APO 50-500mm F4.5-6.3 DG OS HSM

High ratio ultra telephoto zoom lens covering from standard range of focal lengths to telephoto and incorporating Sigma's original OS function

This ultra telephoto zoom lens covers a standard range of focal lengths from 50mm to 500mm ultra telephoto range. This lens is equipped with Sigma’s unique OS (Optical Stabilizer) function. This system enables hand held photography for many types of subjects such as motor sports, air planes, macro and wildlife. Four SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration throughout the entire zoom range. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual focus override. The addition of the optional APO TELE CONVERTER produces a 1000mm ultra telephoto zoom lens.

Covering a range of focal lengths up to ultra telephoto

This lens is ideal for many types of photography such as motor sport, air planes, macro and wildlife. By rotating the zoom ring, it is possible to change the focal length easily from a standard focal length to an ultra telephoto range. This lens has an equivalent angle of view of a 75-750mm lens * when used on digital cameras with APS-C size image sensors.

*The angle of view varies depending on which camera the lens is mounted on.

Sigma's own unique OS (Optical Stabilizer) technology

The lens is equipped with Sigma’s own unique OS (Optical Stabilizer) function. This system offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, making telephoto shooting easy. Mode 1 is ideal for general photography and Mode 2 is designed for panning subjects such as racing cars. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an anti-shake function. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement.

*For Pentax and Sony mounts, it is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax
*ist series and K100D.
*When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera’s stabilizer unit off.
*This lens cannot be used with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v.

Excellent Optical Performance

This lens features four SLD (Special Low Dispersion) glass elements, providing excellent correction of color aberration throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting and ensures high contrast images. This lens is equipped with a read focus system that minimizes fluctuation of aberration caused by focusing. High image quality is assured throughout the entire zoom range.

The close focusing capability

This lens has a maximum magnification of 1:3.1 (at the focal length of 200mm). It enables photographers to get close up to small subjects and eliminate distracting parts of larger subjects.

HSM (Hyper Sonic Motor)

The rear focus mechanism and HSM (Hyper Sonic Motor) ensures quiet and high speed AF as well as full time manual focus capability.

*AF will not function if the Sony and Pentax camera bodies do not support HSM.

APO Tele-Converter (Optional)

The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8.8 MF ultra-telephoto zoom lens or a 100-1000mm F9-12.6 MF ultra-telephoto zoom lens respectively.

* The Pentax mount Tele Converter is not compatible with this particular lens.

Hood Adapter HA1030-01 (Supplied)

Hood adapter extends the length of the lens hood and provides more effective shading when used with digital cameras with an APS-C size image sensor.

* When using the APS-C Hood Adapter HA1030-01 with digital cameras with larger than APS-C size image sensor, vignetting will occur. Please remove the hood adapter if you are using these cameras.

Easy Operation and Handling

This lens features a Zoom Lock device to eliminate “Zoom Creep” when the lens is tilted down. When the lens is set to the 50mm focal length, it is remarkably compact and provides easy handling. A removable tripod socket (TS-31) is included, which is convenient for handheld photography. The Rear Focus mechanism makes it possible to use the custom bayonet “Petal-type Hood”, which prevents extraneous light from degrading the image quality. The filter size of this lens is Diameter 95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an Diameter 86mm filter.

*It is not possible to use a Polarizing filter with the step down ring. If you attach a Polarizing filter, you may not be able to remove it from the lens again.

In the news

‘In terms of specifications, the Sigma 50-500mm must surely be the ultimate telephoto zoom. The 10x zoom range is impressive enough, but the Optical Stabiliser completes the package. This is a solid, well-finished lens with smooth, positive controls and not a hint of play or wobble anywhere. The Sigma 50-500mm does an awful lot for the money and is well worth the investment.’

‘For the price you expect the build quality to be first-class and the good news is, it is! The zoom and focus rings offer plenty of grip; the zoom extended smoothly to its maximum 500mm range and can be locked at 50mm to prevent zoom creep. For such a big zoom it felt surprisingly well-balanced, too. Image quality tests revealed sound levels of sharpness at 500mm. Fringing was also well controlled…’

‘I do a lot of action photography with aviation subjects, and I know how hard it can be to find a lens that delivers consistently on such a demanding subject. This sigma tracked the aircraft very well, and the hit rate of sharp images was around 50{a85d0d947998bd8b1b3f988fbc98eccd45f806e38d75dfa20c8c560f6f1da76e}, which is as good as my own Canon 100-400mm delivers. This is not the cheapest lens you will consider adding to your camera bag but it may well prove to be on of the best investments. The performance is very good, especially for the price. You get versatility and a performance that will ensure you get some excellent images.’

‘The optical stabiliser has made a big difference, cutting camera shake and making it far easier to compose accurately at full zoom while handholding the lens. The 10x zoom offers a wide range of compositional choice. You can crop in tightly on details, and the shallow DOF at long zoom settings gives pleasing effects. For a giant lens, the Sigma has a remarkably ‘wide’ minimum focal length of 50mm, making it very versatile- step back a few paces and you can capture normal subjects.’

‘The lens is well engineered and of solid construction. By many standards, this is a spectacular lens with one of the largest (if not THE largest) zoom ranges around in DSLR photography.’

‘With a 10x focal length range, Sigma’s 50-500mm lens truly deserves to be called a ‘super-zoom’. Focusing is both quick and quiet. Optical stabilisation is not just a nice addition but an essential feature in such a lens.’

‘Distortions, chromatic aberrations and vignetting are surprisingly well controlled, considering the extraordinary zoom range. In our tests, sharpness and contrast were impressive right up to the maximum 500mm focal length, matching the overall optical quality of the other Sigma lenses in the group.’

‘The main claim to fame of this lens is that it offers a mighty 10x zoom range, stretching all the way from a ‘standard’ 50mm focal length to a super-telephoto 500mm. At the long end, it could therefore match the longest super-tele zooms on the market from Sigma and Tamron, while playing into the hands of photographers who hate swapping lenses’. (2015)

‘Our test sample delivered impressively sharp, crisp results even at maximum apertures, through the zoom range.’
