BPL Staircase - GoPro

BPL Staircase - GoPro, a photo by andyi on Flickr.

So how good should a fisheye shot be? At least as good as this one.

Here's a shot taken from the same spot, on a different day, using the GoPro HD camera's still photo mode. The GoPro's ultra-wide-angle lens focuses directly on the camera's image sensor, so the image is perfectly sharp from edge to edge.
