This may not be for everyone, but they start on Friday and I'm going, so I can guarantee at least one person will be posting in here.
I was so upset about not getting any swimming tickets I went out and bought a 5D MkIII and a 70-200 2.8 L II lens, so my future posts will be using that.
But before the excitement starts I thought you might like these pictures of the London Aquatic Centre taken with my old 400D.

(I subsequently managed to get some swimming tickets so am now effectively bankrupt)
Boxing, volleyball, basketball, tae kwon do, football, water polo, swimming and athletics to follow.
