Overview of Tamron SP 15-30mm f/2.8 Di VC USD
This comparison turns out to be one of the very best yet for showing the awful focus shift in the Nikon 14-24mm f/2.8G.
It also makes a good demonstration of how image stabilization can damage image sharpness. This comparison won’t answer all the optical questions (some reshooting needed), but I deem it more interesting and thought provoking than most comparisons!
