Yesterday it was relatively warm. More like - 25 C, and I took my M2 with me on the way to work so that I could get fun pictures of people braving the cold. With folding-finger gloves the camera worked just fine BUT it was pretty hard to focus. The grease in my Planar had become very stiff. Still, everything was fine. Then I got on the bus. BOOM - camera, lens, everything, covered in frost. It was pretty funny. By the end of about a 40 minute ride all the frost had melted and evaporated. Then back out into the cold.
