Canon U.S.A. Introduces Three New EF and EF-S Lenses, the EF 100mm f/2.8L Macro IS USM, EF-S 15-85mm f/3.5-5.6 IS USM, and EF-S 18-135mm f/3.5-5.6 IS

Canon U.S.A., Inc., a leader in digital imaging, continues its advancement of EOS lens technology with the introduction of three new EF and EF-S lenses – EF 100mm f/2.8L Macro IS USM, EF-S 15-85mm f/3.5-5.6 IS USM and the EF-S 18-135mm f/3.5-5.6 IS, lenses. The new EF 100mm f/2.8L Macro IS lens is the world's first camera lens featuring Canon's new Hybrid Image Stabilization (Hybrid IS) technology*, compensating for both angle camera shake and shift camera shake, up to four shutter speed steps. The EF 100mm f/2.8L Macro IS USM lens is compatible with all EOS cameras, while the EF-S 15-85mm and EF-S 18-135mm zoom lenses are designed specifically for Canon digital cameras that are compatible with EF-S lenses.**

EF 100mm f/2.8L Macro IS USM lens
The EF 100mm f/2.8L Macro IS USM lens could very well be the essential multipurpose lens for every camera bag due to its ability to capture sharp close-up images of small objects as well as beautiful portrait-length telephoto shots. The incorporation of Canon's new Hybrid IS in this L-series macro lens allows it to compensate more effectively for camera shake during close-up shooting and marks a significant improvement for professionals and advanced amateurs utilizing macro photography for portrait, nature or wedding shoots.

New Hybrid IS Technology: Designed Especially for Macro Photography
The world's first* optical image stabilizer for SLR cameras was introduced in the EF 75-300mm f/4-5.6 IS USM in 1995. Since then, Canon has made continual advancements in IS systems to enhance panning capability and improve compensation for camera shake. Now, in a move aimed at extending image stabilization to the macro realm, Canon introduces its Hybrid IS in the new EF 100mm f/2.8L Macro IS USM – another first for Canon and the world.

Conventional image stabilization technology is useful for reducing the effects of camera shake in non-macro shooting situations. When shooting handheld close-ups at 1x, however, camera shake makes it difficult to achieve acceptable results even with lenses incorporating conventional image stabilizers. Now, thanks to the Hybrid IS found in the EF 100mm f/2.8L Macro IS USM, Canon extends IS technology to the macro realm, making it easy to obtain clear handheld close-ups – a world first* and a definite advantage in environments where use of a tripod is not an option.

In order to combat the effects of camera shake in a macro lens, the IS system must be able to compensate for both angular camera shake and shift camera shake – problems that become more apparent as magnification increases. The effects of shift camera shake are rarely noticeable when shooting outside the macro realm, such as in landscape photography. But when shooting extreme close-ups, even the slightest amount of camera shake, either of the angular or shift variety, can adversely affect image quality.

In macro photography, shift camera shake and angular camera shake affect both the image formed on the sensor and the image shown in the viewfinder. This is especially relevant to handheld shooting at 1x, since the inability to properly compose and focus due to a shaky image in the viewfinder makes it extremely difficult to record sharp images.

Conventional image stabilizers of the type found in Canon IS lenses incorporate an angular velocity sensor (vibration gyro) to compensate for angular camera shake. Based on the amount of camera shake detected by the sensor, the IS system calculates the amount of blur on the image plane, after which lens elements in the IS are positioned to compensate for the shake. However, this type of image stabilizer can neither detect nor correct shift camera shake common to handheld macro photography.

The Hybrid IS includes an acceleration sensor in addition to the conventional angular velocity sensor (vibration gyro). Based on the amount of camera shake detected by the two sensors, a newly developed algorithm calculates the amount of blur on the image plane, after which lens elements in the IS are positioned to compensate for the two types of shake – a first in an interchangeable lens for SLR cameras and an excellent way to solve the problem of camera shake in macro photography.



