It depends on how you define quality, perhaps.
I'm not that familiar with digital cameras in general, but I did buy an X-Pro 1, so I'm somewhat familiar with that one. The overall quality of the camera and its image capturing capability is high. I'm basically satisfied with mine. However, it had a few too many loose ends at release that I think reflect quality issues.
For example, the framelines in the OVF are not especially accurate on the X-Pro 1. Autofocusing, especially with the 60mm lens, is slow and it hunts a lot. The video capabilities of the camera seem to be thrown in as an afterthought. There isn't even an external microphone jack. Why bother burdening the camera and my pocketbook with such an ill-conceived and poorly executed frill that can't be put to any serious use? Plus any fault or shortcoming that someone asserts "could easily be fixed in a firmware update" is evidence of a rush to market with trailing loose ends.
I'm sure some people would not consider these faults to be evidence of poor quality, but it's a matter of perspective, certainly.
You can certainly take to task many of the new cameras that have come out...but I find it hard to diss Fuji's offerings. Both the X100 and X-Pro1 are innovative digital cameras that offer useful options that no other cameras offer. I feel we are still in the infancy of digital camera design. I'll take what I can get knowing damn well there is no such thing as a perfect camera and that bugs are just part of the territory when you are using a computer camera.
