With a constant f/2.8 aperture throughout the zoom range and a 3-stop Image Stabilizer, the EF-S 17-55mm f/2.8 IS USM provides outstanding performance and framing flexibility in low light conditions.
Features
Change your view. Not your aperture.
High performance wide angle zoom
With an effective focal length range of approximately 27-88mm (35 mm equivalent), the EF-S 17-55mm f/2.8 IS USM is a powerful lens that delivers remarkable image quality. The wide angle zoom allows you to capture more of every scene and adds a new sense of space and perspective to your photography.
Fixed aperture
The large f/2.8 aperture provides excellent results in low light conditions. The aperture remains constant through the full focal length range, allowing you to zoom from approximately 27-88mm (35 mm equivalent) without slowing shutter speed.
Pleasing background blur
A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and isolating your subject from the background.
Image Stabilizer
The EF-S 17-55mm f/2.8 IS USM features Canon’s 3-stop Image Stabilizer (IS). Ideal for handheld work, IS allows the use of shutter speeds up to 3 stops slower then normal with no perceptible increase in image blur. The IS function helps with low light conditions, fast paced scenes and shooting from moving vehicles.
Fast, quiet auto focus
A ring USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive responsive, near-silent high speed auto focus. Full time manual focus override is available without having to switch out of AF.
Super Spectra coatings
Optimised Super Spectra lens coatings and lens element shaping suppress flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help achieve true colour balance and increase contrast for vivid high definition images.
Passes distance information to E-TTL II
The lens passes distance information back to the camera's E-TTL II flash system to ensure optimal flash metering in any shooting situation.

Built on the same ergonomically improved design as the 055XB, the 055XDB is lightweight, sturdy and portable. This basic tripod has the same design as the 055XB but with a simpler centre column (no short column available) and more traditional locking knobs. With the leg angle presets, allow the camera to reach all intermediate heights from min-max extension.
Developed specifically to support the latest prosumer and professional light, compact HD camcorders, the 701HDV offers an updated design, which has been created for improved ergonomics with locks and knobs that allow for a more solid grip and better control, a better fluidity thanks to improved internal fluid cartridges, a double pan-bar rosette and a bigger sliding plate to optimize the position of the camera considering its centre of gravity.
The Kata DR-466 Digital Rucksack features a unique TST RIB structural protection for two D/SLR’s with mounted lens, 3-4 lenses, flash etc. + personal gear and a laptop.
By removing the padded bottom camera insert you can easily convert this rucksack from a camera bag to a daypack when not shooting.
The main compartment holds a D/SLR in top grip position while the modular dividers system will separate, organize and protect lenses, flashes and other accessories to suit your particular needs.
The dedicated rear padded compartment will protect a laptop or hold paperwork.
The large top compartment will hold personal gear or additional equipment, and the internal pockets and mp3 player pouch will allow you to organize your personal effects as efficiently as your photographic gear.
Ample external pockets allow quick zippered access to supplies and a water bottle/ tripod support pocket pulls out from a side pocket.
Included rain cover folds neatly away into an integrated pocket and can be hung out to dry on the small buckle next to the handle, or tucked away for storage in one of the pockets.
When carrying, a chest belt and balancing waist strap are available for ultimate comfort, and the rucksack is also compatible with the Kata Insertrolley if wheel along transportation is needed.
