The Sigma 18-50mm F2.8-4.5 DC OS HSM is a new standard zoom lens for DSLRs with APS-C / DX size sensors. It offers a large aperture of F2.8 at 18mm wide angle, faster than most standard kit lenses, and the HSM (Hyper Sonic Motor) ensures quiet and high speed auto-focusing.
This lens has a minimum focusing distance of 30cm (11.8 inches) throughout the entire zoom range and a maximum magnification ratio of 1:4.1.
The 18-50mm F2.8-4.5 incorporates Sigma’s Optical Stabilisation system, and compensation for camera shake is visible in the view finder, so the photographer can easily check for focus and subject movement. Coupled with the large aperture this function is ideal for indoor photography and in low lighting condition. For Sony and Pentax mount, the built-in OS function can be used even if the camera body is equipped with an anti-shake function.
High image quality throughout the entire zoom range is assured by two SLD (Special Low Dispersion) glass elements and three aspherical lenses. They correct for all types of aberrations. The Super Multi-Layer Coating, in its turn, reduces flare and ghosting.
Only the manufacturer warns that vignetting may occur if the lens is used with 35mm SLR cameras or digital cameras with image sensors larger than APS-C size.
The 18-50mm F2.8-4.5’s design incorporates inner focusing and inner zooming systems. It means that the overall length of the lens does not change during focusing and zooming, so handling is convenient. And the HSM (Hyper Sonic Motor) ensures a quiet and high speed AF.
The Sigma 18-50mm F2.8-4.5 DC OS HSM lens will be available in Sigma, Canon, Nikon, Pentax and Sony mounts.

What’s new: Photographyblog have posted the camera’s full review with sample images!
Photokina 2008 introduced compact digital camera Sigma DP2 which Sigma Corporation positions as direct successor of highly rated Sigma DP1. A camera is small and light enough to carry around everywhere, yet offering the technology for serious photography.
The DP2 has image processor True II, which is supposed to increase the speed of image processing and total efficiency and quality of shots. This photo processing engine leverages the texture and color of RAW files to deliver priceless images.
The APS-C sized sensor will deliver high resolution and rich tone. Besides, it is Sigma’s three-layered Foveon X3® direct image sensor, so I believe it captures all the color, creating images of unprecedented immediacy.
The DP2 features an integral standard lens that is brand-new and purpose-designed, with a focal length equivalent to 41mm in a 35mm camera.
Firmware Update:
Ver. 1.01:
Decrease the phenomenon of intermittent camera freeze under certain conditions.
The accuracy of the Auto Focus has been improved.
Camera Reviews:
Photographyblog.com:
The general operation and speed of the DP2 have been improved thanks largely to the new image processing engine and clever Quick Set menu, but don’t expect a quantum leap in performance from the turgid DP1.
