Sigma 50-200mm f/4.0-5.6 DC IF SLD Optical Stabilized (OS) Lens with Hyper Sonic Motor (HSM) for Canon Digital SLR Cameras

This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens groups and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady handheld photography. For Sony and Pentax mounts the built-in OS System allows the photographer to see the stabilized image in the viewfinder and can be used as an alternative with cameras having built-in image stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This lens has a minimum focusing distance of 43.3inches (110cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.5. An inner focusing system eliminates front lens rotation making it suitable for use with circular polarizing filters.

The Nikon mount AT-X 124 PRO DX II has a built-in AF motor drive. The motor inside the lens was loaded onto the Nikon mount specification anew. The AF operates smoothly and quietly due to a DC motor that uses a new AF control gear assembly. With the built-in motor the lens can be used in AF mode with the Nikon D60 and D40 and other silent wave bodies.
The Canon version of the lens already has a built-in AF motor and will benefit from the improved multi-coating.
The optical system of original AT-X 124 PRO DX won awards for its sharpness world-wide. This design was maintained in the AT-X 124 PRO DX II and improved with the introduction of new multi-coating_ system. The new multi-coating helps reduce reflections that can cause flare and ghosting even more than in the AT-X 124 PRO DX.
The AT-X 124 PRO DX II features the one-touch focus clutch mechanism. _ To use the one-touch focus clutch mechanism move the focus ring forward towards the front of the lens for AF or back for MF. This allows for a fast and easy manual over-ride in difficult lighting situations.
