Sigma announced the pricing of their groundbreaking 18-35mm f/1.8 DC HSM lens for Nikon DX cameras and I think it’s a pleasant surprise: the lens is currently listed at B&H for $799. For comparison (not really, but still) the Nikkor 18-200mm f/3.5-5.6G ED VR II DX lens costs $846, the 17-55mm f/2.8G ED-IF DX Lens costs $1,399. Shipment is expected to start on July 31, 2013.
