I got curious how much I could improve my current IR setup and of special interest is using wide-angle lenses. By wide-angle I'm thinking 18 - 24 mm, full frame, though could go to 28 mm and do more stitching. My IR is done on mirrorless Sony, so E-mount lenses or anything adaptable goes. I need to use filters, a large aperture is not necessary as primary used is stopped down and quality across the frame should preferably be even. High contrast, reasonably sharp, no hot spots or other artifacts. Any recommendations? Zooms or primes are both ok.
As a side note, I recently tried IR with a Zeiss Batis 25 and it was disastrously bad, having both hotspots and general loss of microcontrast. Just proves that visual performance predicts very little of the IR performance.
