Take your time. The reason why you can take fast 12MP photos is because the system uses pixel-binning to make the dark and underexposed 48MP photo it captured during the short timeframe. In the same logic, if you want to get a good 48MP image you need more time since there is no leeway for pixel-binning. Actually, an unofficial HDR+ enhanced 48MP photo needs well over 10 seconds to shoot, hence why it is not in stock cam.
