D5200 Autofocus Lens
I want to buy a 70-200mm f/2.8 lens for my Nikon d5200 but I am getting confused by all the choices out there. The d5200 doesn't have a built in autofocus (right?). I understand the Nikon lenses I need to buy have AF-S in their name. What about Sigma or Tamron? How can I tell if it is compatible and will autofocus?
I found a few on ebay but can't figure out if these will work:
"Sigma APO 70-200mm F2.8 EX DG MACRO HSM" & "Tamron AF 70-200mm f/2.8 Di LD IF Macro Lens"
Yes - AF-S stands for SWM - Silent wave Motor.
Sigma lenses named HSM will aotofocus with D5x00. (Hyper Sonic Motor)
Tamron lenses named USD will so. (Ultrasonic Silent Drive)
BUT both Sigma and Tamron has lenses a Little older with inbuild motor with no designation.
This is the case with the Tamron, you mentioned - it comes with an in-buildt motor for Nikon. (read DPReview on that lens.)
Means - you can use both of the two lenses you mentioned.
