Nah, this wining was mostly heard from 'JPEG only' wannabe owners. Shot raw and shut it up has been the cure during the XZ-1 lifetime.
I already mostly shot 6000 exposures of JPEG with my XZ-1, with raw as complements from the earliest days of the cameras launch in January 2011. The lack of 'noise filter settings' hasn't been a single issue in any of those 6000 pictures.
Most problems with the XZ-1 has been with the video, and the fiddly control dial at the back. Still seems Olympus is not giving the attention to the PAL video format (25p 50p, 50i) world, which unfortunately moves my interest away to the Panasonic DMC-LX7 instead, the day when I need to replace my XZ-1.
