Just posted! Our new lens review of Canon's top-end fast telezoom, the EF 70-200mm F2.8 L IS USM. This is Part Two in our planned tetralogy of reviews featuring 70-200mm F2.8 lenses tested on both APS-C and 35mm full frame cameras (coming soon! 'The Return of the Tamron' and 'The Sigma Menace'). In our last review we found the Nikon 70-200mm F2.8 VR performing superbly on DX but struggling on the 35mm full-frame FX format, so how does Canon's equivalent stand up to our exacting tests?
