Some other questions I hope someone can answer for me.If I buy a Canon camera, is it always better to use Canon lens? What if I buy a Nikon lens to fit into Canon DSLR body?

If I buy a Canon camera, is it always better to use Canon lens?
Yes.

What if I buy a Nikon lens to fit into Canon DSLR body?
Yes but you need a mount to convert Nikon F-mount to Canon EF mount. Usually you will lost AF function and auto-exposure function.
