Lovely mallard!!
To prevent condensation, I double wrap mine with the lens still attached in plastic shopping bags before bringing it in the house, klm, then leave it in the bags until it comes back to close to room temp. I've done that will all my cameras (even the old SLR) and I've been told that digital equipment is even more sensitive to moisture than the older, non-digital equipment. I keep intending to buy large enough ziploc bags to accommodate the camera, but you know how my memory isn't....and the double bag system seems to work just fine...
