I stumbled across this thread while beating my head against the wall on "what lens to take?" There is a Charro Days fiesta here in South, Texas this coming Saturday, 2/25/17; we are having some kind of record winter heat wave (in the 90's F), blazing sun, and dust. I'll be hiking about three miles - didn't want to carry a bag of lens, and really didn't want to be changing them. Camera is D700. I do a combo of fine art/ethnographic documentation. So, based on what I've read here, just ordered this lens from Lens Rentals. I'll be posting images next week.
The other alternative would have been primes (of which I have ubiquitous bag full) or an old 28-105 and an even older 80-200.
