EF-S 18-55mm f3.5-5.6 IS
Canon strengthens its EF-S series of lenses with the launch of the EF-S 18-55mm f/3.5-5.6 IS. The lens is one of the first in the EF-S series to incorporate a 4-stop Image Stabilizer, dramatically extending low-light performance. The lens incorporates an aspherical lens element to achieve exceptional image clarity.
The lens is built to fit exclusively on those EOS cameras with an EF–S lens mount – including the new EOS 40D, EOS 30D, EOS 400D and earlier models.
The EF-S 18-55mm f/3.5-5.6 IS is a lightweight general-purpose zoom lens that is ideal for handheld photography in a wide range of lighting conditions. Offering high optical quality, the lens has an 11 element, 9 group construction, including one aspherical element for crisp corner-to-corner detail. The lens maintains a closest focusing distance of just 25cm throughout the zoom range, giving photographs the flexibility to frame up close when needed.
4-stop Image Stabilizer
Canon’s latest optical Image Stabilizer (IS) technology provides up to 4-stop compensation for image blur caused by camera shake and slow shutter speeds. Photographers normally shooting handheld at 1/250 sec can switch on IS to obtain a similarly steady and blur-free result with a shutter speed of just 1/15 second. The inclusion of automatic panning detection makes it easier for photographers to track wildlife and other moving subjects. To ensure consistently accurate results at all zoom positions, the IS system within each lens has been optimised for that lens’ specific focal length range. Since the IS system is based within the lens, the results are visible through the viewfinder when framing the image.
Appealing background blur
The lens incorporates a circular aperture. This helps create an even background blur when depth-of-field is minimised, giving photographers more creative options for portraiture and similar types of photography.
Super Spectra coatings
Canon’s patented Super Spectra coatings are used to suppress flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.
E-TTL II flash integration
The lens transmits distance information to the E-TTL II flash system of all current model digital EOS cameras, improving flash exposure metering when used in conjunction with Canon’s range of EX Speedlite flash units.
In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.
