PMA09: Sigma Announces 50-200mm F4-5.6 DC OS HSM

The Sigma Corporation is pleased to announce the new SIGMA 50-200mm F4-5.6 DC OS HSM. This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function.

Sigma 50-200mm F4-5.6 DC OS HSM

The lens incorporates SLD (Special Low Dispersion) glass in the front lens group 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 approximately 4 stops slower than normal for steady, handheld photography.

For Sony and Pentax mounts he built-in OS System operates in conjunction with a camera body equipped with an anti-shake function 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 110cm (43.3 inches) throughout the entire zoom range and a maximum magnification ratio is 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters.

This is currently one of the most affordable Super-Telephoto lens by Nikon. If this lens was announced 8 years ago, I will not pay any attention at all because at then DSLRs’ ISO1600 was mostly a marketing strategy and was only good for Black and White prints. These days, for amateur photographers, f5.6 coupled with any midrange DSLRs’ ISO3200 or even ISO6400, one will be able to get a decent shutter speed for wildlife or sports photography.

Nikon released their D600 replacement, namely the D610 which adds yet another full frame (FX) model to its shelf. There is not much difference in comparison with the older D600. What we hope is really that what happen with D600 sensor, does not happen here.

Following are some official sample photos from Nikon exclusively for the 24 Megapixel FX D610:
