Canon 7D user thinking of switching to Nikon D600, big mistake?

Two different cameras - the 7D a crop body and the D600 full frame. I know that my Canon 50mm 1.8 lens on my 7D is fantastic. Both are excellent cameras. The D600 3 years newer technology - the 7D still one of the best crop bodies around if not the best ever. If you want a full frame camera I see nothing wrong with switching to the D600 and the Nikon 50mm lens as you don't have much investment in Canon lenses. However, I would also consider the Canon 50mm - probably a cheaper alternative for you. A couple of things to consider - according to all reviews the D600 has better high ISO than the 7D but may not be as good at high action photography and you give up the extra reach (the crop factor). Depends what is most important to you. Can't go wrong with either decision.
