BUT... the one thing that trumps the D800 is the superior video mode in the 5DIII - Headphone jack, volume control etc. Things the Nikon doesnt. And to be fair, everything else is pretty close to each other, with 36MP and video the only two main differneces.
To be honest, am not really fussed about video, am just looking for something that takes really high quality professional grade still shots.
Have had my 500D for over 2 years now and have used the video function on it maybe once.
I still think having 41 Crosstype AF points over 19 is still better - and therefore I will get the Canon based on that. But otherwise, its all just personal choice when I look at both cameras.
Very true, the 5D Mk III's superior focusing ability is a very tempting plus for this camera, however I still like the detail and sharp images of the D800. I thought that Kai's latest comparison video on digital rev putting the two cameras head to head would help me make my mind up, but I'm still undecided.
