Unfortunately it seems older versions of this lens need a firmware update. I have this lens and it works well with my DSLR's it refuses to focus on my Z7 w/ FTZ. The copy of this lens I bought for my father (3-4 years newer than mine) works without problem on the Z50 I subsequently purchased for him. If the seller is giving you headaches about returning the lens, you may wish to contact Sigma to see what having the firmware updated would entail.

Best of luck.

Thank you. I contacted Sigma today and they told me to send it in for an update of the firmware. In their opinion this will do the trick. I will give it a try and keep my fingers crossed. The update is free of charge.
