Just a couple examples... The first one of my dumbo (I have the picture as an 8x10 portrait framed on my wall!) shows how it pulls color, and despite his long fins, it made the movement more soft, almost feathery.
Second one is of a baby fish from one of my most successful spawns. It pulled the scales, the face, everything into account from the "bird's eye view" point.
Lastly is a little female from the same spawn, it went passed curved glass (jar), and still captured the little fishy. The lense itself was probably a centimeter and a half away from the glass. Which is awesome just for close ups. Literally, close up
A lot of the powershots are amazing, even the mock Rebels (look like smaller versions without interchangeable lenses) give you the professional look and feel, while maintaining a compact form.
