It's packed with Sigma's technological goodies, including Optical Stabilization and Hypersonic autofocus motor and will be available in Sigma, Canon, Nikon, Pentax and Sony mounts.

Pre-PMA 2008: Sigma has announced an optically stabilized 120-400mm f/4.5-5.6 lens. The lens will be available for owners of Sigma, Canon, Nikon, Pentax and Sony DSLRs. A maximum magnification of 1:4.2 also makes it useful for users who want to get a little closer. The DG designation means the lens will work equally happily on 35mm or APS format SLRs.

The last time we heard anything about the long-delayed Sigma DP1 compact camera was back in November last year, when Sigma announced that they were going back to the drawing board. Now the company has published a teaser advert for the DP1 with the immortal tagline, “The worldwide debut, soon”.

Mini-review: Sigma 10-20mm f/4 DC So, now that I’m back writing these things, there are two reviews to be done, and where better to start than with the Sigma 10-20mm f/4 DC I got way back in August. The 10-20mm is an ultra-wide-angle for small-frame Digital cameras, giving about the same field of view as a 16-32mm would conventionally. Typical uses of this range are for architectural and landscape photography along with gritty street photography and photojournalism. Over at InPhotos this l

Sigma announces the new 18-200mm F3.5-6.3 DC for Nikon mount cameras. The compact and lightweight construction of 70mm in diameter, 75.6mm in length and 395g makes it ideal for field work. This lens has a minimum focusing distance of 45cm (17.7") and a maximum magnification of 1:4.4. An inner focusing system also eliminates front lens rotation, making the lens particularly suitable for using the petal lens hood and circular polarizing filters. A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight...

Sigma has announced that it is to make its unstabilized 18-200mm F3.5-6.3 DC lens compatible with Nikon's D40 and D40x SLRs which lack an in-body focus motor. Previously 'screwdriver' driven, the new lens will sport an integral motor to shift the glass around and will sit aside the 18-200 OS in Sigma's 2008 range. Making up for the lack of stabilization is the reduction in size and weight - over 24 mm (0.9 in) of length and a handy 215g (7.6 oz) of weight have been lost compared to its big brother which wasn't exactly obese to begin with. Pricing and availability are yet to be announced.

A new version of the Sigma 18-200mm F3.5-6.3 DC Lens is compatible with the Nikon D40 and D40x DSLR cameras. 

Sigma Photo Pro 2.3 includes new image processing code, which provides better auto white balance performance.

The Sigma DP1 prototype was shown off at Photokina in October 2006. Many people have been anxiously awaiting this camera as it would be the first compact camera to feature a much larger sensor than other compact cameras. However, in an announcement today, the COO of Sigma apologized for the delay and let everyone know that some of the DP1 specifications that were previously announced will be changing.

The Sigma DP1, the world's first digital compact camera featuring an APS-C sized imaging sensor, was first presented as a concept prototype at Photokina 2006. Since then prospective users have nervously been waiting for its release to ...

In today's press release, Kazuto Yamaki, the Sigma Chief Operating Officer, explains that during the DP1 pre-beta product development stage early in the summer, it proved difficult to achieve the required image quality. It was decided to make some product changes and the DP1 should be moving in the right direction now, although a new ship date is not yet given...

Sigma announces two fisheye lenses for exclusive use with APS-C size digital SLR cameras. The 4.5mm F2.8 EX DC Circular Fisheye HSM lens is an circular fisheye autofocus lens with an angle of view of 180°, a minimum focusing distance of 13.5cm / 5.3 inch and a maximum magnification of 1:6. The 10mm F2.8 EX DC Fisheye HSM lens has a diagonal angle of view of 180° for Nikon (154° Sigma, 167° Canon). The minimum focusing distance is 13.5cm / 5.3 inch, and the maximum magnification is 1:3.3...

The other type of fisheye lens available is the diagonal variety which squeezes a 180° angle of view into a standard rectangular format. This new 10mm F2.8 EX DC Fisheye HSM from Sigma is just such a lens. That said, it captures a true 180° vista only when mounted in front of a Nikon DX sensor - users of Canon and Sigma DSLRs make do with 167° and 154° respectively. A built-in lens hood and HSM focusing are here and the lens will focus down to 1.8cm (0.7 in) from the front surface of the lens giving a reproduction ratio of 1:3.3.

Sigma has for the first time marketed a true fisheye optic for crop sensors, projecting a circular 180° image onto APS-C sensors. The new lens sports a focal length of 4.5mm and maximum aperture of f/2.8, HSM silent focusing and SLD low-dispersion lens elements. Aside from the 'edgy' skateboarding shots and frankly unflattering portraits often seen, circular fisheyes are actually quite useful for astrophotography and scientific applications. Pricing and availability is yet to be announced.

A selection of Sigma 150mm f/2.8 EX DG HSM Macro Lens sample pictures are now online.

10-20mm F4-5.6 EX DC HSM lens allows super wide-angle photography and is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras.
