So... I'm still working with my T3i, I've had my eye on getting a 5D mk iii for some time now, but I just can't seem to save up enough to purchase it (seeral expenses have set me back). I've noticed that 6D are now back instock at b&h and are much closer to my price range (will still need to buy a lens for it).
Now I do a lot of different type of work with my T3i. I do greenscreen (got a small studio with proper lighting, I pull decent keys for what it is), work in lots of low light (lighting is generally poor indoors and outdoors where I live), and I sometimes I can do proper commercial work. I've seen the amazing difference in noise reduction of the 6D vs 70D, and the 70D vs the T3i, I can imagine that with ALL-I (correct term?) and say a 50mm 1.8, I should be able to do decent low light with my small 160LED lamp, and even better greenscreen in my small studio.
If your budget limit was 1500.00, would this be the best camera you could afford for the above tasks when upgrading from the T3i/600D?
