RF 50mm f1.2 users (and probably EF version as well), do you use a protective filter on it?

And now the simple question: Why are such filters not part of the original lens? Obviousky because of disadvantages... No optical engineer would add an additional plan parallel element without critical need since it will degrade contrast and adds flare. 50% of our calls concerning UFOs or strange nocturnal light phenomena at my observatory origina from pics taken by people with front filters. Its always my first question. When I hear frpm a second moon or a unknown "comet".

Thanks, that's a good angle (no pun intended) to the problem. Guess if Canon engineers were to do it, it would need to be a curved glass piece like the front element of similar lenses (like RF 85mm 1.2 I think?), not the typical straight filter glass.
