50/1.2 + 52-49mm Step Down + CP?

Good morning. Has anyone tried using their 50/1.2 with a 49mm CP filter with the aid of a 52-49mm step-down ring? I'm wondering how much vignetting there is, if any. I'm hoping it's negligible because of the APS-C crop factor. Thanks!

I use 49-52 stepping ring &CPL all the time. Even on 21mm Ltd. No vignette on the wide angle, the wider aperture, I have no experience with.

Edit

Ignore me

I just realized filter size on 50/1.2 is not 49

On film the K50/1.2 is prone to vignetting more so than the other K series 50/55mm lenses.

I use a step-down ring on a Nokton 58/1.4 without vignetting on APS-C,
so I wouldn't expect you to have trouble only going from 52mm to 49mm.

If you don't have a vignetting problem with your 58/1.4, I agree I shouldn't have a problem with my 50/1.2. Thanks!
