This is not to challenge your knowledge, I have no knowledge whether P&S has shutters or not, but from derevation, how can P&S has shutter if we are able to have live view of image on the LCD?:think: I guess it should only be digital shutter, because for most P&S ,we can select silence mode, you totally don't hear a single sound at all, if there is mechanical shutter, it will be very hard to make it totally silence, right? Just my guess from my low IQ.
