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.
Sigma today announced two new telephoto zooms - one for APS-C cameras and one for full-frame. The APO 50-150mm F2.8 II EX DC HSM uses no less than four SLD elements in its design to minimize aberrations and HSM focusing to keep the noise down. Internal focus and zoom ensure there is no change to the size of the lens during use. The APO 70-200mm F2.8 II EX DG MACRO HSM has a modified layout to improve close-up performance to make better use of the maximum 1:3.5 subject magnification ratio. Pricing and availability are to be announced but click though for specifications.
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 market - in vain. Sigma has today published an announcement in which the company explains the delay by unforeseen image quality problems which resulted in a requirement to change the specification of the camera's imaging pipeline. Luckily things seem to be back on track now with alpha testing of the final design having started in November. Click through for a link to the official announcement.
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.
Sigma has made available firmware v1.05 for its SD14 DSLR. The big news with this latest release is the addition of ISO 50 to the camera's extended mode. This comes with the warning of reduced 'headroom' - read dynamic range - and suggestions on how to cope with this side-effect. The update also implements fixes aimed at improving stability of the camera and is available now from Sigma's site, link after the jump.
Sigma has released version 1.04 firmware for its SD14 DSLR. The update corrects an intermittent camera freeze, improves video output and fixes the remaining-shot counter.

The update is available now via the sigma-sd14.com site - link after the click.
Sigma has today released version 1.03 firmware for the SD14 digital SLR. This new firmware contains two fixes; Corrects the intermittent camera freeze while CF CARD BUSY LIGHT is on during continuous shooting. Corrects the remaining battery power display on the top LCD panel. Firmware can be user updated and higher version numbers contain all the fixes of previous versions. This new firmware can be downloaded from the sigma-sd14.com website (link after the jump).
Sigma has released V.1.01 firmware for its newly launched SD14 digital SLR. The changes implemented include various improvements to the flash system and the ability to enter sensor cleaning mode without the use of an AC adaptor as well as polishing up the playback quality.

Sigma has announced that the latest version of its Pro Photo RAW development software which is bundled with its latest SD-14 DSLR will be available to users of SD9 & SD10 cameras from early April 2007. Sigma says this latest release has an improved image-processing algorithm and that v3.0 for PC and v2.2 for Macintosh will be available via the Sigma website.
PMA 2007: Another Sigma product revealed at Photokina but confirmed today is the DP1 compact camera with an APS size sensor. The DP1 features the same Foveon 14M X3 sensor (2652 x 1768 x 3 layers) as the SD14 and a fixed 16.6 mm F4.0 lens (providing a 28 mm equiv. FOV). Significant changes since the development announcement back in September include a hot-shoe and external viewfinder.
PMA 2007: Although revealed at Photokina six months ago Sigma has today officially announced the 18 - 200 mm F3.5 - F6.3 DC OS lens. This compact lens offers a big 11x zoom range in combination with Sigma's own Optical Stabilizer. It features aspherical and low dispersion elements as well as multi-layer coating to reduce flare and ghosting. On the downside it is slow (F6.3) at telephoto (you can't have everything at this price). On a digital SLR with a 1.5x FOV multiplier this lens provides an equivalent field of view of 27-300 mm on a 35 mm camera.
PMA 2007: Sigma has today announced one massive beast of a lens; the APO 200 - 500 mm F2.8 EX DG. This lens is stated by Sigma as being the worlds first Ultra-Telephoto Zoom Lens that offers an impressively fast F2.8 maximum aperture through its range. The lens also features and LCD panel with a readout of focal length and subject distance. If 500 mm isn't enough reach a dedicated 2x Tele Converter is supplied with the lens as standard and changes it into a 400 - 1000 mm F5.6. Combine that with a typical APS-size 1.5x FOV crop on a digital SLR and you've got either 300 - 750 mm F2.8 or a 600 - 1500 mm F5.6 (better have a good tripod). No news on price, availability or weight yet.
Sigma's website in Japan has today published a brief announcement stating that the new SD14 digital SLR will finally start shipping on March the 6th. The SD14 was originally announced at Photokina in August 2006 and Sigma had originally intended to ship in November or December of last year. Well, the wait is now over, and eager Foveon fans will be able to get their mitts on the new model within a few weeks.
Sigma has today announced the postponement of the SD14 digital SLR which was initially due to ship in November, this was later put back to December. The new date of availability for the SD14 is March 2007, this due to "one issue that occurred occasionally and only under certain circumstances." Sigma go on to say that, "Initially, we felt that this could be solved with a programming or processing solution. However, after careful investigation and many attempts at a solution, we have come to the conclusion that we need to make a hardware change to fix this issue completely."
Photokina 2006: Sigma has announced another digital-only lens, the new 18-200 mm F3.5-6.3 DC OS lens. This compact lens offers a big 11x zoom range in combination with Sigma's own Optical Stabilizer. Just like the 18-50 mm DC lens this one features aspherical and low dispersion elements as well as multi-layer coating to reduce flare and ghosting. On the downside it is slow (F6.3) at telephoto (you can't have everything at this price). On a digital SLR with a 1.5x FOV multiplier this lens provides an equivalent field of view of 27-300 mm on a 35 mm camera.
Photokina 2006: Sigma has announced the interesting 18-50 mm F2.8 EX DC Macro lens. Like all other DC lenses this is designed specifically for digital SLR's with APS sized sensors. It offers a maximum aperture of F2.8 throughout the zoom range and a minimum focus distance of 20 cm (7.9 in). In addition the lens features aspherical and low dispersion elements. This should be an interesting alternative to the often poor kit lenses bundled with sub-$1000 digital SLRs. On a digital SLR with a 1.5x FOV multiplier this lens provides an equivalent field of view of 27-75 mm on a 35 mm camera.
Photokina 2006: Sigma has today announced the long awaited successor to the SD10, the new SD14. The SD14 features a Foveon X3 sensor with '14 megapixels', those being delivered over three separate color sensitive layers, in a 2652 x 1769 x 3 configuration. In its optimum native output size (2652 x 1769) the SD14 offers approximately 35% more resolution. The sensor size remains the same meaning a 1.7x field-of-view crop. Headline improvements include in-camera JPEG, a larger, brighter viewfinder, a larger 2.5" LCD monitor, Lithium-Ion battery, improved auto focus and continuous shooting and a built-in flash.
Photokina 2006: Sigma has today announced the interesting, unique DP1 digital camera which features the same Foveon 14M X3 sensor (2652 x 1768 x 3 layers) as the SD14 and a fixed 16.6 mm F4.0 lens (providing a 28 mm equiv. FOV). As a development announcement there isn't a lot more detail than this, a quick look over the body images reveals a large LCD monitor, pop-up flash and the expected range of manual controls.
Pre-Photokina 2006: Through the use of a teaser website Sigma has today revealed the existence and name of their next digital SLR. The SD14 will be announced on 26th September (first day of Photokina) and has a 'Full Color Capture Direct Image Sensor' (read as a new Foveon chip). No other details have been revealed at this point but as always we will follow this evolving story in as much detail as possible.
Sigma has today announced a very interesting sounding lens, the new APO 50-150 mm F2.8 EX DC HSM. This lens promises to be compact (its DC notation means its designed for an APS-C size imaging circle) and fast (an F2.8 maximum aperture) with a good telephoto zoom range, HSM focusing motor and four SLD (Low Dispersion) glass elements to reduce chromatic aberrations. This lens on a 1.5x crop digital SLR (such as the Nikon D80) would provide an equivalent FOV of 75 to 225 mm.
