I'm reviving this thread from a year ago. Finally, after a zillion posts, decided to go with a D7500/16-80 for travel. Had considered all kinds of options - a 28-300, 24-120 for my D700, a DF and primes, etc. I'm 72, still hike, but I can no longer carry the backpack full of bodies and lenses. The 7500/16-80 is about as compact as I can go with good (for me) IQ. Liked the D7200 body a little better, particularly the strap loops, but the auto AF fine tune was the decider. Will wait for "Black Friday" to see if I can catch a deal on the combo. Already planning a Guatemala highlands trek for summer 2018. Might as well go out in style!
