I tried the xpro1 but didn't like it. Didn't like the optical viewfinder as the lens covered the bottom 1/4 of the frame. Things like that would drive me nuts. Also the EVF was poor.So if I was to go mirrorless, it would have to be one with a good quality EVF.
That's what I like about the X-E2. I also like the fact it has good AF performance, although only with the centre point which is the only thing stopping me placing an order.
The thing about the X-E2 for me is, it's just so damn beautiful. It's like the Aston Martin of the camera world. I know that shouldn't matter, but the camera has a strange allure over me.
This Fuji would be a "toy" for me. I've tried the X-100 so I seen the viewfinder in it, and you are right, it's not great. It sucks actually compared to a DSLR, any DSLR.
Hence I am willing to forgo that aspect completely and get the X-M1. Seeing it can be had for £270 at the moment.
This post is way off topic, but I think it helps with RL's and An Exception's debate over numbers vs experience - here's my own experience with an X-Pro 1 and a bit of pixel peeping to see where it stacks up against a bunch of Nikons.
RE: The viewfinder. Leica viewfinders are a lot like the ones you find on the X100/XP1, and I actually prefer them to an SLR prism since it allows me to observe a scene as it is instead of what the lens sees. While being able to preview what your photo will look like is nice, I find having that more direct view makes composition easier and it allows me to work a scene more thoroughly. I don't really need to see what the lens sees since I have a fair idea of what the photo will look like in my head anyway. And unlike a DSLR, I can shoot with both eyes open and have the framelines 'float' across my entire field of vision. Finally, not having the viewfinder black out during each release helps a lot since I know exactly what moment I've captured, and again my viewing of a subject is as unimpeded as possible. There are downsides of course, the lens protruding into the VF is one (not much of an issue with the pancake lenses though), as is the parallax error when you focus closer, but those are also issues with rangefinders so they never bothered me that much. I only use my SLR for focal lengths above 50mm now, everything below that is taken care of with my XP1.
The 35mm is an excellent lens too:
Aren't there still problems with fine detail when using the X sensor? The watercolour effect? It's a lot better than it was but its still there as far as I've read up.
I would say that default conversions generally tend to be a bit more blurry than other similar sensors, you generally have to be a bit more aggressive with sharpening to get the best results. DPR's studio scene conversion seems to be out of date, so I put this together: top two are D800, D4, bottom two are X-Pro1 (DPR's conversion), D7000, and the patch overlaid is my own default conversion from Capture One (I get similar results with LR5 but I haven't dowloaded it to my PC yet):
The DPR conversion really looks like crap in comparison, I think that must be with an older version of ACR.
