I feel you on the Canon front. Have always shot & loved Canon, but they just seem so... lazy! INNOVATE, DAMMIT! And their support, at least in my location, has never been great. Our local sales rep is lazy and rude.
I really love what Sony is doing but I don't like their UI... I guess that's just me being too lazy to learn a new brand properly. Sigh. I'll continue rocking my 5D III until something new inspires me!
Great roundup! Loving this series!
