Hello, Im wondering if any of you have experienced problems using the Sigma 85mm on a mirrorless Canon body. Mine seems to be triggering the peripheral illumination setting and creates circular shadows throughout the frame. Shutting off the feature only darkens the entire frame. Any thoughts?

According to this article, https://www.lensrentals.com/blog/2012/08/canon-illumination-correction-and-third-party-lenses/, it's telling your body's lens corrections that it's a Canon EF 17-35 f/2.8, so it's no wonder the camera corrections can't cope at wider apertures. Maybe try some positive exposure compensation just with that lens if you are getting the entire frame too dark when you switch the peripheral illumination corrections off.
