase in image blur. Automatic panning detection turns off IS in either the horizontal or vertical direction when following moving subjects.

Aspherical, Fluorite, UD and Super-UD elements

For optimum visual performance, the lens incorporates four types of special optical elements: aspherical elements to correct spherical aberrations, and Fluorite, UD (ultra-low dispersion) and Super UD elements to eliminate secondary chromatic aberrations. The result is crisp, high-contrast and undistorted image quality, all the way to the edge of the frame.

Magnesium alloy build

At just 4.5kg, the EF 800mm f/5.6L IS USM is a relatively lightweight super-telephoto lens, suitable for limited hand-held shooting. Its magnesium alloy build keeps its weight comparable to shorter telephoto lenses.

Ultrasonic focusing

A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Super Spectra coating

Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera’s sensor.

Smooth background blur

A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background.

 

 

 

Features

Fluorite Lens Elements

Substantially corrects chromatic aberrations in the telephoto range

Fluorite is a type of mineral that is the crystallised form of calcium fluoride. It possesses optical properties such as a low refractive index and a low dispersion. Natural fluorites are small in size, and cannot be used in DSLR camera lenses. In 1969, Canon established a technology for creating artificial crystal fluorite and developed a special technology with a polishing process that takes four times longer than usual, the first in the world to succeed in commercialising the use of fluorite in photographic lenses. By utilising the low-dispersion characteristics of fluorite, the occurrence of secondary spectrum, which is unavoidable in conventional optical glass, can be eliminated almost entirely. Image quality is significantly enhanced as a result, enabling vivid, sharp, and yet detailed image expression.

Super UD Lens Elements, UD Lens Elements

Effect similar to fluorite lens elements

The chromatic aberration correction effect is remarkable when a fluorite element is used. However, due to the high cost of fluorite compared to other materials, it cannot be employed widely on many lenses. To resolve this issue, Canon developed the UD (Ultra Low Dispersion) lens element, which is characterised by a low refractive index and low dispersive properties. It is widely employed in many lenses due to its ability to enhance the elimination of secondary spectrum.

IS (Image Stabilizer)

In-lens correction of camera shake

Canon was the first in the world to develop the IS (Image Stabilizer), an in-lens system to correct camera shake in DSLR cameras. Compared to the in-camera Image Stabilizer feature, not only is the IS capable of stabilising the viewfinder image, it also helps to improve AF accuracy.
The underlying principle is that the amount of misalignment between the image of the subject and the optical axis of the lens is detected by two vibration-detecting gyro sensors. The corrective optical system inside the lens is then moved accordingly in the vertical or horizontal direction to stabilise the image of the subject on the imaging plane.
Most blurry pictures occur as the result of camera shake, which inevitably happens when you take handheld shots. Such blurring is more obvious at slow shutter speeds, which usually occur at low light settings such as during indoor portrait or night street photography because the low amount of light requires the sensor to be exposed for longer. For that reason, photographers usually make up for that by setting a higher ISO speed or using a tripod and remote shutter release. Both have their merits, but also some demerits.

For instance, while increasing the ISO speed also increases the shutter speed, noise occurs at high ISO speeds. There is therefore a limit to how high you can set the latter without compromising on image quality. Similarly, while using a tripod and remote shutter release keeps camera shake to a minimum, they are practical only for certain shooting scenes as prior setup is required.

IS, on the other hand, is able to suppress camera shake to a certain degree even for such scenes, increasing the range of scenes for which you can take handheld shots. Depending on the lens, the image stabilization effect may allow you to shoot at 2-5 shutter speed stops slower than without IS.

Ring USM, Micro USM, Nano USM

Enables silent and high-speed focusing

USM (Ultrasonic Motor) was first put into practical application in the world by Canon. USM drives the lens by transforming ultrasonic vibrations into rotation energy. Not only does it consume little power, it has high efficiency, torque and response, enabling high-speed focusing with almost no operating sound emitted.

