the past few home shoots i have done have raised a bit of a problem with my 5D i seem to be having problems with it steaming up when starting the shoot, it's so bad that i am now having to warm the camera with a hairdryer before starting, anybody else have this trouble ? never used to get it with my 1D !, thought it was the lens at first but it's defo the camera

guess i'll just have to stick to the hairdryer then
