Canon EF100-400LISII EF 100-400 f4.5-5.6L IS II USM, Diameter 77m

The second generation of one of Canon’s most popular professional lenses, the EF 100-400 f4.5-5.6L IS II delivers outstanding improvements in image quality, functionality and performance to meet and exceed the needs of professional and enthusiast photographers. The lens’s completely redesigned optical structure now features an improved 4-stop optical Image Stabilizer to reduce the effects of visible camera shake on long-distance shots, with three IS modes tailored to most typical shooting conditions, while Canon’s pioneering ring-type Ultrasonic Motor provides fast, silent autofocusing. Replacing previous linear type zoom construction, the new rotation type zoom ring enables improved handling for minute adjustments and excellent balance throughout the zoom range. Designed to be used anywhere, even in the harshest conditions, the lens continues the renowned L-series lens DNA and rugged construction. You can rely on the lens to perform in vastly challenging environments, with a dust and water-resistant construction providing the durability users demand. For added endurance, the lens features fluorine coatings on the front and rear lens elements, reducing the possibility of dirt sticking to the lens surface
