- After my experiences with 3rd party brands it would take a heck of a lot to get my to buy a third party lens. I will probably always buy the same brand lenses as the camera.
I would stay with one system.
and after looking at the current Nikon system... I don't see a good reason to go back to Canon at all.
I am not good enough to benefit from any minute changes I might get from switching systems and I also don't care enough about the newer cameras and stuff plus I am pretty impressed with Nikon's current lens lineup
