New addition to the ultra-wide crop market…

Competition heats up in the ultra-wide angle zoom market with the announcement of Tamron’s new 10-24mm f/3.5-4.5 bringing a competitor into the field from every one of the major manufacturers (Canon, Nikon, Tokina, Sigma and now Tamron). If CA is well controlled and the lens is sharp enough, this could give Canon’s EF-S 10-22 f/3.5-4.5 a run for it’s money, and with 2 more millimeters on the long end would fit well with their L series mid range zooms (either the 24-70 f/2.8L USM or the 24-105 f/4L IS USM). For Nikonians it gives you 2 millimeters more wide angle coverage than the DX Nikkor 12-24mm f/4, with only a third stop penalty in speed at the long end.
