Well, my title is probably enough to send everyone running for the hills, but here goes - the advice I have received at GetDPI has always been helpful, so I save you folks for my thorniest decisions.
I have two main digital camera systems - My Nikon (now a D700 and mostly older vintage but superb glass) and my Fuji (XT-1/XP1 combo and mostly primes except for the 18-55 kit).
When I travel abroad, it is just Fuji now - mostly for ease,compact nature and less intrusive. The reason I mention this is that all of this frustration started with an upcoming trip to visit my daughter in Morocco and a last minute decision to forgo the Fuji 18-135. Just could not convince myself it was worth the investment and now I have cash to invest in camera gear and, well, you know how this goes.
I moved to the SW a few years ago and more recently we have been taking lots of short trips to places that used to require huge 3 week endeavors when I lived in NYC. A nice problem to have. So with this extra 1K available I have the opportunity to trade in the D700 and move to a D750 or a D810. The "main" use will be landscape, but I own the older 84mm f/1.4 and do enjoy portrait work. Probably the only thing I will not use the new camera for is sports (still have my D2X for that).
I have the computing power and storage for the bigger D810 files, and while the most practical approach would be to go to the D750 and use what I have left to upgrade my 17-35 (have never loved it's performance on the D700), I keep coming back to the 36MP on the D810.
So any input would be greatly appreciated, I tend to keep my gear for the long haul so the cost differential between the two does not bother me much. Part of me is annoyed with Nikon for screwing up my decision tree by introducing the D750, but oh well.
As an aside - would also appreciate any advice on the upgrade for the old 17-35, not interested in the 12-24 for various reasons, seriously considering the 16-35 vs a great prime.
Thanks, as always,
