So, after using this camera for a little while now here comes some more thoughts on it.
I'll start by saying that this little camera is in general really awesome. When it comes to handling though, in some ways it falls a bit short compared to my Canon EOS 5D MkIII. The autofocus is good on the X-T1, but it doesn't come close to the 5D MkIII either. As someone who likes to shoot HDR now and then, it comes a bit short so far. When it comes to doing handheld HDR (or on a tripod), the 5D MkIII is much better, since it can shoot up to 7 exposures in auto exposure bracketing mode (I shoot 5) of +/- 3EV (I usually do +/- 2EV) and the X-T1 can only do 3 bracketed shots of maximum +/- 1EV. Not that great. Though I should add that in some cases that might be enough since (at least it feels like) the dynamic range is a little bit better on the X-T1 than the 5D MkIII. I also should add that I haven't really done a real comparison between the cameras or even done much HDR with the X-T1 yet, I simply base this on the feel of the cameras so far.
And also, the camera I will keep on using for landscape/nature for example will still be the 5D MkIII, since it's much more rugged and suited for taking out in that type of environment. Don't get me wrong, the X-T1 feels good and rugged for such a tiny thing, but the feel and handling is important to me and in that way, the much bigger 5D MkIII wins.
Though I have to say that the X-T1 so far delivers really great photos. The Fujifilm X-Trans CMOS II sensor is simply awesome and the XF 35mm f/1.4 that I have with it delivers tack sharp results. The lightness of the camera when walking around a city, doing street photography and the image quality it delivers makes it simply great and that's where I believe the strength of the X-T1 is. I walked around Copenhagen for a whole day with the X-T1 + XF 35mm f/1.4 combination and I didn't even feel it. So as a camera for street and travel photography, it easily beats the 5D MkIII in that way.
When it comes to the coolness factor, I don't really care. I'm not a hipster, so I don't care what the camera looks like, it's not a fashion accessorie and I'm not into the whole retro look that is so trendy right now. The camera strap that comes with the X-T1 one is not great (not the one for the 5D MkIII either by the way) and I will ditch it when I get my new one from Crumpler. I'm in favour of more modern materials for a strap and don't fancy the overpriced leather straps that hipsters seems to love so much. It's just a matter of taste of course. I also might go for one of the grips (not the battery grip, since it kinda takes away the purpose of having a small camera) to add a bit more to hold on to and to feel more secure while handling such a small camera.
Another thing that is a bit on the bad side with the X-T1, is that its fastest shutterspeed is 1/4000 of a second. Fujinon XF prime lenses are ususally really sharp wide open and if you've got lenses like that, why stop down to a smaller aperture? If you want a greater depth of field, that's pretty obvious, but if you want the really shallow DOF on a bright day, shooting on f/1.2, f/1.4 or even on f/2.8 will end in an overexposed picture since the shutterspeed is to slow. An ND-filter can be used, but I'd like to keep that for when I want to take long exposure shots. Fortunately Fujifilm will correct this (together with some other stuff) with new firmware in December, I think. This is already corrected on the new X-T1 Silver Graphite Edition and will be corrected on the regular black version, so hope is there to come.
But as a conclusion so far, the X-T1 is still a really nice camera. I might sound negative, but that's not really the case, I'm just being honest about the few shortcomings that I think it has. Others might think differently. To me it's not a replacement for a DSLR, with the shortcomings that it has, but it's a really nice complement to a DSLR and especially for the times a smaller and lighter setup is wanted/needed (while travelling, doing cityscapes and street photography) and I do really like the X-T1.
