The EF 70-300 mm 1:4-5.6L IS USM is a powerful telephoto zoom lens from Canon's professional L-series. It impresses with a wide focal length range, excellent image quality, and a compact, robust design. With a focal length range of 70-300 mm, it is a compact and versatile telephoto zoom lens that delivers exceptional image quality. It is ideal for wildlife and sports photographers, as well as photojournalists and portrait photographers. The professional L-series models are Canon's most powerful lenses, representing precision-crafted EF optics of the highest quality. They offer excellent imaging performance, top-notch handling, and are well protected against dust and splashes. The optical image stabilizer, which allows for shutter speeds up to 4 stops longer, has been specifically tailored to the lens's unique focal length range. It minimizes motion blur that can occur when shooting without a tripod or using a long exposure time. The automatic detection of camera panning ensures that intentional pans during subject tracking are not mistakenly interpreted as camera shake. Since the image stabilizer is integrated into the lens, the photographer can see and check the final image quality through the viewfinder. The inclusion of two UD lenses nearly eliminates chromatic aberrations, resulting in excellent image quality and sharpness.
