You are giving up a lot with that move. I would suggest using the Nikon 18-200 VR II lens. It is much lighter than that monster lens and you will have many more options retaining your current Nikon D7100.
I second the motion re Nikon 18-200 VR lens. It is my walk around lens. Have used it for over 2 yrs. with zero problems! Enjoy!
