The Pentax LX was specifically designed for environmental extremes. For example, the motor wind battery case can be detached from the mechanics (like the MX) and a cord used so that you can keep the battery warm in your pocket. It was designed with the best seals of any camera ever made, save underwater designs. It was selected by National Geographic as their choice for 35 mm format for an expedition to the Antarctica. (Unfortunately, the expedition was canceled.) I have used one of my LXs for extended durations down to -30F in Quebec with no problems! It can be operated using fully manual shutter. Before you bring the camera indoors, place it in a Ziploc bag until it warms up, and you won't be plagued with condensation. FYI, the light meter worked fine. I just had to make the usual corrections for snow.
