This is an update to my earlier post.
I have the pleasure of watching these 2 swallow chicks being fed quite close to our house. With some ninja tactics I managed to get a position which allowed me to witness the feeding ballet between parent and chicks. Problem for me was the pair of younsters were quite far apart, I never knew which one she would pick to deliver the goodies to. Concentrate on the left chick, she would feed the right one. All this flight and feed, happened in the blink of an eye.
Even at 1/4000 of a second on high speed drive, I didn't get all the action, they are just so quick. The images were shot with the Fuji Xt1 and 55-200 mm lens. The best reults came from having the lens set on A/F C (continuous focus) set to focus priority release. That means the camera will only fire when the subjects are in focus. I think the sharpness and IQ from the 55-200 are fantastic, its a great lens. Sadly the family have all taken to the wing, after a few short days they are now zooming about like daft things. Not be too much longer before they make the long trip south to Africa for the winter.
