Very clean for handheld with a 400....impressed!!!!
I'm having a tough time, I'm shooting with lumix GF-1 (no image stab) and an old canon FD 200mm 3.5 prime. It works out to a 400mm with adapter, but with no image stab...so I have to keep my fstop at 3.5 to keep enough light with faster shutter speed, which gives super shallow DOF.... the problem is its manual focus too, so tight DOF +manual focus = quite the challenge!!! It's making me a better photographer though, so that's good.
Great cap on that female rufous, they are so pretty.
