Specially one trip this winter the temperature peaked to -25°C one evening when I was just outside the cabin taking pictures of Svalbard Reindeers (Rangier tarandus platyrhynchus). When I was done I brought the camera into the cabin where the temperature was above +30°C. That is a sudden 60 degree rise in temperature. The camera was inside its waterproof bag when i went Inside, but it must still be considered rough treatment.
I love my little X-T10, It is everything I hoped it would be.
