The Sony RX-100 lens is wide enough to allow holding the camera at arm’s length for a self portrait. Fill flash dialed back to -1.7 stops worked quite well; full power looks awful, the usual blow-out-shot-with-flash look.
As Photoshop CS6 doesn’t yet do Sony ARW (RAW) files, JPEG is all I can show. JPEG on the RX-100 is about as mediocre as on other cameras, which is to say that most reviewers will say it’s quite good. But the signs of compression are visible and I don’t much like it. But downsized for web display, it’s just fine.
At any rate, the image quality is massively better than 90% of the point-and-shit cameras in its form factor, so kudos to Sony on image quality.
Still, up in the mountains, the inability to use a polarizer (no filter threads) is a MAJOR drawback, as is the asinine requirement for in-camera battery charging, so I can’t do the battery swap thing or shoot while charging. Well, I have only one battery, so for now that is not a real issue, but it would be for most uses for me. Such as on my Big Ride where carrying a camera with one battery is a risk.
