don't say that, the Canon D Rebel XT will autofocus with ALL Canon EF mount lenses, the Nikon D40 will not focus with all Nikon F-mount lenses. I personally think that the D40 is an absolute horrible Digital SLR made purely to scam buyers out of money. Look at it this way, the D40 can only use AF-S lenses to autofocus. AF-S lenses cost more than their older AF-I counterparts. The D40 is a budget camera correct? However, by saving 3 or 4 hundread dollars in getting the camera, it potentially costs you thousands more in lenses, it's a scam to get Nikon more money! and if the people don't buy the lenses, they out grow their D40s really quickly and buy a D80 STILL getting Nikon more money. Also if you decide to keep a D40, you get only 3 AF points compared to 7 on the XT. I may be a Canon fanboy who went with the XT myself, but even most Nikon users will tell you, stay away from the D40 and D40X cameras, the only people who will recommend them are owners of D40s who want to justify their purchases.
