Nikon is a strong company and will certainly have a future, but I don't see a future for Nikon with me. And I say that as a long term Nikon user and former fanboi who has convinced many folks to get into the gold ringed ecosystem in the past.
The reasons are manyfold. To start with, ever since I have added a medium format kit to my arsenal, I rarely use the D800 for the highest quality work. There are many here who can fill an encyclopedia with numbers and charts to argue how the Nikon is actually better, but for my use, it doesn't compare. Not even close.
I have been "tolerating" Nikon color for a while now. My first DSLR was a D70s, which had a beautiful Pop to its colors. That was somehow lost in the D90, D300s and D800 I have used since then. I was so resigned to getting dead, unimpressive colors out of the camera and spending time in post fixing them up that I stopped caring about it. That was until I got myself a Fuji x e1. After setting up my own profiles for it, I see beautiful color from its files which would take a lot more work on the Nikons to match. I got the MF system primarily for its color rendering and now I have a supporting system that has similar priorities. The Nikon system sadly, is at the back of the line.
The whole internet and their grandma are waxing lyrical about the Sony CMOS sensors, so let me be the trend breaker and say, I am not a fan of the "Sony look" anymore. It is too clinical, too plasticky, too perfect for me. Same goes for my Nikkors. Fine texture just does not render the way I want it to be. Again, I see the MF kit and the Fuji (which might have that Sony sensor, but their own CFA makes the difference) doing it better, more naturally. I was thunderstruck by the 36MP claim of the D800 and loved it until I started working with MF. Lots of pixels is great, but lots of pixels used correctly is a different matter altogether. Again with the Fuji, I see 16, very high quality pixels in the files. Still not enough to make big prints like I do with the Nikon, but some day soon they will have a higher MP x-trans sensor and i will be waiting.
But most importantly for me, the difference in shooting experience is what matters. I love the shooting experience of the MF kit. It is very different from anything else and I have no problem carrying all that up any remote location, as I know exactly what I want to shoot with it. The Nikon kit, I used to find a chore to carry around. I still did it because there are many things an MF camera is not ideal for or is too much camera, but I found myself enjoying it less and less. It's too bulky to be used as a versatile solution and what it is supposed to do best (high quality, planned shots), my MF kit is better suited for.
It finally came to the point where I was just shooting pictures so that I can console myself that I shot something. That was when I decided to get myself the Fuji. It was a gamble for not so much money, but boy, it paid off. We went hiking for fall images the other day and for the first time in a long time, I found myself enjoying moving around with a smaller format camera and shooting. I loved how there are real dials for every setting rather than button presses and control wheels. It was something akin to what I used to feel when I used to walk around with my first proper camera, a Vivitar SLR with a lowly 28-70 lens.
I have all but decided that when Fuji comes up with a higher MP XE body, I will get rid of all the Nikon get and move all in into Fuji as my smaller system. Two bodies and 4 lenses can still be fitted into a side bag and I will actually enjoy using them.
There are lots of people out there for whom the Nikon offerings work great. Neither smaller formats, nor MF will satisfy their needs. I am not one of them. Not anymore
