So it just got cold here in Utah. I'm wondering how cold is too cold to take my camera out for a spin. I read in the manual that the operating temperature is something like 32-104 degrees Fahrenheit (0-40 Celsius) but all it says is that the battery life will decrease as it gets colder. I know for a fact that my camera can be used just outside that range on both ends (at the very least 25-109 degrees F. That's about what my camera and I have seen together). But what's a reasonable range for safe temperatures to expose your DSLR to? I'm not really worried about battery life. Does it also have to do with what camera and lens are used?
