Update: It's been some months, now, but I wanted to pop in and say that we went with the Canon Rebel, after going to the camera store, so my son could handle the options. He loves it and has used it a lot! He just got a 150-600mm lens, for Christmas and is delighted. It's great to see him taking to this artform! So far, he's manipulated the images to look infrared, but I think the filter is the the future. He likes to experiment. Thanks for your input, guys!
