Hoods with a rectangle mask reduce the unneeded light even more,

That's a very good suggestion. Thanks.

In this specific case, the glare is caused by a circular element, so provided a circular mask works well, there is in theory no need for a rectangular mask. However, there are lenses for which circular masks do not work well (e.g., my New FD 35-70/3.5-4.5 zoom) and a rectangular mask could be a great improvement.

More generally, a rectangular mask can reduce veiling flare from coatings and improve contrast.

I think I'll try your suggestion in my next iteration of my masks. A good starting point is probably rectangular masks whose diagonals are the same size or slightly larger than the diameter of my existing circular masks.

Regards,

Alan
