I kept my Nikon D40x in a hand-bag and put it in my closet. I left it here for about 2 weeks... When I took it out yesterday, I can see the water on my lens and my camera's LCD screen... it's little tiny water which I believe it's come from the air... Because we always keep the air conditioner running... Will the cold air kills my camera? That's what I am afraid about because my camera's shutter speed is not working any more... Maybe I didn't set the correct shutter speed... I am totally new to photography.
