Sigma 10-18mm F2.8 Contemporary XF Mount Infrared Lens Testing

I recently got a modified infrared X-T30 II and i’ve been testing some of my existing lens collection to see if they are compatible with infrared photography. The problem is that not all lenses are compatible with infrared modified cameras. Due to the construction of the lens, it can sometime produce a ‘hotspot’, a bright patch in the middle of the image that is not consistent with the rest of the image. At the time of writing, there didn’t seem to be any information on whether or not the lenses I tested produced these hotspots so I took it upon myself to test these out.
