Canon Ultrasonic EF500mm f 4L IS II USM Specification

The Canon Ultrasonic EF 500mm f/4L IS II USM Lens is a high-performance telephoto lens designed for professional photographers who demand superior image quality and reliability. It features a robust construction with advanced optical elements to provide exceptional clarity and sharpness across the frame. The lens incorporates a sophisticated Image Stabilization (IS) system offering up to four stops of correction, ensuring steady shots even in challenging lighting conditions. The Ultrasonic Motor (USM) enables fast, precise, and quiet autofocus, enhancing performance for wildlife and sports photography.

The optical design includes fluorite and Super UD lens elements that minimize chromatic aberrations and color fringing. With a maximum aperture of f/4, the lens delivers excellent performance in low-light situations while allowing for a shallow depth-of-field, creating impressive background blur for subject isolation. The use of Canon’s proprietary SubWavelength Coating (SWC) reduces ghosting and flare, contributing to high-contrast, high-resolution images.

The lens is part of Canon's esteemed L-series, known for its durability and weather-sealed construction, making it suitable for use in various environmental conditions. It is relatively lightweight for a super-telephoto lens, incorporating magnesium alloy components to reduce weight without compromising strength. Compatibility with Canon's range of extenders allows for increased focal length versatility, extending the reach while maintaining autofocus functionality with compatible DSLR cameras. The EF 500mm f/4L IS II USM is designed to meet the rigorous demands of professional use, combining state-of-the-art technology with Canon's commitment to optical excellence.
