Canon EF 28-300mm f/3.5-5.6L IS USM Zoom Lens

Canon's EF 28-300mm f/3.5-5.6L IS USM is an entirely new L-series design lens (and a significantly enhanced successor to Canon's EF35-350mm f/3.5-5.6L USM zoom introduced 11 years ago). Though it offers 11x zoom capabilities (compared with the 10x capability of its predecessor), this newly designed, 22-element L-series lens combines Canon's newest optical glass advances, faster autofocus and a groundbreaking Image Stabilization system that makes capturing incredible images a snap, even when the zoom is at max, the shutter speed is slow and the camera is handheld.

The EF 28-300mm f/3.5-5.6L IS USM lens features three ultra low dispersion (UD) glass elements that reduce chromatic aberration, and three Aspherical elements that reduce linear distortion and correct spherical aberration during zooming (keeping image resolution and contrast high), together with superior lens coatings that minimize reflection, especially when used with digital SLRs. The shorter minimum focal length of the new lens versus the previous 35-350mm model also makes the EF 28-300mm L zoom more suitable for digital SLRs with image sensors smaller than 35mm format.

Additionally, the EF 28-300mm f/3.5-5.6L IS USM lens features a new, faster autofocus drive thanks to a new AF CPU and revised in-lens software (that accelerates the transmission of data between lens and camera), a powerful, quick and silent ring-type Ultrasonic Motor and an inner focus system that moves only the lens' lighter elements during AF while keeping the front elements stationary.

Because of its extended zoom range, the new EF 28-300mm f/3.5-5.6L IS USM lens features push-pull zooming operation (unlike most other EF lenses that utilize a ring-type zoom) though it does have a zoom adjustment ring that allows a user to loosen, tighten or lock the zoom control. The lens also permits closer minimum focus than previously available -- from 2.3 feet at all focal lengths -- and is capable of filling the frame with a subject as small as 3.2 x 4.8 inches at the 300mm zoom setting.

The lens is compatible with optional EF12/EF12II Extension Tubes at all focal lengths and EF25/EF25II at mid-range and telephoto zoom settings. The EF25 provides a maximum magnification of 0.5x, effectively filling the frame with a subject approximately 2 x 3 inches at the 300mm zoom setting. It is also compatible with the 77mm 500D and 500 Close-up lenses for a maximum magnification of 0.58x.

The EF 28-300mm f/3.5-5.6L IS USM lens kit includes a newly designed bayonet mount lens hood, a detachable tripod collar and a soft lens case.

Key Features of the Canon EF 28-300mm f/3.5-5.6L IS USM Zoom Lens

Image Stabilization Technology With Shake-Detecting Gyro Sensors

Canon has developed a series of truly unique lenses equipped with an Image Stabilizer (IS) function that let you capture photos that would otherwise be blurred due to camera movement, greatly expanding the range of handheld-camera photography. In many shooting situations where photographers are not allowed to use a tripod or flash, such as art museums and concert halls, Canon IS lenses are your ticket to sharper pictures.

Blurred pictures due to camera shake become more of a problem when taking pictures in dim light - at dusk, indoors, on a cloudy day. And the chance of getting blurred pictures is greater when using longer focal length lenses that magnify the image and any associated movement. To overcome these problems, Canon developed the world's first SLR lens with a built-in image stabilizer. Electronic signals emitted by vibration-detecting gyro sensors are used to move the image-stabilizing lens group in parallel along the optical axis, providing clear picture quality at all times. Actual shooting tests result in improvement equivalent to using a shutter speed two steps faster.

Among the EF 28-300mm f/3.5-5.6L IS USM lens' most significant enhancements is its highly refined Image Stabilization (IS) system with new shake-detecting gyro sensors. IS is now effective for correction of up to three shutter speed steps for handheld photography, 50% better than the original EF 75-300mm IS lens. Additionally, IS remains effective with the EF 28-300mm L lens even when it used on a tripod, improving image quality by helping to eliminate the effects of reflex mirror vibration at slow shutter speeds that are typically required in low light. The lens features an IS mode switch that allows the user to select Mode 1 for general stabilization or Mode 2 for deliberate panning. IS is activated within 0.5 seconds of depressing the shutter halfway.

Ultrasonic Motor

Powered by Canon's exclusive Ultrasonic (USM) motor for autofocusing, the EF 28-300mm f/3.5-5.6L IS USM is silent in operation and very quick to focus. There is virtually no whining noise as the lens focuses to distract the subject or draw attention to the photographer. Most important for the photographer in the field, the motor draws minimal power so the camera batteries last longer.

Ultra-Low Dispersion UD Glass

The EF 28-300mm f/3.5-5.6L IS USM is constructed using the finest optics including three UD (Ultra-Low Dispersion) glass elements designed to correct chromatic aberrations, resulting in extremely sharp images with excellent color rendition.

Two Aspherical Lens Elements

Wide-angle lenses and fast normal focal-length lenses often suffer from an optical problem -- spherical aberration -- which causes an overall softening and optical "smearing" of the image. Canon has developed four different manufacturing technologies to produce Aspherical lens elements, which combat this problem. Aspherical optics, which have an extremely precise variable curvature of one or both sides of a lens element, also allow more compact lens designs and permit lighter lenses with fewer elements.

Inner Focusing and Rear Focusing

An inner focusing lens has the focusing lens group(s) in front of the diaphragm, while a rear focusing lens has the focusing lens group(s) behind the diaphragm. Both focusing systems allow the focusing lens group to be small. This minimizes the load on the actuator which drives the autofocus. In turn, the AF speed is faster. The whole optical system can also be made more compact. Also, since the lens does not rotate during focusing, the effects of a circular polarizing filter or gelatin filter remain intact.

Full-Time Manual Focus

Ring-type Ultrasonic Motor allows manual focusing without switching out of the auto mode, making this lens ideal for many photographic applications including sports, photojournalism, portraits, and landscapes.

EF Lens Mount

In designing the EF lens mount, Canon engineers gave photographers a lot more than simply a way to quickly attach an interchangeable lens to a camera body. With the elimination of mechanical connections and the incorporation of an electronic interface between the camera and lens, Canon cameras have greater flexibility with regard to incorporating future technologies and future system upgrades. This fact has already been proven with a vast increase in AF speed, increased functionality such as predictive autofocus systems found in EOS cameras, auto-aperture tilt-shift (TS-E) lenses, the use of ultrasonic motors and the development of the Image Stabilizer lens.

The fully electronic mount system has none of the shock, operational noise, abrasion, play, lubrication requirements, slow response, diminished precision caused by lever operation, or design restrictions related to linkage mechanisms used to transfer data. Furthermore, operation and reliability are significantly improved. And, a lens operation self-test system, using the lens' built-in microcomputer, can even warn of malfunctions through the camera's LCD readout to help ensure high reliability.
