Hi, thanks for the response.
No, no focus peaking on. I've tried pretty much every combination of iso, shutter speed, aperture, PASM, switching to Auto, switching off the exposure preview... everything I can think of. Hence asking here. I drove out to a store last night to have a look at their display model. I couldn't quite get it in the same environments I have issues with, but it was certainly less fuzzy. Even sticking the lens cap on to *try* and simulate pitch black, the screen had hardly any snow at all. Mine goes crazy. Think mine's just a bit sensitive.
