This super telephoto 500mm f/4 prime lens is designed for full-frame format Sigma SA-mount cameras, and can also be used with APS-C models where it will provide a 750mm equivalent focal length.

A relatively fast f/4 maximum aperture provides excellent illumination for a lens of this focal length.

One SLD and two FLD elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity, and contrast regardless of focus point or aperture setting. This optical design also helps to control distortion and limit vignetting.

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.

The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. A dedicated switch on the barrel of the lens provides multiple AF modes, including a focus recall setting and AF off. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. Two manual focus modes are available, the standard AF/MF option and an MO setting that switches the lens into manual even during continuous AF.

Optical Stabilizer system can compensate for approximately 4 stops of shutter speed for sharper images. Two modes are available, one for general use and one for panning, which uses Intelligent OS for more effective panning in any direction.

Compatible with Sigma Global Vision Teleconverters, this lens can be extended into a 700mm f/5.6 lens with the 1.4x teleconverter or a 1000mm f/8 lens with the 2x teleconverter.

A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.

Drop-in filter system works with 46mm filters. An optional RCP-11 Circular Polarizer filter is designed specifically for the lens and can be rotated while it is inserted.

The lens barrel is constructed using a magnesium alloy that is lightweight and durable, which allows this lens to perform in a wide range of situations.

The bayonet mount is constructed from brass for ensured accuracy and durability.

The lens hood is made of carbon fiber, a lightweight but strong material that will perform in tough conditions.

A rotating tripod foot helps keep this lens secure during shoots and features antistatic nickel plating to improve durability. It features click stops every 90° and can be turned off with a de-clicking switch for smooth movement. The lens also comes with a dedicated strap for the tripod foot which limits strain on the camera mount.

Dust- and splash-proof construction with rubber sealing to protect the mount and a water- and oil-repellent coating on the front and rear elements.

This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

Q: 1. Is the manual focus mechanical (the ring is physically linked to the moving elements) or focus-by-wire (moving the ring tells a motor how to move the elements)?

A: The lens uses a Hyper Sonic Motor to move the elements. It is focus by wire.

Q: 2. Will this lens autofocus with a sigma 1.4 teleconverter when adapted to a Sony A7R3?

A: The answer depends on the EF to E mount adapter. One answer is no, you cannot use the 500mm f/4 and the Sigma 1.4 teleconverter and mounting to the camera with the Sigma MC-11 EF to E-mount adapter since that device does not work with any teleconverter. The second answer is not known for there are no reports of using the Sigma 500mm f/4 with the Sigma 1.4 teleconverter using a Metabones EF to E mount adapter on a Sony a7 R III at this time.

Q: 5. Does this lens focus as fast as the Nikon 500mm?

A: I used this lens for few days before I returned it to BH. The lens AF is slower than Nikon's equivalent. It is also very inconsistent from shot to shot. I used to own the 600 f/4G and currently have the 800mm FL VR. AF accuracy and consistency from both of these lenses is better than the Sigma 500 OS. The Sigma does not respond to the different settings of the AF delay custom function.
