A camera upgrade question

[marwamorgan]

Hi!

I have a Nikon D40 with 18-55 lens and sigma 70-300 lens....
I'm upgrading this year, I thought of getting the Nikon D-5000 or D-5100 or D3100 but I have a real problem with Manual focus as I have bad vision so I need cam that supports auto focus with non AF-S lenses as well as AF-S (and that was my real problem with the D40), My budget is 650-700$ so I can't afford to get a D-90,I thought of getting a canon but It won't work with my sigma lens, plus I've been a Nikon user for over 4 years so I got used to using it.

Any suggestions?

So your only criterion are (1) has a focus motor built in and (2) $650-$700?

A D50, D70, or D80 should fit the bill (predecessors to the D90).

As the above post said the cameras you can consider are Nikon D80 or buy a refurbished Nikon D90 you might get it at $700

Used, or as noted above, a refurb might fit the bill
