Canon 5D Mk II
Sigma 8mm fisheye
Nodal Ninja 5
I shot 2 more from the ground in various places, but each one had a blurred image, which is strange, because that's never happened to me before, and I've been shooting for over 4 years.
I think I bumped the tripod with my foot (it was 1/200th sec, so it shouldn't have blurred from regular use).
Oh well, just remember to relax before shooting, don't rush yourself I guess :)
