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!

If you shoot on a windy beach often and come home to find the front element coated in salt spray you will start using clear filters for protection.

i put one on all my lenses as soon as I take them out of the box and they very rarely come off.

i always get the best quality filters and have never had any image degradation problems due to a filter. Avoid the cheap brands and you will be ok.

landscape photographers use filters such as polarisers and nd’s all the time and a lot of these are cheap versions and they never complain but again if you use top quality filters you won’t have any problems with image quality.
