RE: Nikon D40X
good camera, but by all means, not a professional camera. if you're looking to shoot on a casual level, then it's a great litte camera, just be careful when out in the field as the body is not well sealed at all. the kit lenses are horrible however. especially if you want to use them in low light situations. here's my set up:
all nikon
D200
D100
D1x
10.5 2.8 fish eye
