I like both the D600 and W800; I can't figure out if I want still picture or video quality as a priority. Regardless of that, got a question for you D600 and W800/K750 owners. How quick are they at taking pics? I mean, from selecting the camera application, to focusing time, time to actually save the picture, etc? Its one thing I haven't seen much of anywhere in reviews. They've mentioned picture quality, which is good on the D600, great on the W800.
