"The final "Should you switch from Canon to Nikon?" posting"
aww cmon guys . I juts moved from Olympus to Canon . LOL .
Just my opinion but I believe very few people will actually switch camera makers, the majority who don't like the 5diii will just hold onto the current camera and see what is offered next. Whether that is a 3d, 5dmiiih, 7dmii there will be a next camera.Maybe.., but there will be people buying into nikon without leaving Canon.
1)Do you have the cash to do it? IF not, you are finished. Others, read on
2)Do you care if the reviews are not out on the new cameras? If you do, you are finished. Others, read on.
3)Is your equipment about to self destroy so quickly that 1 and 2 don't matter? If it is, read on.
4)Do you follow the herd even when it has been spooked? If yes us let us know where it is going. (just curious!)
5)Will the eventual difference in performance in whatever spec you worry about make a substantive and noticeable difference to your performance as a photographer paid or otherwise? If yes, you need to read 2. You are finished.
