Canon EF-S 17-55mm F/2.8 IS USM
The Canon EF-S 17-55mm f/2.8 IS USM is an APS-C lens with a full frame equivalent focal length of 27-88mm. This comes very close to the versatile 24-70mm. With this effective focal range, it is a powerful zoom lens that delivers outstanding image quality for the serious photographer or videographer. The lens is ideal for landscape photography, and you can photograph large groups of people without having to step too far back. You can also capture stunning skylines and street scenes with more depth and dynamism. The lens has a fixed maximum aperture of f/2.8 across the entire range, which makes it extremely well suited to the semi-professional user. With the wide aperture, your subject gets the attention it deserves. Play with the depth of field and create beautiful blurred backgrounds. The wide aperture also delivers excellent results in low-light conditions. The aperture stays constant across the entire focal range.
The built-in Image Stabilizer ensures sharp, natural-looking shots by compensating for camera shake or a lack of light. This piece of engineering makes the lens extremely well suited to handheld shooting. The lens offers 3 stops of image stabilisation. IS helps you in low-light situations, during fast scene changes and when shooting from moving vehicles, among other things.
The Ultrasonic Motor works hard, yet inaudibly, to deliver the super-fast autofocus. USM uses ultrasonic frequency vibrations for super-fast, whisper-quiet focusing. High motor torque stops the focusing group precisely without overshooting. "Full-time" electronic manual focus override is possible without switching off the AF.
Optimised Super Spectra lens coatings and the special shape of the lens elements suppress flare and ghosting, which occur more often with digital cameras because of reflections from the image sensor. The coatings also help to achieve the right colour balance and increase contrast for lifelike, natural-looking photos.
Finally, the lens passes distance information to the camera's E-TTL II flash system, ensuring optimal flash metering in every shooting situation. All this makes the Canon EF-S 17-55mm f/2.8 IS USM a great addition for any camera with an EF-S mount.
Please note! This lens is not suitable for full frame cameras.
