Not as sharp as I would have liked but they move rather quickly - just look at the particle storm his wings have thrown up... and this at 1/2500 sec - so I'm happy to have caught him at all!
You've really capture the sense of flight. This has far more going for it than if it were super sharp and 'frozen' mid air. The scattered debris a real bonus.
I struggle to capture these when they on the feeder. they dart about so quickly. This is amazing. Great detail and unusual POV. usually they are captured when landing not taking off!
