I’ve personally never used this camera, but you can find some great camera reviews for the D40x from other people on the CNET website located here. Hopefully this helps.
Have one, performs beautifully. Have taken 1000’s of pics with it w/o any problem. Except one: It fell (in the case) about 4 inches and dislodged something so the on-board flash doesn’t work. I can still use the ancillary flash unit on the hotshoe.
