I have a bit of format schizophrenia. I started in digital with a Nikon but switched to Canon (which I use mainly for telephoto zoom, though I have shot weddings and portraits with it). Then I added a GX7 because I wanted small, lightweight, and diminutive--and I didn't want to stick with just the single focal length of the X100. I picked up the Panny 14/2.5 and 25/1.4 which I use currently. Then I started getting crazy and added a Mamiya RB67 6x7 medium format film camera to the mix. It's a beast compared to the GX7 make no mistake, but contrary to the advice many have bandied around on the internets, the RB is a capable environmental portrait/street as well as landscape camera. I like lightweight but there's also no way to replace the uniqueness of a 6x7 B&W negative, especially in the highlights and the way film falls off as the tones move toward overexposure. I compared the RB to my 7D setup and found them comparable (not "the same") in bulk. All that background aside, I'm wondering if anyone is using the Fuji X-T1 in addition to their MFT setup? I know some have FF gear so that's no surprise to me. But I'm finding that maintaining a minimum of multiple formats has advantages that completely switching formats precludes. I am considering replacing my 7D with something and the Fuji X-T1 in particular seems to be a good fit. It would seem to complement my MFT setup quite well. Zack Arias really likes it and David Alan Harvey has recently been posting photos from a trip to Brazil in which he used the X-T1 and his results are great (part of which is because he's a stellar photographer no matter what setup he's using). The thing that worries me is the autofocus versus the other sane option (the E-M1) and the fact that MFT has a more complete lens selection, including longer focal lengths. The reviews I've read about the X-T1 with the 55-200 zoom seem to indicate that people who have actually used the thing in the real world are quite happy with the lens performance in both IQ and autofocus. It's always interesting to read the reviews on B&H's website as you get a fairly even split on almost every item of people who think it's great and people who say the exact opposite. The Oly 75/1.8 is a very attractive medium telephoto option that I don't see the equivalent of on the Fuji side. In point of fact I don't see much fast glass on the Fuji side at all save the "standard" lengths. Even so, the people who have bothered to use the Fuji in demanding situations speak highly of the glass and the Fuji sensor so I'm definitely torn. In the end I'm sure it doesn't matter so much as either an E-M1 or X-T1 will give me excellent results. But I'm curious what others who use both MFT and APS-C think about having both formats handy so you can use each to their own strengths.
