Hello,
This was taken a few years ago at a re-enactment of a famous battle in Yamanashi, Japan.
It was taken with the Canon 60D and the rokinon 8mm fisheye lens.
The reason that's important is that I was very close to that horse and others at this time while they were moving so it was very dangerous, I could probably almost touch the horse if I extended my arm out.
The event was lots of fun and I got a lot of great photos, and the reason I used the fisheye lens is because of how close it makes the viewer feel to the action.
