Why does it need a defense? Its aimed at a certain market segment and is the right product for that segment. It will take fantastic photos in the right hands.
I'd love to have a touch screen on my 5D MK III.
I'd say it doesn't need defending at all - that was my point. But as I said, to read the forums here when it launched there was actually a lot of cynicism. So this post was to try and balance out that with a bit of "right product for right segment realism" but - above and beyond that to share a really positive experience of a very good bit of product design. And moreover, my point on holding off my upgrade to my 5Dmkii was that the experience of the current crop (unintended pun) of consumer grade bodies and of the 6D makes it a tough time to change. I too would love a touch screen on a 5D body.
