The Sigma 18-50 f/2.8 EX DC Lens

Shuttertalk has a review of the the Sigma 18-50 f/2.8 EX DC Lens

Sigma recently expanded its commitment to the “DC” line of lenses for digital cameras, introducing three new lenses designed for digital SLRs with APS-C size sensors. APS-C sensors give a narrower field of view than full-size 35mm sensors, resulting in what some refer to as a 1.5x or 1.6x “magnification factor." The new lenses, which will include a 10-20mm f/4-5.6, an 18-200mm f/3.5-6.3 and a 30mm f/1.4 prime, complement the current selection which includes an 18-50mm f/2.8, 18-50mm f/3.5-5.6, an 18-125mm f/3.5-5.6, and a 55-200mm f/4-5.6 lenses.

"In our opinion, the Sigma 18-50 f/2.8 EX DC is one of the best consumer/prosumer wide-angle zoom lenses we’ve used. While the price is a little higher than some lenses in this category, the constant – and usable! – f/2.8 aperture makes the lens a real winner in terms of value. While it would have been nice to have a HSM motor and a depth of field scale, the missing elements do not detract from its otherwise strong performance. If you are considering a wide-angle “digital lens,” do consider giving the Sigma 18-50mm f/2.8 a try."
