The Sigma 10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras.

This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm (9.4») at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently.

• It covers a superwide angle of view 102.4° to 63.8°(SD format)
• Three pieces of Special Low Dispersion (SLD) elements and three aspherical lens elements produce top quality optical performance.
• Inner focusing system ensures the length of the lens remains unchanged whilst controlling aberrations.
• Equipped with HSM (Hyper Sonic Motor) system
• Minimum focusing distance of 24cm (9.4») at all focal lengths.
• Relatively compact, lightweight for an ultra wide-angle zoom lens.

Canon EF-S 17-55mm f/2.8 IS USM

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.

f/2.8 aperture throughout zoom range
3-stop Image Stabilizer
Fast, quiet auto focus
Super Spectra coating
Circular aperture for pleasing background blur

Optional lens hood

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 add 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 use of shutter speeds up to 3 stops slower with no perceptible increase in image blur. IS 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. Good holding torque stops the focusing lens group with precision without overshoot. 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 hi-fidelity 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.
