I'm getting ready to sell or trade my 40D and it's grip, and I'm at a loss of whether I should go to the 1D Mark II N or go all out and get the 1D Mark III. I really like the convince of the toggle and set button, but this will also be my first 1D series camera. I'm currently shooting with the 40D as my back up, and the 7D as my primary. I do a lot sports photography, but I also do a lot of photojournalism work too. I'm looking at the 1D series because of the speed, but also because of the 1.3x crop to give my lenses a more full frame feel. The ability to back up photos as I shoot is a bonus. Those are some of my thoughts on them, but what are some contrasting ones to go one or the other?
Any help would be greatly appreciated.
Thanks.
