Hi, I am a student and my small room will not be inhabitted for almost two months. Because each room in our flat has its own heating, one can regulate the temperature. In order to save costs, I am shutting down the heating in my room. So, it will be cold in the room. How cold, I'm not quite sure, but outside the temperatures will be below zero degrees celsius or below thirty two degrees fahrenheit, reaching maximum temperatures between -20 ºC and -4 ºF I have left two (mechanical) cameras, and four (mechanical) lenses in the room. (No digital or autofocus equipment). I have also left a small generator and two strobes. Everything is covered in plastic bags. I wonder if these temperatures do something to the equipment. It is the first time I do something like this. Thank you, kind regards, igmolinav.
