What are Nikon cameras that have a focus motor within the body and NOT the lens?

Would you recommend such cameras?

D90 and above models

D90, D7000, D300, D700, D800
They are a good buy, as you can cut expenses buy getting AF lenses which are cheaper than AF-S lenses.
But AF-S lenses the autofocus is much faster and smoother. Also its better to have body motor as you have the option of using both AF-S lenses if budget permits or AF lenses if budget is tight.

But believe me D90, D7000, D300, D700, D800 are spellbinding cameras.

D90 and up.

D70, D50, D100, D200, D300, D700, D90, D7000, D1/2/3/4

Recommend. Only if you are keen to buy certain lenses new or if you want to hunt the used market.

D50 and up - you can see the drive pin on the mounting ring.

Sure, why would we not recommend such cameras.

Nikon D90, D7000 and anything higher. These are $900 and higher.
