Canon EF 400mm f/2.8L IS II USM

The long wait was definitely worth it. I just got the lens and it matches my expectations based on Canon's MTF curves. Each of my Canon bodies (5DMkII & 7D) require microfocus adjustment to extract full sharpness down to f/2.8. I am stunned by how sharp this lens is with either of Canon's latest teleconverters (III). While the price should demand it, I'm feeling the fact that I now have a sharp 800mm lens is a bonus. Great job, Canon. Price, OUCH! Love the smaller sized case with its slots for the two teleconverters.
