In reply to mountain_bikerider: the age-old "issue" that people always voice about lower-end Nikons not having a focus-motor in the body, really makes sod-all difference to you, as I have come to realise from owning Nikons for the last 5 years.
If it was a genuine issue, do you really think a company like Nikon would have let it continue, when they've got Canon to compete with?
To cut a long story short, it's not an issue because the lenses that you will want to use with your focus-motorless-Nikon bodies, will have their own focus motors. End of!
