With two 10-20mm lenses already within the Sigma stable, how exactly does this superwide offering fit into the line-up?
This lens doesn't really sparkle in the same way as Sigma's 10-20mm f/3.5. If the last 2mm aren't crucial, the fixed-aperture zoom is probably the better bet, but at least the 8-16mm lens is there if you need it.
