Re: Sorry, but this is not a valid comparison.

I didn't use tripod, I don't even own one. I always shoot handheld. The shutter time should be short enough according to the usual thumb role (around 1/200 and 160 mm FF equivalent FL) and IBIS was on which should give a three stop margin. And AF was on, with small focus point aimed at the edge of the bird feeder. Shouldn't suffer from motion blur unless I have severe tremor and I haven't.
