My Sigma 17-50mm arrived today, but the autofocus doesn’t work on my camera with ftz. On the box it says the lens is for Nikon D. Is there a newer version of this lens, or do l have to update the firmware?

What version of the lens do you have? There have been several revisions. The current one is Sigma 17-50mm f/2.8 EX DC OS HSM. It looks like this.

Current model 17-50mm

This model should work. Check to see if the AF switch is on.

Older models may not be compatible with the FTZ.

This model cannot be updated by the user but it should not be necessary.

My lens looks like this, but l am a little puzzled by the box saying for Nikon D
