I agree it's a hypothesis=2E

I see it most often (with other lenses, too) when the sun is just outside
the picture area;  since the image circle the lens is projecting into the
mirror chamber is larger than the picture captured (either by film or by a=

sensor) the image of the sun - within the image circle but outside the
picture area - is on some surface of the mirror box=2E

The ideal mirror box would have perfect black-body surfaces from which no
light would be reflected; the oposite extreme would be white or reflective=

surfaces which would send the light from the image of the sun ricocheting
all over the mirror box=2E  The reality of course is somewhere in between,=
 as
black and non-reflective as possible (subject to marketing and cost
cosntraints)=2E  My guess is that some of the light from the sun's image
bounces around enough that it's eventually reflected toward the film where=

it looks like flare=2E
