Details start to get a little mushy at ISO 400 and I'm not crazy about the automatic white-balance results in the mixed fluorescent and daylight, but this ISO 400 shot is quite usable.

The exposure is darker and the white balance warmer than I like, plus the JPEG processing and noise reduction seem a little overzealous, but the ISO 3,200 photos are usable. I won't know how much they can be improved until raw support becomes available. Beyond ISO 3,200, a lot of hot pixels appear.

Sony's HHT mode combines six exposures into a single image optimized for dynamic range. Since the mode operates faster than in previous models, it's a lot more useful.
