I've very recently switched from a Nikon D7000 to an X-T1 and much prefer the Fuji system for my type of photography, essentially landscapes. I had considered full frame Nikon before opting for the Fuji X series. I'm very happy with my choice:
1. The Fuji build quality is far superior, the camera and lenses are made in Japan from metal not In Thailand using plastic camera bodies and lens barrels.
2. Image quality is far better for less money. Fuji are probably the no.1 top end lens manufacturer in the world.
3. The cameras are fitted with dials for ISO, shutter speed etc, just like real cameras!
4. Much smaller, neater and portable, really important to me.
I could go on but I really like the Fuji cameras with their retro style. I think Nikon are very good though and for action, macro and more specialised photography they are unsurpassed with their range of lenses. It's personal preference if course that should ultimately make up your mind as almost all cameras are pretty good these days.
I'm sure you're right Adam, the D750 would be a great camera as is, to be fair, the D7000. I was entirely happy with mine but the X-T1 just suits me better. They're all tools and they're almost all exclusively good so @Samhi, go and handle a few other cameras but you've certainly got a pretty good one to start with!Tim I love Fuji and I'm desperately awaiting the arrival of my X100T, but to say the "build quality is far superior" and "image quality is far better" just simply isn't true. That might have been the case for your D7000, but it isn't when compared to the D750.
I've owned and used both extensively.
I'm in the same boat. I love the Fuji and if I had the money I would keep it. For me, currently my main interest is small bird photography in the garden, (i'm home all day and this little hobby keeps me sane) I have had and sold the Fuji 50-230 & 55-200mm lenses as they were too short for me to catch the birds.
I have tried manual focus and longer legacy lenses (current 300mm f4) but they are too heavy for my disabilities, I need lenses with AF & VR. I had hoped to buy the super tele which was to be released this winter but it's now been put back twelve months. So I am in the current position where I have a camera which isn't suitable for my needs, so I have put it up for sale. When sold, I will buy the D750 just for home use as there is more longer lenses available in Nikon mount. I will use the XF when going out.
When money allows I will buy the Fuji again, but for the next twelve months or so I will change to Nikon if the Fuji sells.

My photography has changed this year. My main interest is the wildlife in our garden, we have a bit as we back onto woodland, plus I'm home allday. The camera & lens would be set up on a tripod and wouldnt need moving around, so the weight is not such an issue as the camera would be just used at home. It would be too heavy to lug around due to my disabilities.Will you not hit the heavy lens problem with the D750 as well though? Being full frame you'll need a 400mm lens to give you longer reach than 230mm on the aps-c Fuji gives you.
I haven't looked at the EM1, but when I was looking to change earlier in the year I found the EM5 to be too small for me and I wasn't fussy on the UI of the camera. Also, i'm not going to buy a camera on the waiting of a new lens, this is why I'm changing from Fuji. I will have a look at the EM1 and the Panny or Oly 75/100 - 300mm lens, to see what their like.Wouldn't you be better off with something like an E-M1 and the forthcoming 300mm f/4 plus the optional 1.4TC?
Much lighter and long reach![]()

If Fuji hadn't delayed the super tele, we wouldn't been having these discussions, I love the camera but I'm not getting on with manual lenses for it which I need to use for the photography I'm currently doing, thats due to me and my disabilities.
As mentioned in previous post, if I had the money I would keep the Fuji and buy the Nikon. I will come back to Fuji,(providing I sell it), in the near future as a light going out kit. For the time being I will use the XF1.


OK fair enough Simon.
Just to counter a couple of you points though.
The E-M1 is just that bit larger than the E-M5 and in particular the button and switches are more suited to people with larger digits.
Not only that, if you enable 'Super control panel' in you settings for both the E-M1 and E-M5 things become much easier to work with from the UI point of view, have a look here http://www.damianmcgillicuddy.com/olympus-super-control-panel-super/
Regarding long reach glass, thinking more of your keenness to avoid anything too heavy and cumbersome. As you have identified (and Allan mentioned) there is the Oly 75-300 and Lumix 100-300
Grab shot with the E-M1 and 75-300....
Or there are currently other excellent 4/3rds options available with full aperture and autofocus control available by the MMF-3 adapter.
Like the 50-200 SWD plus a x1.4TC (140-560mm FL in 35 mm FOV terms) or a 2xTC (200-800mm FL in 35 mm FOV terms).
Example with 50-200 and x2TC
That's before we start looking at even more excotic Olympus 4/3rds SHG glass like the 90-250 f/2.8 or 300 f/2.8.
But then again the ones that have already been mentioned should keep you happy until the m4/3rds 300 prime is released next year.
