comments: There is a strange greenish area, slightly above the centre of the image. I think it is caused by the non-coated glass Zayla used. If this was caused by coatings in the lens not working for IR, it should show in the centre as on the Minolta 7i and later.
If you squint your eyes, I think you can see a bright spot in the exact centre, extending right until the greenish area.
Thanks again to Zayla for these shots, shown in this thread at
