Personally, I will stay with Canon. If the MKIII doesn't meet expectations and comes up short against Nikon's offerings, it just means Nikon has won the battle, not the war. It's always back and forth and it's an expensive past time selling all your depreciated glass and equiptment to switch when in 2-3 years, you may be on your way back.
I think it's sad how people think equiptment make them a good photographer. It helps, in some cases, from a technical standpoint ie. more megapixels but I would say the vast majority of people on this forum are not professional photographers, who think that switching companies and getting the newest tech or upgrading with the current company they shoot with will make them vastly better photographers. I love tech just as much as the next person, but work more on your craft and become a better photographer and what you can do with your skills and talent not what the camera can do for you.
So all of you are switching...buh bye, have fun... In a couple of years, you'll be possibly switching again...
I agree completely, we are long past the point that a body upgrade is going to make a substantial improvement to the quality of your images. It would be too much of a pain to switch to Nikon, plus everything is "backwards" from the way you twist on the lens to the focus ring, to the dials. Honestly if the 5DIII didn't have improved video I probably wouldn't get it, but considering it's the 2nd generation of something great I'm sure it'll suit my needs.
If people want a positive response to their declaration of switching to Nikon they should go to Nikon Rumors.
