Very sharp from wide-open even when using a 1.4X extender (Version III). Focus is very fast and the lens generally has no problem tracking fast moving objects (I mostly use it for surfing photography). Image stabilisation is generally very good and I have managed to use it handheld on 1DMkIV for short periods using a good stance.
It's a big and heavy lens, so you need steady support. It's worth investing in a gimbal mount to get the best from the lens. I use a Wimberley sidekick.
There is very little to criticise for this lens except the rather steep price and weight, which comes with the territory of the pro-super-tele.
