Hooray for the X100. I bought one recently, and I find that it is all that it promised to be. Great lens, compact, looks good, joy to use, great sensor, legendary fill flash and exposure, and about the same price as the Zeiss 24/1.8 for NEX-7 alone.
Lots of internet whiners want to complain about irrelevancies. I found them very easy to deal with. The AF speed and accuracy is fine. Not quite as good as my Nikon SLRs, but that's OK because I have a Nikon SLR for that. You can set it for hyperfocal/zone focusing, which solves a lot of the AF issues. Also, it is apparently programmed to reset AF on every shot, which makes taking multiple shots difficult. The solution is to put it in MF mode, use the AFL button to set focus, and then shoot as much as you want without AF lag. Three or four days with the camera and you'd figure all this out; most people just want to talk about it online apparently. In many ways, I think it is still the best compact/large-sensor cam out there. But, that depends on your overall approach. For portraits and landscapes, I'd rather use my Nikon SLR, and I'm mostly a one-lens guy anyway, so the single lens doesn't bother me.
