I'm quite new to Fuji, having just recently purchased the X100T. I come from, and still am, an Micro 4/3 user. In my view, I don't see the X70 and the X100 as competitors. If I had decided one or the other was a good fit for what I wanted, I would not think the other was a reasonable replacement. Both cameras are quite nice, but I would say different markets in terms of filling what the prospective buyer is looking for. While I like the M4/3 platform, I chose the X100T over the Pen-F, and could not be more pleased with the choice. I am an old schooler, and the combination of old school charm, exceptional image quality, modern technology have all been perfectly combined in this camera. It makes we want to take a camera with me every where I go. I could easily do that with one of my M4/3 cameras, but there is some reason that this Fuji calls to me to do it while the others don't. I get exceptional image quality out of my M4/3 lenses, and it is a platform I am happy with. But this Fuji X100T brings an intangible to the table that makes it stand alone in my collection.
I really like this camera.
