Any AF camera will have trouble with snow, AF works by judging the contrast (Difference between light and dark areas) of the subject. Anything that is all one color with no shadow lines or prominent texture or color difference to create contrast will be IMPOSSIBLE for AF to lock on to. Also, anything that is too bright or too dark will give AF fits. Even the human eye needs to find some kind of feature or shadow area to focus on. When I want my AF lenses to retract all the way to infinity for storage I just point the camera at a wall or ceiling that is all one color. Fools the AF everytime, causing the lense to go from one extreme to the other.