EF-S 15-85mm f/3.5-5.6 IS USM lens
The versatile focal length, extreme wide angle and stunning image quality of Canon's new EF-S 15-85mm f/3.5-5.6 IS USM lens makes this the ideal multipurpose wide-angle zoom lens for the photographer shooting a wedding or exotic vacation. Featuring three aspherical elements and one UD glass element for outstanding image quality, the zoom range of this lens is equivalent to 24-136mm on a full-frame camera. When coupled with Canon's new EOS 7D DSLR, this lens provides moviemakers and videographers with a phenomenal focal range for wide-angle scenic footage and zoomed in telephoto shots.




EF-S 18-135mm f/3.5-5.6 IS lens
Canon's new EF-S 18-135mm f/3.5-5.6 IS lens is the perfect Image Stabilized lens for advanced photographers looking for a wide-angle zoom lens with telephoto capabilities. Featuring a compact IS unit with shake correction up to four shutter speed steps, the zoom range of this lens is equivalent to 29-216mm on a full-frame camera.

CANON U.S.A. Introduces EF200mm f/2L IS USM and EF800mm f/5.6L IS USM Lenses

Canon U.S.A., Inc., a leader in digital imaging, today announced the launch of two new telephoto lenses for use with its EOS SLR cameras: the EF200mm f/2L IS USM*/** and the EF800mm f/5.6L IS USM*/**, the world's longest focal length lens with an Optical Image Stabilizer system.*** The Company, which exhibited prototypes of the lenses during PhotoPlus Expo in New York last October, is launching them at the PMA tradeshow (booth E101) at the Las Vegas Convention Center, January 31 to February 2.


"The development of these two new lenses continues to show how Canon actively responds to the imaging needs of our professional and advanced amateur customers. We are proud to provide the right equipment to help photographers capture the best and brightest images under all conditions," said Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A.

The EF800mm f/5.6L IS USM and EF200mm f/2L IS USM are professional L-Series lenses that incorporate the latest generation of Canon's high-performance Optical Image Stabilizer system (OIS), giving them a stabilization effect equivalent to a shutter speed four settings faster. In addition, they feature optical systems utilizing fluorite and UD lens elements to provide excellent chromatic aberration correction for high-resolution, high-contrast shooting performance. Both lenses use only lead-free glass, and also incorporate lightweight yet durable magnesium alloy lens barrels with enhanced resistance to moisture and dust.
EF800mm f/5.6L IS USM

The Canon EF200mm f/2L IS USM is an exceptionally sharp lens that is significantly lighter (2520g/5.5 lbs. vs. 3000g/6.6 lbs.) than its predecessor, the renowned EF200mm f/1.8L USM lens, while adding OIS and a weather-resistant design. Ideal for all kinds of low-light photography including portraiture as well as indoor sports, the EF200mm f/2L IS USM has a close-focus setting of 1.9 m/6.2 feet and a circular aperture system that enhances its background blur rendition at wide apertures.

EF200mm f/2L IS USM
The Canon EF800mm f/5.6L IS USM is not only the longest focal length lens available with OIS, it is also virtually the same physical size as the EF600mm f/4L IS USM (461mm vs. 456mm), while weighing nearly 2 lbs. less (4500g/9.9 lbs. vs. 5360g/11.8 lbs.). These outstanding features were made possible by the use of a lightweight magnesium alloy lens barrel construction and a state-of-the-art super-telephoto optical system featuring 2 fluorite elements as well as Super UD and UD glass elements. The EF800mm f/5.6L IS USM is well-suited for a wide variety of long-range photo applications such as wildlife and nature photography as well as sports and documentary photojournalism.

