Upload & Sell: Off
I will be waiting, price is, IMHO, very high, just like all recent canon releases.
I don't have a canon camera right now, using a D3s at the moment, but I kept most of my canon lenses, as I just couldn't sell them.
I really, really want to use my canon lenses as I miss them very much, but I want a FF camera with good AF and it's just very hard to justify the purchase of a 5DMIII right now, specially considering what the opposition is offering, at a lower price (at least in Europe).
I see little reasons to buy a 5DMIII instead of a D800, except for the fact that the D800 does not have an EF mount...
So I will be waiting for the price to come down, even though it's a pain to see those fine L lenses kept away, unused...
