For Nami-sama: Fringer FR-FTX2 [NF-FX II]

This is an item recently purchased from Map Camera. I am listing it because the autofocus would not work properly and the camera would freeze when using a Sigma F-mount lens with my X-H1. Unfortunately, according to the Fringer website, it seems to perform poorly with older sensors and processors. Newer models appear to work.
Thank you for your consideration.
