According to Fuji the coldest temp's that their weather sealed lens and work in is 14 degree's F, I am assuming the same could be said for the XT-1. I live in an environment that experiences a lot colder weather, plus I travel to areas that have minus degree weather. Has anyone used their gear in extreme cold and hot areas without problems. I am looking to purchase Fuji gear, I am a nature photographer so I am out in a lot of different types of weather. I am currently shooting with FF Nikon gear, I have never experienced any failures in extreme hot or cold.
Thanks
