OK, sorry for the harsher reply before :) I do realise that the planar surface can change the light path, especially in superwide lenses. That is, in all my shooting situations, I haven't encountered a single problem when it added to the aberrations, even with 12mm lens. OTOH I can imagine that with some lenses, it could. But I haven't seen a single one. Anyway, most photographs are bad enough art that the issue doesn't matter to me - when my photograph is good enough photograph some small quality loss doesn't matter to me. And most amateurs are today just nitpicking over quality of the technical side, not quality of the photograph :) All good, frantisek
