Some great shots John, and many thanks to etudiant for your kind words - high praise indeed!
John - the pigeon is a fine shot through glass, you've caught the Waxwing in a great pose and that owl is really evocative.
Stephen Ingraham has written about using the RX10iii to shoot birds in flight here:
He helpfully includes his settings.
Shooting owls in flight at night is way beyond the level of my ambitions right now but I did get my first reasonable shots of a BIF a few days ago - of an Oriental Pratincole on my airport patch. I did better when it was on the ground and typically confiding.
I almost forgot I was also pleased with my BIF shot of a Siberian Crane - something of a mega in HK!
