After all the amazing pictures sum1sgrampa posted, I'm kind of humbled if not ashamed to show this one but I'm playing with my new toys, OM-1 II and Leica 100-400 II so I tried to catch one in flight:
What I like about this lens is that you can also use it for landscape. Mont Blanc, i.e. highest mountain in Europe 40 kms away, the first one with 1.4 multiplier, i.e. 560mm.
I could see this spot in my viewfinder while I was tracking these Eastern Amberwings in flight. I never expected I'd be able to get one framed like this. Dumb luck
