When I got my first DSLR (a Nikon D40) I got a Nikon primarily because my father always used Nikon so of course I had to keep the tradition alive. BTW, I still have his old Nikon EM and it works flawless even to this day! There was even a time I had a Nikon D90, a Nikon D80 & a variety of lenses/strobes. But then I decided recently to switch to Canon (blasphemy I know) for several reasons.
1- My wife is a Canon shooter
2- Nikon has an odd lens buy in issue. (middle grade glass is usually AF not AF-S so it's loud and slow)
3- Recently Nikon announced they would NOT be selling parts to 3rd party camera repair shops. I'd be the first to admit that I'd prolly take my camera to the manufacturer over a 3rd party anyway. But I feel that it's a monopolizing move.
4- Pro support is a lot harder to qualify for than Canon's CPS.
...believe me the things I hate/love about Nikon/Canon warrant their own posts! So I gave my self some parameters in this process of deciding whether to switch to Canon or not...
1- I would seriously research this decision as though I didn't have any equipment.
2- I know a heck of a lot more now about photography, then I did when I got my first DSLR
3- I would look at more than just specs and prices
4- I would actually use my knowledge & experience of both platforms and use that to base my decision on.
