Camera and lens news from Sigma

New details released about Sigma DP1 compact, plus two new SLR lenses

Sigma has officially announced more details of its forthcoming and much-anticipated Foveon X3-equipped compact camera.

The DP1 features a 14-megapixel Foveon X3 direct image sensor (2652 × 1768 × 3 layers) as used in the soon-to-be-launched Sigma SD14 digital SLR. This revolutionary image sensor differs from conventional CCD or CMOS sensors becaude it uses three layers of photo sensors embedded in silicon, stacked to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. As well as this advantage, the size of image sensor used in DP1 camera is approximately 10 times larger than those used in an ordinary compact digital camera, which may produce benefits in colour depth and noise reduction.

The DP1 is fitted with a non-zoom 16.6mm f/4 Sigma lens, with a wide angle field of view equivalent to 28mm on a 35mm film camera, and the number-crunching is handled by Sigma’s own True image processing engine. Other features include RAW mode shooting, a 2.5in 230k monitor and flash hot shoe. Measurements are 113.3mm wide x 59.5mm high x 50.3mm deep, with a weight of 240g.

Unfortunately these newly-confirmed details don’t include either a retail price or a firm launch date, but we are assured that it will be very soon.


”’18-200mm F3.5-6.3 DC OS”’

Also new from Sigma are two new digital SLR lenses. First out of the gadget bag is a very desirable 18-200mm F3.5-6.3 DC OS which features Sigma’s own optical image stabilisation system, as well as two Special Low Dispersion glass elements and three aspherical lenses to provide correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting.

The 18-200mm F3.5-6.3 DC OS will be available in Sigma AF, Canon AF and Nikon AF-D fittings, with an RRP of £439.99


”’APO 200-500mm F2.8 EX DG”’

Hot of the press release is news of another and even more remarkable new Sigma lens. The APO 200-500mm F2.8 EX DG Ultra-Telephoto zoom lens is the world’s first to offer a fast maximum aperture of f/2.8 at such a large focal length and zoom range. It’s a gigantic beast of a lens though. Check out the picture below; that’s a Sigma SD14 mounted on the back of it, which is not a small camera. The lens has its own built in LCD display for focal length and range information. No official details have yet been announced about specification, availability or pricing, but you can bet it won’t be cheap.
