Cathy, it really is no contest for the D7200.
I've gone from a D800 to a D7200 and couldn't be happier. All your lens will work fine on the D7200.
The D7200 has more megapixels, 24MP vs 16MP, No Optical Low Pass Filter, much better high ISO handling, released 4 years later with better in-camera image processing, much better auto focus, higher resolution display screen etc, etc and the list goes on.
If you decide on the D7200 make sure you get it from an authorised Australian dealer as you will get 2 years Nikon warranty PLUS $50.00 CASH BACK if you purchase it before August 9, 2017.
Good luck with your deliberations.
PS: Love the NH Honeyater and it would be just that little bit better with the D7200.
