Evening all, Went on a hike today to test out the 40D I just picked up yesterday. The temperature was cold at - 10 degrees celcius and I was out for over 4 hours in the cold with the camera and took roughly 58 shots total. After I got home and let the camera warm up a bit I was surprised to see the battery still had a full charge. I was really happy with how the camera functioned in the cold weather. As well, I did not run into any problems such as error 1, error 99 and there does not seem to be any hot pixels I can find. I had heard of many problems with this camera from several members on different websites but so far I think I got a keeper. Any way, I did not really like any of my shots from today as I just didn't see what I was looking for but here is a couple from the hike. 1. 2. 3.
