EF17-35mm f/2.8L USM

As the newest member of the f/2.8L USM lens line-up, replacing the EF20-35mm f/2.8L, this large-aperture wide-angle zoom lens offers the world's shortest SLR zoom focal length of 17mm. The remarkable 17-35mm zoom range was achieved with the help of 2 aspherical elements, one at the front of the lens and the other at the rear. The front element suppresses distortion while the rear element improves sharpness, especially in the corners of the frame.

The EF17-35mm f/2.8L USM uses a 5-group, 15-element optical formula with inner focusing. At the wide end, edge sharpness is superior to that of the EF20-35mm f/2.8L. Overall optical performance is equal or superior to fixed focal length lenses in its range. It's an ideal lens for photojournalists and scenic photographers who wish to limit the number of lenses they carry.

Employing Canon's exclusive state-of-the-art ring-type Ultrasonic Motor (USM) technology, the EF17-35mm f/2.8L USM provides silent, high-speed autofocus, covering its full range from infinity to 1.4 ft./42cm in less than 0.4 seconds. This is achieved through inner focusing, which reduces the weight of the focusing component while at the same time improving the durability of the lens. Fast and smooth mechanical manual focusing is also available at all times, even when the lens is set for AF.

The non-rotating 77mm filter thread is perfect for circular polarizers and other special effects filters. There is also a drop-in holder on the rear of the lens which accepts up to 3 gelatin filters for increased versatility. A petal-type bayonet-mount lens hood (supplied) provides superb protection against flare and impact. The EF17-35mm f/2.8L USM will be available in April, 1996 at a suggested list price of US$2,550.

EF135mm f/2L USM

With its large maximum aperture, high image quality, fast AF and light weight, the new EF135mm f/2L USM medium telephoto lens is sure to meet the needs of a wide range of advanced amateurs and professional photographers. Taking full advantage of Canon's industry-leading Ultrasonic Motor (USM) technology, the new lens provides silent, high-speed autofocus in a popular focal length. A 10-element optical formula with 2 UD-glass elements serves to correct residual chromatic aberrations, resulting in superb sharpness and high image quality. In addition to its outstanding low-light capabilities, the large f/2 maximum aperture creates a beautiful blur effect in out-of-focus background areas that helps to enhance the image quality of a sharply focused main subject, such as a portrait.

A rear-focusing optical design increases autofocus speed while at the same time reducing lens size and weight, making the EF135mm f/2L USM the lightest lens in its class at 26.3 oz./750g. Canon's USM provides extremely accurate autofocus operation with a drive speed of only 0.75 seconds between infinity and the closest focusing distance of 2.95 ft./0.9m -- the shortest close focus in its class. There's a full-time mechanical manual focus override that works even when the lens is set for AF, and manual focusing itself is remarkably smooth, using a wide rubberized ring.

The non-rotating 72mm filter thread is ideal for a circular polarizer or other special effects filter, and the deep bayonet-mount lens hood (ET-78) provides protection against flare and impact. As an extra bonus, the EF135mm f/2L USM is fully compatible for AF and AE with Extenders EF1.4x and EF2x. The EF135mm f/2L USM will be available in March, 1996 at a suggested list price of US$1,670.00.

EF180mm f/3.5L Macro USM

Now professionals and advanced amateurs can capture life-size images with exceptional clarity even at long range. The EF180mm f/3.5L Macro USM is a telephoto lens that shoots high-quality photos throughout its focusing distance range from life-size 1X to infinity.

Three UD-glass elements are present in a 12 group/14 element optical formula to correct residual chromatic aberrations. Unlike most macro lenses that tend to have more spherical aberration at closer subject distances, this lens employs a double floating element construction which maintains stable imaging performance throughout its focusing range. The large f/3.5 maximum aperture also makes it possible to blur a background for greater effects in close-ups.

Canon's exclusive ring-type Ultrasonic Motor (USM) provides silent and extremely accurate autofocus operation with a drive speed of only 1.3 seconds from infinity to the closest focusing distance of 1.5 ft. Fast and smooth manual focusing is also available during AF mode via the built-in mechanical manual focusing override and wide manual focusing ring.

The EF180mm f/3.5L Macro USM uses inner focusing to keep the lens from expanding or contracting during the focusing process. This feature also helps to protect the focusing components from external shock, thus maintaining precise alignment and increasing durability. The 72mm filter thread never rotates, making it ideal for a circular polarizer or other special effects filter. The lens is also supplied with a detachable tripod collar for superior balance when mounted on a tripod.

The EF180mm f/3.5L Macro USM is compatible for automatic ecposure with Extenders EF1.4x and EF2x for increased magnification up to 2x life-size. Autofocus is supported up to 0.8x life-size when the EF1.4x is used, but manual focusing is required at closer range with this extender, and at all times when using the EF2x. The EF180mm f/3.5L Macro USM will be available in April, 1996 at a suggested list price of US$2,590.00.

EF400mm f/2.8L II USM

As the successor to the EF400mm f/2.8L USM, this super-telephoto lens with its redesigned optical system not only offers the highest performance in its class and a significant reduction in weight, but improved operating ease as well. All this, plus a high level of rugged reliability should make the EF400mm f/2.8L II USM extremely popular with professional photographers for sporting events as well as fashion and photojournalism.

Significant to the improved image quality is the new optical system incorporating a fluorite element in group 2 and UD-glass elements in groups 3 and 5. The combination of these three elements in the 9-group/11-element optical formula serves to substantially reduce residual chromatic aberrations, increasing resolution and improving color fidelity.

Unlike its predecessor which had two protective glass elements, the EF400mm f/2.8L II USM needs only one. The fluorite element, which is more resistant to thermal shock than UD-glass elements, is positioned right behind the protective glass element -- thus eliminating the need for a second protective glass. Also, the overall length of the optical formula has been reduced and the lens barrel wall is thinner. Taken as a whole, these measures have resulted in a weight reduction of 19 oz./540g, making the new lens easier to handle. The lens grip is also wider and positioned forward for a more secure grip during monopod shooting.

Employing Canon's state-of-the-art ring-type Ultrasonic Motor (USM) technology with inner focusing, this lens offers silent, high-speed autofocus with a drive speed of less than 0.7 seconds from infinity to its closest focusing distance of 13.4 ft./4m. The EF400mm f/2.8L II USM provides full-time electronic manual focusing, which results in a number of useful benefits including Canon's exclusive Focus Preset function, which allows the lens to "memorize" a preset distance and come back to it at anytime by turning a "playback" ring next to the focusing ring. A manual focusing speed control allows manual focusing at half, normal or double speed to suit the subject. Autofocusing is operational with either Extender EF1.4x or EF2x attached.

The EF400mm f/2.8L II USM will be available in March, 1996 at a suggested list price of US$12,200.00.
