Sharpness test 70mm

Just some sharpness testing of the Canon EF 70-300mm IS USM, shooting at 70mm.

I'm quite surprised by the sharpness at f/4, I would have thought it would be a bit softer there... on the other hand, at f/20 and over, it gets quite horrible - lucky I don't shoot very often at those apertures. :)
