Can you knowledgeable folk help please.
I want to get a used Tamron or Sigma 70-300 for my D3100.On a budget.
I am confused as to what lens has the internal AF motor.
I think Tamron A17 does not have one. I think the A005 and AF70 does.
On Sigma I think the only one I know is the DG Macro.I think the DG APO does not have one.
I would be grateful to have these thoughts proved or disapproved and any others you may know. Thank you.
