It doesent have autofocus motor build in, so u need to get some special lenses for it if u want to use auto focus, range of those lenses is limited. It allso has only 3 focus points. If u absolutely have to get nikon get d80, those cheaper models are stripped so much theyr a joke. Still id suggest you to buy 450d unless u want to pay little extra for 40d. U should read some comparisations between d60, 450d and iv heard good thing about sonys too.
