I'm very curious about this camera. Has anyone compared the raw files with the Fuji x-Pro1 raw files? I'm trying to decide between the two cameras. My prints are 24 x 30 inches and larger, usually from stitched files out of a Canon 5D2. Any help would be much appreciated.
Very different cameras. I have shot with both recently (the X-E1 actually), but not side-by-side. For what it's worth, the Fujis are much better cameras - as cameras. They will also provide amazing IQ at ISOs up to 6400. The Sigma is more of a base-ISO beast.
The Fuji also produces superb jpegs, especially with skin tones. The Sigma is a RAW-only proposition.
In absolute terms, however, under ideal circumstances, the Sigma will produce a more detailed image.
Think of it like this: the Simga is a mini tech-camera with a fixed lens. The Fuji is a modern system-DSLR type camera by comparison. Personally, I will end up with a Sigma and keep my Fuji X100, but continue to be tempted on the "X" series.
