I wanted the better AF but im coming to realize that I will either start practicing landscapes or do portraits and I think the AF is sufficient, plus I can get a nice lens with it too, and better tripod. Sigh, decisions, decisions. if you want to spend it all on a camera body or get a body and lens or two.
Esp. reading Dustin's real world review and posts here I came the conclusion that I'll go with better/more non-body gear, I've put the 6d->5d3 difference in a 17-40L, books, large cpl/nd filters and flash accessories like diffusers and a bracket.
The 5d3 is very nice and the af enables shooting my 60d or 6d cannot do, but it's also only a camera after all and for most shooting styles the photog and the lenses make the difference. Plus I've seen how much value a camera body like the 5d looses quckly, so I'm definitely not willing to pay €3000 for a camera unless I would have full amortization with more/better paid contracts.
