Sigma 500mm F4 DG OS HSM (S) Nikon Fit

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. The lens is compatible with the exclusive SIGMA Protector LPT-11 (sold separately), which effectively helps prevent damage to the lens during shooting and maintenance.

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.

The lens hood is made of carbon fiber, which is both lightweight and strong. In fact, the entire lens is designed to be lightweight for outstanding performance in tough shooting conditions.

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens

The lens for the Nikon camera includes the electromagnetic diaphragm mechanism and is able to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

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 fine-tuned by “de-clicking” with the press of a button and manually adjusting the lens. 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.

Transverse chromatic aberration, which can be an issue in the telephoto range at the edges of images, has also been effectively minimized.

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 (sold separately).

Circular PL Filter RCP-11 is a drop-in filter that can easily be rotated while the lens is in use. (A WR Protector filter that is inserted in a slot at the rear of the lens comes with the lens as standard equipment.)

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain.To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.

A maximum concentration of functions that delivers top-level optical performance and outstanding maneuverability.

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. Using the optional SIGMA USB DOCK, it is possible to adjust the MO position’s sensitivity to switch to manual focus.

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. Note: Image is for SIGMA mount lenses. Available switch functions may vary by mount.

The Optical Stabilizer (OS) function features an acceleration sensor to ensure even higher precision. 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. This feature helps ensure effective panning and outstanding capture of moving subjects.

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.

Use higher telephoto magnification while using AF. Make fine adjustments to the point of focus and OS system. Use your valuable lens asset with a different camera body. SIGMA responds to photographers’ needs with top-level functionality!

For our new product lines, we have developed exclusive SIGMA Optimization Pro software that allows the user to update the lens firmware and adjust focus position and other parameters. The user will be able to connect the lens to a computer with a special SIGMA USB DOCK and use easy-to-operate on-screen controls to create personal lens specifications.

Tele Converters that are newly designed to match the new lens line-ups (optional) can be attached. The addition of SIGMA’s TELE CONVERTER TC-1401 or TELE CONVERTER TC-2001 produces a AF 700mm F5.6 hyper-telephoto lens or a AF 1000mm F8 hyper-telephoto lens respectively.

* When shooting subjects with low contrast or luminosity value, focus may not be spot on the subject.
