Budget is the first step you need to decide.
1 point and shot (can't change lense)
2 DSRL (DX or FX)
3 mirroless (can change lense)
Camera body is not that expensive. Lenses is going to kill you.
Personally I like Nikon better than Canon.
Try D7000 (DX) or D800 (FX).
(D600 is a FX camera but the spec is not higher than D7000)
Once you decide the body. Then you can start shop for the lenses.
