Will a nikon lens fit a cannon camera?

I'm getting a cannon. And i was just wandering if i could fit a nikon lens on it?

Yes, BUT you will have to get an adapter.

Now pay attention to this part of the link given above to an adapter:"First, remember you are playing in God's domain. This isn't supposed to work at all. You can and may destroy your camera, lens, or both. "

If you have a Nikon system now, switching to a Canon (not the military weapon a cannon) is not a good idea if for no other reason, the cost involved, replacing all the lenses and learning a new metering system. The same goes the other way. There must be a compelling reason to switch camera systems from say Canon to Nikon.

In any case, using adapters from one lens to another reduces a super fast auto-focus lens to a manual focus lens that may or may not use the light meter in the camera.
