A very interesting explanation . Thank you Paul .
I have both lenses , the 28mm and the 40mm but never saw that phenomena .
My understanding is , that you will not see that penumbra when the light comes from the side or from behind the camera . ? ? ?
Also , I think that the issue will be less obvious when using a smaller sensor like with my CFV-39 and CFV-50 . The sensor size here is 37x49 mm only .
I never shift more than 5mm with the 28mm lens either way and 15mm with the 40mm .
