This photo illustrates the reason I bought a ZS40 as a carry-always camera.
These swans were just unrecognizable white specks in the distance and the
only camera I had with me was the ZS40. Shot at its full 720mm EFL and
cropped to almost 100% view and while not a great shot, image quality is decent.

Photographed along the Rideau Canal Waterway at Smiths Falls, Ontario, Canada.
