Canon or Nikon?  By far it's the number one question I get asked.  I'm sure most any other photographer gets the same question.

It's an easy answer...it doesn't matter.

There used to be some points of consideration, such as Nikon had better flash technology for years, upper tier Nikon lenses may have less distortion than a comparable Canon lens, Canon camera body technology is better than Nikon's, Canon's have better ergonomics and so on.

But today I think the differences are so small and esoteric that it's meaningless.  Get the camera that feels better to you.  If you like the word Canon better than the word Nikon, then get the Canon, if the Nikon fits your budget better than the comparable Canon then get the Nikon.  

You get the idea.

So once you decide on Canon or Nikon, then you have choose which camera body to get.  This is a whole 'nother ballgame.  I can't help you here.

However there is this fella, Thom Hogan, that has a website and he reviews pretty much every camera out there, as long as it's a Nikon.  It's very a helpful site but not organized all that well.  You have to dig around a bit to figure it out.  Thom is a protege of Galen Rowell, which is a pretty darn good pedigree.

There is another guy that does a more "common man's" reviews.  Some do not trust his views but I find them to be worth reading anyway.  This web site is easier to navigate as well.

If I find a similar resources for Canon camera reviews, I'll pass that along as well.
