The Sigma 150-600mm f5-6.3 DG OS HSM Lens combines high portability and durability, this high-performance hyper-telephoto zoom lens from Sigma's Sports line features superb build quality with dust-proof and splash-proof construction.

• Dust and splash-proof
• Zoom lock at every focus distance
• Water-repellent coating
• Compatible with Sigma tele converters
• New OS system with accelerometer
• Easily accessible manual over-ride switch
• Optimized auto focusing
• Telephoto shooting at 600mm
• Minimized chromatic aberration for higher optical performance

By incorporating excellent optical glass elements, it minimises chromatic aberration and achieves class leading image quality.
This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, and 3 SLD (Special Low Dispersion) glass elements, and compensates for colour aberration at the utmost. Chromatic aberration in particular, which could be visible especially towards the telephoto-end even when stopped down, is corrected by the optimised design of glass elements including FLD lenses.

Dust-proof and splash-proof construction
The lens is Dust and splash-proof and designed for higher durability. It is able to meet the demands that professional photographers require in challenging shooting conditions, such as in the rain.

Zoom lock switch can be set at any focal length
The new zoom lock switch enables the zoom ring to be locked at any focal length. It can be fixed at the photographer’s desirable focal length, which allows stable shooting whether the lens is positioned upward or downward. It also helps during long exposure photography.

Water and oil-repellent coating ensures a pleasant photography experience
Forefront and rear lenses incorporate a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

Manual override incorporated to make two full-time manual modes switchable.
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.

Newly designed tripod socket enables desirable fixing
The tripod socket is newly designed since hyper-telephoto zoom lenses like this one which has 600mm telephoto-end often need a monopod or tripod for shooting. While ensuring that the tripod socket is large and stable, it’s possible to click the position at every 90゜to make the change of shooting position from and to vertical and horizontal much easier. By attaching the supplied strap, the lens can be carried safely without putting unnecessary pressure on the mount of the camera.

Offering excellent usability as a straight zoom
This lens is optimised to allow the lens front to expand/contract smoothly in order to immediately adopt without adjusting the holding position, even to a sudden change in angle-of-view. The lens front is designed to ensure easy handling in such situations.
