Weekend pics: Chicago Air and Water show

On a poorly-planned trip, I got fewer good pics than last year, but a few decent ones. Mainly, the trip demonstrated the value of high-quality equipment. My full-frame camera with a 300mm lens got much better pics than my new super-zoom Nikon P900. The P900 got a few cool pictures of parachutists from miles away, but the soft lens, camera jitter, and related challenges made it hard to do action shots at high zoom.

This from maybe 1.5mi shows strengths & weaknesses of super-zoom camera
