Digital photography

That's your first world problem right there!
Just send me the MkIII, and keed using the 7D (as it's lighter), or give that one away as well (to wblati), and think about throwing in a nice zoom for good measure!

You're right it is really a first world problem, I might want to sell the 70-200 or ideally swap for a 24-105.

If anyone is interested, I would be looking for

£350 for 70-200

and I'll only sell one body, but, would be looking for

£550 for the 7d
£600 for the mkIII
