I recently analyzed around 6000 shots taken over 10 weeks at South America with the DX lenses I previously had (10-24, 35 and 55-200). The 35mm equivalent focal length usage as follows:
15mm: 33% (almost 2000 shots!) 40mm: 13% (36mm rounded to 40) 50mm: 13% 80mm: 10% 300mm: 9% (majority of these taken at Galapagos Islands)
As an amateur I shoot mainly landscape, travel, candid portraits, astro and street. No birds, no sport (as mentioned in a previous post). I have so far obtained D750 along with 35mm, 50mm, 85mm f1.8 primes which seems to support my usage behavior however I'm yet to decide on the following:
> 20mm f1.8: hopefully this prime will fit in nicely although not as wide as 15mm. > 14-24mm f2.8 vs 16-35mm f/4: which wide zoom do you think I will benefit the most from? I have been shooting at the edges (15mm & 36mm) mostly based on usage data. 16-35mm would have shareable 77mm filters with 20mm (Hoya: CPL, ND 3-stop and ND 9-stop). However, if I have 20mm and 35mm primes already I am not sure if 14-24mm would be a better option for me? > 70-200mm f4 + 1.4TC III vs 300m f4 PF: I didn't have to use 300mm too much except at Galapagos Islands. I'm however going to Africa next year and wondering how 70-200mm f4 at 280mm (with TC) compares to the 300mm f4 PF? I guess 70-200mm f4 might be better all around lens still.
The F4 line if Nikkors is just that okay, at best. Frankly I don't rate them as being any better than the consumer 3.5-5.6 type zooms for sharpness. What they do offer is a fixed aperture and better flare resistance. Are they really worth significantly more than the variable aperture zooms? Hard to say, my experience says no for the most part.
Yes I'm sure the 14-24mm is wonderful and sharp. I didn't opt for it for the same reason I finally sold the 24-70mm F2.8. Too big and bulky. Of course the 16-35mm isn't smaller either, but it is much lighter.
Also, depending on how long your trip is, renting might be a better/cheaper option, especially if it's a lens you'll rarely use.
PB_PM I am glad to hear I am not the only one who hates the weight. It is the main reason I pack my 14mm Samyang instead of the 14-24 now and more primes as opposed to the 24-70. Or sometimes give up all together and just use my Leica....

With my job I get special treatment from some of the shops as well and even get loner lenses free for certain events. For example, I will be covering the Chusok Korean Thanksgiving festival next week and I get to try out the new 24-70mm VR, which came to Korea on the 15th! Looking forward to that. The 200mm-500mm is here already as well, but can't try it out as it sealed, and no promos on the lens are available yet. You can buy it outright though if you want.
I bet the 2009 16-35mm F4 will be refreshed in 2016 because 7 years seems to be the magic number for Nikkor pro lenses to be updated. I suspect 2016 will be a big year for pro zoom glass to get updated.
