400mm, f2.8, ISO 200, 1/1000
That is great, Menace!
I'm amazed at the DOF you got, it's sharp from the tip of his nose almost back to the eyes! I would have thought a 400mm wide-open would give you about an inch!
Thanks Old Shooter, I was standing a bit further back so as not to intimidate the cats (as pe the zoo keepers) hence greater DoF
