Canon strengthens its EF-S series of lenses with the launch of the EF-S 18-55mm f/3.5-5.6 IS. With an equivalent focal length of 29-88mm, the new Canon lens is the first in the EF-S series to incorporate a 4-stop Image Stabilizer, dramatically extending low-light performance. The Canon EF-S 18-55mm IS lens incorporates specialist optics to achieve exceptional image clarity - the EF-S 18-55mm f/3.5-5.6 IS employs an aspherical lens element. The Canon EF-S lens is built to fit exclusively on EOS cameras with an EF–S lens mount - including the new EOS 40D, EOS 30D, EOS 400D and earlier models. Keeping Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.

Canon EF-S 18-55mm f/3.5-5.6 IS
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.

Canon EF-S 18-55mm lens - Optical 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.

Canon EF-S lens - Appealing background blur
The Canon EF-S 18-55mm IS lens also 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.

Canon EF-S 18-55mm lens - Super Spectra coatings
The Canon EF-S f/3.5-5.6 IS employs Canon’s patented Super Spectra coatings 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.

Canon EF-S IS lens - E-TTL II flash integration
The new Canon EF-S 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.

IFA NEWS 2017 REPORT - The IFA International Consumer Electronics Show took place every two years, but since 2006 the IFA show became once again an annual event under Berlin’s famous Funkturm landmark. In the early days, back in 1924 the IFA began in Berlin as the “Great German Radio Exhibition”. In the meantime, the International Consumer Electronics Show has not only become the world's biggest trade show for consumer electronics but also presents the world's largest number of product premieres in consumer electronics and home appliances. At IFA 2009 more than 3 billion Euros worth of orders were generated. IFA 2010 could even surpass this number! The total number of exhibitors at last year’s IFA show was 1164 from 46 countries. The total number of trade visitors was 134194 from 105 countries, quite amazing numbers. The IFA 2010 show news will come to you live from the show floor, so stay tuned!
