I have an X10, and RX100, and a Canon G1X. I've only had the RX100 for a few days.
I need a camera for work that does macro reasonably well. The X10 was tough, so I set it aside for a G1x. The macro on that is even worse, but with the large sensor I could move farther away and crop what I needed. The RX100 is better, provided you shoot from the wide angle setting. The G1x was also useful to me as it has the articulating screen, which comes in handy for my work (I do engineering services on rotating equipment in the NYC office buildings, and I often have to take photos of equipment nameplates)
I shoot everything RAW, including the X10.
The G1x has fantastic IQ. It is also slow, big, and heavy. After seeing the IQ and small size of the RX100, and the fact that it is ok for work, I am planning to sell the G1x.
I was also thinking of selling the Fuji. With the G1x having replaced it as my every day carry camera, I used it mostly for dedicated street photography (which it is great at), and as a small elegant camera to be used in restaurants and stuff like that where I would like a small camera and no flash.
However when I took it out the other night, I was reminded that the Fuji still has many advantages over the RX100. First, the great optical viewfinder. Second, the flash shoe (and I have a Fuji flash). The speed with which it can be brought into operation. The manual zoom, and the threaded cable release, in which sits an Abramasomn (sp) button. Also the dedicated exposure comp dial was nice, altho I have assigned that function to the lens dial on the RX100. The RX100 has more p&s limitations.
I have to say tho that it looks like the RX100 will also be a great street shooter 'from the hip'. I put it in MF the other day and it was really fast. STill, I think the Fuji, with its choice of viewing modes, is better.
So I've decided to keep the X10, and the RX100, and get rid of the Canon. I'm lucky that I have been able to have all three at one time.
The Fuji's battery life is ridiculous, and the Sony doesn't seem much better. Sony's lack of a manual and battery charger is annoying, altho fixable via ebay.
However if I were facing the choice btw an X10 and an RX100, and could have only one, that would be tough. The Fuji is more versatile, and I think a better street shooter. The Sony is better IQ, and of course is smaller. Would probably depend on what I am generally shooting.
