Some young man with his gripped 5D (?) + 24(28)-70L.
He must be a pro because:
(1) The lens hood was done with electric tape or something.
(2) The camera/lens was dangling freely suspended on the camera strap, and no bag in sight.
I believe he took some pictures of me as I was shooting pijuns in flight using 15mm FE on 1D MkIIN. I also think that scene made him nervous.
