If my cheapo PnS (really cheapo, but not going to say which model, just cheapo!) can survive snow, then your DSLR can survive some aircon.
There are obviously more treacherous conditions for a camera to be in than an air-con room. Please don't be silly.
You get the Nikon D3, and start to take pictures which make people go WOW! Then, you can start selling these pictures for a lot of money, and before you know it, you'll have $∞! Then with the $∞ you have, you can buy another D3! And it keeps on going!
THAT is the art of WOW!
* Important Note: Please feel free to substitute the Nikon D3 with a Canon 1Ds MkIII if you are a Canon user, or you can use the Pentax K20D if you are night86mare.
i have been enlightened!
