Member jon595 on mu-43.com posted a great series of kayaker pictures - all shot with the Olympus OM-5 and Panasonic 45-200mm lens.

Apparently, they were dropping off a 20' fall.
While I very much like the feeling of being right there with the kayakers that was accomplished with the telephoto lens, I would also love to see more wider angle shots, including the scale of the drop. Maybe that vantage point was inaccessible? Anyway, these are great.
Here's one of my own, shot from high above the Potomac River at Great Falls, Virginia. I was not able to get closer to them.
