I had about a mile to go down in a valley to get where I wanted to be and figured down in the valley it would probably get a little colder. YUP!!! I was right.
I know this is not a controlled scientific test for using the Canon Mark 3 & the Pentax K10D in cold weather. It is the two cameras being used out in the field in cold weather. I really didn't notice any difference in the way they handled. I did have fresh charged batteries in both cameras. I was out of the camera wagon for 20 to 30 minutes so the cameras I think had a chance to be affected by the temperature but IMHO they didn't seem to mind.
If you notice anything unusual about the photos that could of been caused by the temperature please point it out. The EXIF data is available on the individual photos but not the photos with a insert.
If you ever are lucky enough to be in the Rocky Mountains or around elk in the fall and you get to hear the Bulls bugling it will send a chill down your back. At times you can bring a bull in 25 yards or less and he is fighting mad.
