The EF 100 mm F/2.8 Macro USM is a medium telephoto lens with a macro feature providing a 1.0x magnification. With eight aperture blades, creative background blur is possible to help make the subject stand out. The lens features a focusing limiter switch which limits the focus range to improve AF speed. ...

Includes:: dust & moisture resistant seals to protect against harsh weather conditions. A fast f/2.8 aperture delivers impressive low light performance & depth-of-field control. The aperture is fixed over the full focal range, allowing photographers to maintain a constant fast shutter speed when zooming. A ring USM (Ultrasonic Motor) drives extremely rapid auto focus with near-silent operation. Full time mechanical manual focus override is available without having to switch out of AF. The lens offers a minimum focusing distance of 0.28m throughout the zoom range. The EF 16-35mm f/2.8L II USM incorporates three aspherical elements to ensure corner-to-corner sharpness & clarity throughout the focal range. Two UD (Ultra Low Dispersion) elements virtually eliminate chromatic aberrations. Super Spectra lens coatings suppress flare & ghosting
- more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help maintain accurate color balance & high contrast. The lens passes distance information back to the camera's E-TTL II flash system for consistently accurate flash metering. The EF 16-35mm f/2.8L II USM lens comes supplied with a lens hood & soft case.

The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional & high amateur SLR EOS camera users. While it is an excellent lens when used with an analog SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view Approx. equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens. The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent color balance & minimizes ghosting & flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity. Minimum focusing distance is just 28mm throughout the entire zoom range. The Auto-focus works silently & quickly thanks to a fast central processing unit with an enhanced AF algorithm. You can override AF mode with manual focus should you wish. Controlled by an electromagnetic diaphragm, the EF17-40mm f/4L USMs circular aperture can achieve a more attractive appearance to out of focus background areas in a picture. The front of the lens does not rotate as you focus. This means, for example, that polarizing filters still function effectively as you zoom in & out. At the rear of the lens theres a drop-in gelatin filter holder. Highly resistant to moisture & dust, the EF17-40mm f/4L USM is ideally suited for use in harsh environments. Environment friendly lead-free glass is used throughout its construction. ...