There are three types of USM . The round-shaped Ring USM is simple in structure, and is best suited for use in a circular lens tube. It is especially useful for driving lenses such as large-diameter or super telephoto ones due to its high torque, and it also allows for full-time manual focusing. Meanwhile, the Micro USM can be employed on many types of lenses because it is low in cost and not subject to restrictions on the lens diameter. In 2002, Canon contributed further to the downsizing of lenses with the development of the Micro USM II, which is about half the size and weight of the Micro USM . And in 2016, Canon introduced Nano USM, which not only realizes a high speed AF that rivals that achieved by Ring USM, but also is able to operate quietly and seamlessly. It’s not an exaggeration to describe Nano USM as the most ideal motor for normal-use lenses that are meant to handle both still photography and movie shooting.

Nano USM—The thin and tiny USM motor that achieves fast and smooth AF

Thin and compact, this USM, the latest to be developed by Canon, made its debut in 2016 on the EF-S18-135mm f/3.5-5.6mm IS USM. Computer chip-shaped (a factor that allows a more compact lens design) with power sources in the form of transducers, it connects directly to the AF actuating mechanism. It possesses a speediness and responsiveness that rivals that of the Ring USM, combined with a control that equals that of STM (lead screw-type). Its main benefit lies in enabling quiet, smooth AF operation in compactly-sized lenses such as standard zoom lenses. Also very suitable for movie-shooting, its high speed AF is able to handle scenes with subjects that are moving at a fast speed as well as those with unpredictable movements.

The Nano USM is shaped like a computer chip, and has 2 transducers in its center.

Moving along the top of the slider, the Nano USM directly drives the main AF power source. As this motor not only allows for fast and smooth AF but is also small in size, it makes it possible for the lens that utilize it to be around the same size as lenses with STM.

 

Inner Focusing, Rear Focusing

Enables high-speed and precise AF

The inner focusing and rear focusing systems adjust the focus by moving only some of the lens elements inside the lens. Inner focusing refers to the type where the focusing lens group is located in front of the aperture diaphragm, while this group is positioned behind the aperture diaphragm in the case of the rear focusing type. As a smaller number of lens elements need to be moved, AF speed can be increased, and the size and weight of the entire lens can also be reduced. Besides, the front of the lens does not extend out during focusing, thus making it easy to achieve an integral lens structure, which in turn contributes to the enhanced robustness of the design. Yet another advantage of this system is that it enhances the operability of polarising filters as the filter mount does not rotate during focusing.

Full-time Manual Focusing

Enables MF immediately after AF

Many of Canon’s EF lenses are equipped with “full-time manual focusing”, which allows manual focus right after auto focus is complete, just by turning the focusing ring and without the need to switch to MF mode. All Ring USM and STM lenses support full-time manual focusing.

Dust- and Drip-Resistant, Fluorine Coating

Dust- and drip-proof for shooting under harsh conditions

Many of Canon’s L lenses come with a dust- and drip-proof structure, with rubber sealing applied to the interface area between the joint of the mount and the camera, as well as sealing at the movable parts such as the focusing ring and the lens extension tube. Rubber materials are also employed even at the smallest parts, such as the switch panel and the insertion slot of the drop-in filter compartments. The excellent dust- and drip-resistance enhances the usability of lenses under adverse weather, and helps to address the needs of professional photographers who are required to perform shoots under harsh shooting conditions. Fluorine-coated lenses allow dirt attached to the lens to be wiped off easily.

Circular Aperture Diaphragm

Expresses point light sources in beautiful round bokeh

The aperture is made up of several blades, the number of which determines the shape of the bokeh effect, such as in the case of illumination, light seeping through the leaves of a tree, and light reflection from the water surface. Light normally appears round when seen through our eyes, thus expressing light in a circular shape adds a more natural and soft touch to the resulting image. Almost all EF lenses employ a circular aperture diaphragm.
