Sigma 500mm f/4.5 EX DG APO HSM Lens for Sigma DSLR Cameras

The Sigma 500mm F4.5 EX DG APO HSM Lens, designed for Sigma DSLR cameras, is a high-quality, professional-grade ultra-telephoto prime lens. Engineered for full-frame sensors, it can also be utilized with smaller APS-C size sensors, effectively increasing the focal length to approximately 750mm with most cameras. This versatility makes it an ideal choice for photographers seeking to capture detailed, high-resolution images of distant subjects, such as wildlife or sports events.

This lens boasts a unique 500mm focal length and a large fixed aperture of f/4.5, allowing for superior light intake and image quality, even in low-light conditions. The lens's Hyper Sonic Motor (HSM) ensures quiet, accurate, and high-speed autofocusing. This works in tandem with an Inner Focusing system, which enhances speed and responsiveness while maintaining the lens's overall length during focusing.

Despite its long focal length, the Sigma 500mm F4.5 EX DG APO HSM Lens is surprisingly compact, measuring approximately 14 inches in length and weighing just under 7 pounds. This makes it a reliable and durable choice for photographers on the go.

The lens incorporates two ELD (Extraordinary Low Dispersion) glass elements, providing optimum color correction and sharpness across the entire zoom range. A cutting-edge multi-layer lens coating technology and lens design formula work together to minimize flare and ghosting, ensuring crisp, clear images.

The lens also features rear insertion 46mm filters with provision for easy rotation of polarizing filters. It is compatible with Sigma APO Tele Converters, offering the potential for additional focal length as a 700mm F8 or 1000mm F11 lens. This versatility further enhances its appeal to professional photographers and hobbyists alike.
