Today I had an peculiar request from a customer in my shop. He told me he was going to Dubai, so he needed a camera that would operate in 50 degrees C (122 dgr F). I checked a few websites, and between the ones that show in the specs the camera's operating temperatures, noone exceeds 40 dgr C (104 F). I found this a bit odd, but being Norwegian, what do I know of hot climates and photography? I've only worried about cold fingers, dead batteries and condensation before. The customer claimed his nex simply shut down when it was hot enough. Don't people photograph in warm countries all the time? Do the cameras sold in dubai have special heatsinks? Or maybe they sell watercooling systems for sensors as accesories?? Is my customer excaggerating the grossly? Or am I missing something?
