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

Let me start off by saying that I'm typically not a filter guy. I don't use any filters on any of my lens, unless it's for special purposes like ND and polarizers (and very rarely as well). I followed the (somewhat common) mindset that if I've paid a good amount of money for top-notch glass, I don't want to put some cheap glass in front of it. I've rocked multiple big, heavy, large front lenses like the Sony 100-400, various 70-200 including the IS ii, 85mm f1.2,... with just their hoods and no filter needed.

But now that I just got the RF 50mm f1.2, the front moving parts of it got me a bit concerned (and I noticed the previous EF version also had that). So for you guys who have been using them for a long time, do you feel the need to have a filter to prevent dust from getting into the inside of the lens? Is the weather seal reliable? Are some blower squeezes at the end of each session enough? If you use a filter, which one did you go with? Did it affect the IQ in any noticeable way?

Any input is greatly appreciated, thanks in advance!

Yes, because that's the only way to weather seal the lens fully.

Do you have any documentation to support this for the 50L or newer RF lenses? I've seen that specifically mentioned by Canon on a few older L lenses, but not for any of the newer ones.

Are you the same kid somewhere in this thread who said filters are just for changing how an image is recorded? It's pretty common knowledge UV filters are mostly used for extra protection and weather sealing. You should just call Canon and ask a tech rep rather than writing so many replies to this thread.

I'm the 'kid' (a very young 58) you seem to be referencing.  I was referring to the meaningful uses of filters, not the frivolous ones.
