You know that most people here are going to recommend the OMD! And by the criteria they're pre-selected to find important, they're absolutely right! Which might or might not have anything to do with YOU.
I have both and they're such different cameras that the technical considerations have to come in a distant second to WHAT DO YOU WANT? What are you gonna do with it, what strengths matter to you, what kind of shooting
experience are you after?
The OMD is a brilliant modern feeling and acting camera. It has a smaller sensor but its a really really good sensor. Some will tell you it will equal the X100 (or X-Pro 1) in image quality, but to me "image quality" isn't just about numbers, its about
quality and the Fuji's is different than the OMD's. You can perhaps ultimately get similar enough results if you're shooting raw and you develop processing pre-sets to make them look similar, but part of it is also how easy it is to get a particular result. The Fuji has its own look, its own color preferences, its own approach to high ISO treatment. I slightly prefer the Fuji in this area, but the OMD is really wonderful, so its more about preference than actual measurable things.
But 99% of the difference between the cameras is the shooting experience. They're both modern cameras, but both LOOK sort of like they're not. BUT, the OMD
feels like a thoroughly modern camera and the X100
feels sort of like a throwback to a different era. I love them both because I like both shooting experiences, but they're different. The X100 does fine for AF, but its not lightning fast like the OMD - just a fact - the opinion about the importance of that fact is up to you. I'm happy shooting with the Fuji in terms of AF for most things. For some specialized applications, I prefer the OMD, but usually when I'm using focal lengths that aren't possible on the Fuji anyway...
A lot of it frankly is the flexibility of interchangeable lenses versus having a single fixed focal length. Again, I love both, but wouldn't want to own the X100 as my
only camera. But I've travelled with only it and didn't feel like it was an impediment - you just get accustomed to shooting at the 35mm field of view.
And the other HUGE thing is the viewfinder. If you love shooting with an OVF, the X100 or X-Pro 1 is the obvious choice if you don't want to carry a DSLR or spring for a Leica. If this isn't a huge issue to you, the EVF in the OMD is better than the EVF in the Fuji, so this should be a big consideration. To me, the OVF is a HUGE reason to own an X100 and an X-Pro 1. To some people it either doesn't matter at all or may even be a negative, so there's be much less point in it for them. Where do you come down on this?
I'd say the flexibility of an interchangeable lens system vs the simplicity of a single fixed lens and the importance of the OVF should be your primary considerations. Both have good enough IQ and low light capability that those would probably be secondary considerations to me. The Fuji has a different look and feel to its images that to me are
qualitatively better (maybe not quantitatively), but may not be to many folks. But only YOU know how important these various factors are to you...
