I can never decide if I love or hate filming myself with a fisheye, but as for everyone else, they're sick. Like this!
Steve W got himself a fisheye for his t3i! Most likely one of the Samyang 8mm that everyone (including myself) has, but they're fantastic lenses for the price. You can see that by the quality here - and some really flowy tricks going down that are even higher quality than the lens. Such a nice mellow vibe too.
