The Sigma 70-300mm F4-5.6 DG OS is a new image stabilized telephoto zoom lens. Incorporating Sigma’s original OS (Optical Stabilizer), the 70-300mm F4-5.6 DG OS offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. The lens has an overall length of 126.5mm (5.0”), maximum diameter of 76.5mm (3.0”) and weight of just 610g, making it well-suited to travel photography. The Sigma 70-300mm’s rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the photograph and it has a minimum focusing distance of 150cm throughout the zoom range. The Sigma 70-300mm F4-5.6 DG OS will cost £399 and be available in late September for Sigma, Canon, Nikon, Pentax, and Sony cameras.

Sigma 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.

Lens Hood (LH 680-02) supplied

It might be quite interesting at $660, as long as the Sony 70-300 starts at about $730-740, with the widest aperture 4.5 (almost half a stop smaller than Sigma). Anyway, we must see what the guys from http://www.slrgear.com have to say, and only after that to make decisiones.

Very good contrast and sharpness. I’d say that this is a “sunny day” lens, but it has also performed admirably during heavy overcast days.
