Hi all, I'm looking at upgrading from my trusty 40D to some full frame goodness. I was set on the 5D Mark III however the recently released 6D has me a little unsure about which way to go. I mostly do portraiture, event, travel and low light photography with a little but of landscape thrown in. Obviously the 5D Mark III is great all round. I like the smaller size of the 6D which would be better for travel but am not too sure about the autofocus system. Lenses I use are the 24-70mm f2.8 L, 50mm f1.4. If anyone has any advice or hands on comparisons that would be great. Thanks!
