Canon EF-S 17-55mm F2.8 IS USM - Lens

With its constant f/2.8 aperture across the entire focal length range, and an image stabilizer whose effect is equivalent to a gain of three shutter speeds, the EF-S 17-55mm f/2.8 IS USM lens ensures exceptional performance and framing flexibility in low-light conditions.

High-performance wide-angle zoom
With a focal length range of approx. 27-88 mm (24×36 equivalent), the EF-S 17-55 mm f/2.8 IS USM is a powerful standard zoom that guarantees outstanding image quality. Its wide-angle section lets you capture more of the scene, adding space and perspective to framing.

Fixed aperture
The large f/2.8 aperture guarantees excellent results in low-light conditions. This aperture remains constant across the entire focal length range, enabling zooming from 27 to 88 mm (24×36 equivalent) without any reduction in shutter speed.

Aesthetic background blur
An almost circular aperture ensures an aesthetic background blur when shooting with a large aperture, ideal for isolating the main subject from the background.

Image stabilizer
The EF-S 17-55 mm f/2.8 IS USM lens features Canon's Image Stabilizer (IS). Ideal for hand-held shooting, the Image Stabilizer allows a gain of three shutter speeds, thus reducing the risk of perceptible camera shake. The stabilizer makes it easier to shoot in low-light conditions, when the subject is moving fast, or when shooting from a moving vehicle.

Fast, silent autofocusing
The Ultrasonic ring motor (USM) operates on the principle of ultrasonic frequency vibrations, resulting in extremely fast autofocusing with almost silent operation. This high-torque AF motor stops the focusing lens group without inertia or hesitation. Users can quickly switch from autofocus to manual focus, and even retouch the autofocus point permanently without having to disengage autofocus mode first.

Super Spectra coating
The Super Spectra coating and optimized lens shape eliminate the risk of internal reflections and ghost images, which can occur with digital cameras due to the potential reflection back from the sensor. This treatment also delivers natural color balance and enhanced contrast for vivid, true-to-life images.

Transmitting distance information to the E-TTL II system
The lens transmits camera-to-subject distance information to the body's E-TTL II flash system to ensure optimum flash exposure metering, whatever the shooting situation.
