Ok, I stopped watching after 2 minutes.
@sepiareverb - I find walls quite difficult w/ RF. A brick wall: which grout to line up in the patch (careful you aren't a couple bricks over and everything looks right)? Perfectly smooth wall, well, we need something with contrast to line up in the patch..
I was at a family wedding on Saturday and the RF was quite a challenge with the little ones on the dance floor (especially my 2yr old niece dancing in circles!). Would have been nice to have the 5D, but quite glad to have the RF for a number of other reasons (including not being "that guy" with the same camera as the paid photog!).
I think a manually focused 5D (with good focusing screen and nice bright primes) equals or beats the RF in most cases (including low light).
Not too sure about AF though, I rarely use it, so can't offer much of an opinion.
Note: keep that VF and patch window nice and clean! Nothing like a clear patch.
