Sigma Lenses
Sigma just announced two new lenses: A 50-150mm f/2.8 zoom specifically for APS-C size sensors and a 70-200mm f/2.8 zoom for full-frame cameras. The latter appears to be roughly equivalent to the Canon and Nikon offerings, less image stabilization. No word on pricing yet, but for more technical details, check out the press release over at The Digital Photography Review.
