Have your heard the same story guys????? I had sony but i switched to nikon....

i am not sure about that as i never had any sony digital cam, but we can see it at the review

Websites of Sony, Nikon, and Canon show that their DSLRs' operating temperature range are all Oº to 40º C (32º to 104º F).

It should be running ok in that temperature. Ive heard from friends and colleagues that the first thing that will start to go crazy in extreme cold, like for example shooting in antartica or alaska, or on top of Mt. everest -- is the battery. some high end cameras like the nikon d3/d700, canon 5d/1d(s), olympus e3, pentax k20d and others have some protection or sealing to prevent this. In extreme heat(dry), the LCD view starts to show the image previews a bit more darker than normal. In high moisture situations, several issues also occur for cameras with minimal or no weather sealing and protection.Condensation to the lens and also to the camera body overall.
