This is my first attempt to grab a bird in flight. Mine was a Sigma 70-300 f4-5.6 with is not a very fast lens. Shutter speed is 1/400 (that speed is not available in the dropdown hence I had to click on 1/350)
Since this bird hovered around for some time I had the chance to take many photos. I must've clicked about 30 photos of this guy and thought this shot was the best of the lot.
