Man, I gotta get me one of those straps. I never use a strap at all, but I totally want a D800 strap to stick on my D3100.
The dude does look weirdly furtive, doesn't he? Do we all look like that when we're taking a picture? I gotta say my first reaction was 'ugh, photograph of a photographer, not again' but I think I see a little bit of what you saw here.
Who's stealing a moment from whom here, eh? Was there a third photographer taking a picture of both of you?
