Two lenses, two bodies. And it’s something that I don’t think anyone else has seen. So logically it seems likely to be something in common with your two situations, but not to do with camera or lens. This leaves two possibilities;

1. Filter - are you using one, and did you use the same one on both lenses?

2. Software. Assuming you’re shooting RAW, which converter are you using and was it the same both times? Can you retry with a different RAW converter? Also did you by any chance also shoot JPEGs at the same time? In which case, is the spot on the JPEGs too?

I don’t know anything about the above comment re near infra red. I have the same body and lens and have used for many 100s of images at all focal lengths in different lighting conditions (but not under African sun) and never seen such an artefact.

Very interesting though.
