Sigma 500mm f/4.5 D EX APO HSM Lens for Nikon F *USED*

The Sigma 500mm f/4.5 EX DG APO HSM is a specialized super-telephoto prime lens designed for the Nikon F-mount, offering a unique balance between extreme reach and manageable weight. Unlike the standard f/4 alternatives from other manufacturers, this lens utilizes a slightly smaller f/4.5 maximum aperture, which significantly reduces its overall physical footprint. This design makes it a favorite for wildlife and sports photographers who require the compression and magnification of a 500mm focal length but prefer a more portable setup for travel or handheld shooting.

Internally, the lens is built with an advanced optical formula that includes two Extraordinary Low Dispersion elements to maintain high contrast and minimize chromatic aberration. It features a Hyper Sonic Motor for fast and near-silent autofocus, which is essential when tracking moving subjects such as birds in flight or athletes on a field. The lens also employs an internal focusing system, ensuring that its physical length remains constant while focusing, which helps maintain balance when used on a tripod or monopod.

The barrel is constructed with a durable finish and includes a dedicated drop-in filter holder near the rear mount, allowing for the use of specialized 46mm filters that are difficult to mount on the large front element. It also features a focus limiter switch with three distinct ranges to optimize autofocus speed based on the subject distance. This lens remains a highly sought-after option for those seeking professional-grade telephoto performance in a relatively compact form factor that integrates seamlessly with both film and digital Nikon systems.
