Press Release:

The Sigma Corporation is pleased to announce the new 70-300mm F4-5.6 DG OS. This telephoto zoom lens incorporates Sigma’s original OS (Optical Stabilizer) function and is housed in a compact construction. The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. It makes telephoto shooting easy for many types of photography such as sport and nature. 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. The SLD (Special Low Dispersion) glass element provides excellent correction for all type of aberrations. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the focal range. The lens has an overall length of 126.5mm (5.0”), maximum diameter of 76.5mm (3.0”) and weight of just 610g. Its compact construction makes it convenient for travel and hand held telephoto photography. This lens’ rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the photograph. This lens has a minimum focusing distance of 150cm (59.1”) throughout the entire zoom range and a maximum magnification ratio of 1:3.9, making it ideal for close-up photography.

Press Release:

The Sigma Corporation is pleased to announce the launch of new SIGMA 18-250mm F3.5-6.3 DC OS HSM.
The SIGMA 18-250mm F3.5-6.3 DC OS HSM incorporates Sigma’s original anti-shake compensation function, with a 13.8 times zoom ratio. As opposed to having an anti-shake function in the camera body, this lens’s Hybrid Optical Stabilizer provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens. Incorporating four Special Low Dispersion glass elements and three aspherical lens elements provides excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1: 3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood. Incorporating super multi-layer coating reduce the ghost in the backlight photography.

The Sigma Corporation is pleased to announce the new 50-200mm F4-5.6 DC OS HSM. Compact, High Performance Telephoto Zoom Lens.
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.
