my hit rate is single digit percentages for swallows in flight with a long lens. I was out this afternoon and could not get within 50 feet of a sparrow in a thicket, but my shots of ducks on water are great.
Choose the camera and gear for what you shoot.
True...but hit rate on swallows in flight with a long lens is pro single digits for almost all of us...dem li‘l suckas be quick.
