Hallo; does autofocus actually work with the Pentax K10D and Tamron 18-250mm?

If so,how good/fast is it?

  • Can you be more specific as to the lens? Some Tamron 18-250s have in-built motors, some don't. Jul 15, 2011 at 17:02

If the version of the firmware on your K10D is at least 1.30, then autofocus will operate with all K-mount variants of the lens. If not, variants of the lens that do not have an AF coupler at the lens mount (if they exist for the K mount) will not be able to autofocus.
