I am leaving for a trip to orlando, fl tom and love photographing disney. I went during june and with the family rwlized my af was front focusing and ruined a lot of pics. Since then it jas been fixed. Just curious if I should bring the 1dx or 5d3 for this trip it will be hot and may rain. I may only get 3-4 hrs a day to shoot. Would the 1dx be overkill? Or shoukd I bring the 5d?
