Nipped into the garden as it was so nice and took a few quick shots to get afeel for the new 100-400 lens. Here's one taken of an iris 125/sec f11 @ 400mm iso200 This is the full frame.
Now I have to say I'm not used to using such lenses, but already its obvious that for close work at full reach wide apertures are not too useful and DOF is very shallow even at f11. However also, to say it was at 125/sec it suggests the IS is pretty effective.
