Flying Seagull

Flying Seagull: A seagull is flying over river Aare near the Schachen island at Brugg. It is a test shot with my used bought Nikkor 300mm f/2.8 and Nikon TC-20E II teleconverter. The autofocus catched the wing instead of the head why it is not properly focused. Nikon D3, 1/1000 s, F/5.6, 600 mm, ISO 220, Friday, April 27, 2018 08:31:16
