The Sigma 500mm F4 DG OS HSM Lens for Nikon incorporates Sigma’s latest technologies and delivers a full range of advanced features and functions: enhanced dust and splash-proof construction, Optical Stabilizer (OS) system, SIGMA Tele Converter compatibility, AF function switch, SIGMA’s latest-generation Hyper Sonic Motor (HSM), and more.

Enhanced dust/splash-proof construction
Designed for top performance in tough shooting conditions, the SIGMA 500mm F4 DG HSM | Sports features highly effective dust- and splash-proof construction. The front of the lens features a water- and oil-repellent coating that allows water to be wiped away easily and helps prevent oil from sticking to the surface. This feature is particularly useful when shooting in a drizzle or near ocean spray.

Magnesium alloy barrel
To help minimize the weight associated with a hyper telephoto lens, the lens barrel is made with a magnesium alloy. Both lightweight and tough, this alloy contributes to the outstanding maneuverability of SIGMA 500mm F4 DG HSM | Sports.

Tripod socket with 90° click stops
Since photographers often prefer to use a hyper-telephoto lens with a monopod or tripod, the lens features a large and extremely stable tripod socket. Antistatic nickel plating on the socket parts help enhance the quality and durability of the 90° click stops, which make it easy to switch between vertical and horizontal shooting positions. The click position may be cancelled by turning off the “de-clicking” switch. The lens also comes equipped with a dedicated strap for the tripod socket, making it easy to carry equipment without undue stress on the camera mount.

Top-level optical performance
The lens incorporates two FLD and one SLD glass elements, while the optimized power distribution helps minimize spherical aberration and axial chromatic aberration. The optical system also effectively minimizes transverse chromatic aberration, which can affect the edges of the shots taken in the telephoto range. In addition, image quality remains exceptional when the lens is used with a SIGMA Tele Converter.

OS system with acceleration sensor and new Intelligent OS algorithm
The Optical Stabilizer (OS) system features an acceleration sensor to deliver even more precise performance and up to approximately four stops of stabilization. Two OS modes are available: Mode 1 for general photography and Mode 2 for motor sports and other applications requiring panning. In Mode 2, the acceleration sensor teams up with the Intelligent OS and its updated stabilization algorithm to deliver effective stabilization while you move the camera horizontally, vertically, or diagonally, regardless of the position of the lens.

AF function switch with preset AF modes
The AF function switch allows you to set your own autofocus specification. The lens can remember the focus position of your choice or turn off AF until it is needed. In addition to AF/MF, MO (Manual Override) is incorporated as one of the options of the focus mode switch. By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF. With AF position, standard full-time manual focus is available.

Quieter and Faster Optimized AF
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF. With the further enhanced AF algorithm compared to previous models, continuous AF (AF-C) improves the focusing efficiency.
