Of course, milandro is all too right in what he says. Coming from someone with a whole cupboard full of Fuji X gear, there is no doubt that many of us, and to some extent that includes me, are the victims of good advertising.
 
Seeing the high quality images produced by experts and hawked around by the marketing department lets many to believe that they could produce images of an equal standard if only they owned this particular widget.
 
Deep down of course we all know that it is the nut behind the camera that makes the difference, but it is tempting to think otherwise. 
 
While I own the X-T1 as well as the X-T2, I still love to use the first Fuji camera that I bought, the X-E2. I just love the way it handles and the resulting images are still simply amazing.

There is no way of escaping the laws of physics. The smaller sensor of the Fuji X system requires the aperture to be approx one stop faster than the equivalent FF application for the bokeh to look the same. As Pierre points out, the Canon 70-200 f/4.0 would create an image that more resembles the Fuji 50-140.
 
Apart from the bokeh comparison though, the Fuji 50-140 is a fantastic lens. Amazingly sharp and a real joy in use. It gives good contrast and in keeping with the Fuji tradition, the colour rendition is superb.

Oh Bliss! Being able to name camera presets finally makes them useful. At my age, I can't remember which number is Portrait or Landscape. Fuji has answered my prayers.

I have bought a tilting adapter to fit an old 17mm Nikon mount lens onto Fuji X cameras. It works remarkably well as a landscape lens setup. It has completely replaced my Nikon 24mm tilt shift lens.
 
Since this application requires a tripod mounted camera in any case, the fact that AF is not available is no problem. Perhaps the only trap to avoid is the rotation of the lens assembly. It really requires some care to ensure that the tilt is in precisely the correct direction.
 
This rig does quite a lot of work for me now. Of course, the usual Scheimpfug rules apply to this just as they do to full frame lenses.

I really like the X-T1 (FW 4.3) for tripod mounted work, but simply love the X-E2 (FW 4.0) for handheld use. It just suits me perfectly.

Being a landscape photographer from way back when..., I never expected the Fuji system to be anything other than a good casual rig for photography. When I bought my X-E2 though, I was simply bown away by the quality of the resulting images. I am now in the process of divesting myself from a couple of D800E's and am concentrating on using Fuji. For landscape worl and even for some wildlife, it is simply amazing!

Could this be a monochome only version?

The Fuji sensor seems to be ideally suited to rendering the fine texture of the plumage. Bring on the 100-400mm - PLEASE SOON!

I have just recently taken delivery of my 50-140mm. Sure it is big for a Fuji lens and the tripod foot sticks out a lot. However it is easy to remove the foot, so this is not much of a problem.
 
Last night I took it out to shoot the nearby lighthouse after dark. 30minutes after sunset, it still managed to be sharp enough that I can distinguish the fence wire 2km distant! The optical performance of this lens is simply astounding. My Nikon 70-200mm would be hard pressed to match this.

I have both the X-T1 and the X-E2. The viewfinder of the X-T1 is just to die for and it is fabulous camera, but it is the X-E2 that I love. It is the camera that finds its way into my bag before the other.
The rangefinder style suits me better than the SLR one.
On this basis, my preference would certainly be the X-Pro2, given the hypothetical specifications.

I have settled on a Lee type setup. The main advantage of this system over screw-on filters is that they are quickly and easily clipped on and off. I am into long exposure landscapes that make it necessary to compose and focus before installing the BigStopper. Light intrusion between the filter and the front element has, much to my surprise, not been a problem.
 
The added advantage using this setup is that I can also use it with my full frame Nikon gear.
 
One adaptor ring for each size of filter thread is all it takes to accommodate all my lenses.

I have taken my 55-200 on a recent trip to the US and Canada with some success. It allowed me to travel by air without having to worry about excess weight and I haven't missed a single shot because of the smaller camera system. For slow moving subjects, this lens paired with and X-T1 worked fine. For birds in flight it would be challenged since the focusing is not the fastest. No doubt, the upcoming FW update for the X-T1 and the planned 100-400 lens should be up to that task quite nicely. 
 
I should mention that the camera and lens performed in -30DegC without a hitch. This same setup will be my backup for a trip to photograph bears in Alaska in next month. I am sure it will perform just as well.
 
I have used this combination for some local Bird-In-Flight work with occasional success. To be honest, it worked better that I expected, but until the really long lens comes along, I am stuck to the D800E and the 500mm prime. The reduction in weight will be very welcome when the new lens finally finds its way into my bag.