Canon expands EF-S range with two new lenses (EF-S 18-55mm f/3.5-5.6 IS and EF-S 55-250mm f/4-5.6 IS)

Canon today strengthens its EF-S series of lenses with the launch of the EF-S 18-55mm f/3.5-5.6 IS and EF-S 55-250mm f/4-5.6 IS. With equivalent focal lengths of 29-88mm and 88-400mm respectively, the lenses are the first in the EF-S series to incorporate a 4-stop Image Stabilizer, dramatically extending low-light performance. Both lenses incorporate specialist optics to achieve exceptional image clarity - the EF-S 18-55mm f/3.5-5.6 IS employing an aspherical lens element with the EF-S 55-250mm f/4-5.6 IS benefiting from an Ultra-Low Dispersion (UD) lens element.

The lenses are built to fit exclusively on those EOS cameras with an EF–S lens mount – including the new EOS 40D, EOS 30D, EOS 400D and earlier models.

EF-S 18-55mm f/3.5-5.6 IS




The EF-S 18-55mm f/3.5-5.6 IS is a lightweight general-purpose zoom lens that is ideal for handheld photography in a wide range of lighting conditions. Offering high optical quality, the lens has an 11 element, 9 group construction, including one aspherical element for crisp corner-to-corner detail. The lens maintains a closest focusing distance of just 25cm throughout the zoom range, giving photographs the flexibility to frame up close when needed.

EF-S 55-250mm f/4-5.6 IS



Compact and lightweight, the EF-S 55-250mm f/4-5.6 IS offers the longest zoom range in the EF-S series to date. The 88-400mm equivalent focal length opens up new framing possibilities for owners of EF-S mount cameras shooting wildlife, sports and travel photography. Optical quality is assured through a UD element, which minimises chromatic aberrations that could otherwise cause reduced contrast and colour fringing.

4-stop Image Stabilizer



Canon’s latest optical Image Stabilizer (IS) technology provides up to 4-stop compensation for image blur caused by camera shake and slow shutter speeds. Photographers normally shooting handheld at 1/250 sec can switch on IS to obtain a similarly steady and blur-free result with a shutter speed of just 1/15 second. The inclusion of automatic panning detection makes it easier for photographers to track wildlife and other moving subjects. To ensure consistently accurate results at all zoom positions, the IS system within each lens has been optimised for that lens’ specific focal length range. Since the IS system is based within the lens, the results are visible through the viewfinder when framing the image.


Appealing background blur

Both lenses also incorporate a circular aperture. This helps create an even background blur when depth of field is minimised, giving photographers more creative options for portraiture and similar types of photography.

Super Spectra coatings

Both models employ Canon’s patented Super Spectra coatings to suppress flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.

E-TTL II flash integration

The lenses transmit distance information to the E-TTL II flash system of all current model digital EOS cameras, improving flash exposure metering when used in conjunction with Canon’s range of EX Speedlite flash units.

In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.

  • Lens hood and pouch included in the box


L-series construction
The L-series is Canon’s flagship professional lens range, designed and built to meet the needs of the most demanding professional photographers. The optics of the EF 14mm f/2.8L II USM and other L-series lenses represent the pinnacle of optical performance, enabling focal length/speed/quality combinations not readily attainable using traditional optical technologies.

New perspectives
The lens’ ultra-wide 114° angle of view can be used by photographers to dramatic effect. Effective for photographing buildings and other large subjects where the photographer cannot get enough distance to include everything in the frame, the EF 14mm f/2.8L II USM is also ideal for small interiors. The lens’ closest focusing distance of just 20cm allows photographers to get remarkably close to subjects for creative wide-angle shots.

Aspherical and UD elements
The EF 14mm f/2.8L II USM incorporates two aspherical lens elements to ensure high corner-to-corner sharpness throughout the focus range and at wide apertures. Pristine image quality is further assured through the incorporation of an Ultra-low Dispersion (UD) element, used to suppress chromatic aberration and associated colour fringing.

Super Spectra coatings
In addition to optimised lens shaping to reduce reflections and the use of anti-reflective material inside the lens barrel, the EF 14mm f/2.8L II USM employs Canon’s patented Super Spectra lens element coatings. These suppress flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.
The EF 14mm f/2.8L II USM includes an integrated petal hood and redesigned lens cap.
In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.
