All of the standardized test results (image quality, vignetting, flare and distortion) along with specs, measurements, standard product images and the owner's manual are now available on the Canon EF 11-24mm f/4L USM Lens review page.
My plan is to have the full 11-24 L lens review completed this week.
B&H has the Canon EF 11-24mm f/4L USM Lens available for preorder.
