I can't speak for the Moultry camera but if I remember correctly with my Deercam, they suggested 100 for the clearest picture out to ten feet, 200 for good quality at a slightly farther distance(can't remember) and 400 for the farthest distance. The main thing that I have learned to avoid pictures of animals too far away to see, set the camera up with an obstical at the maximum range like a large tree or hill and set it up facing away from the sun. Hope this helps.
