portrait of 2 year old

The 70-200/4 seems to work nicely at 200mm (for example this shot), at 70mm I don't get the sharpness I expect. I fear that what I read on the net about the recalibration rate of these lenses is true... :(

But if you get focus right, this is what it looks like

Really nice example of what the 70-200 can do. Nice bokeh, and your choice of 'widescreen' format works really well for that image.
