You seem to be in a good mood today 
Well, for one after nearly freezing my a** off yesterday I really value this day of staying the sunday inside near the radiator and procrastinating on CR :-) ...
+1 for very low level shots BUT EUR 2000 for the 6D ... THAT'S GOTTA HURT!
... and I recently realized (again) that my 60d is a good camera with an appropriate price, currently I'm very happy with carrying around the 17-40L €1300 combination instead of a €5000 5d3+24-70L2, at least for my amateur recreation shots.
I know that I'll have to buy a ff camera for event shooting, but I've got some time left to practice with the 60d until the 6d drops further in price - just like you imho €2000 is a lot of money for any dslr and esp. for the 6d, though other people seem to think that it's a steal for a Canon ff and people should be happy it's even got working buttons :-o
I wonder which uses more energy and which contributes more heat and electrical noise inside the camera?
Wifi will eat more energy hands down than a dimmed down lcd - but I'd like to know how long exactly you can do lv with a smartphone, did any 6d owner do any benchmarks yet?
