That’s a good question. I’ve been using the NISI adapter, squarehood and filter since I saw some dust there at f16…It can be removed on post production in eg. Lightroom. But perhaps there’s a way to deal with it besides sending it to the shop on warranty, as the problem will come back.
Here it’s with the original GR adapter:
But there are interesting attempts as below. I’ve not yet got round to trying this shake shake method.

Here it’s with the original GR adapter:
But there are interesting attempts as below. I’ve not yet got round to trying this shake shake method.
After a few months of intense use I found four specs visible on the sky or white background photos taken with F16 through to F11. It can be easily removed in Lightroom or other app. But I started using the nisi adapter plus filter and hood because I do some landscape photography and it does bother me if it was to get worse.
Due to rectracting lens system of GR I always used GA-2 adopter with filter on when photographing in inclement weather conditions, especially with wind blowing, be it in rain or on the beach, something I recoomment to everybody. Unfortunately, dust will get in but I should be less a problem with IBIS and sonic cleaning.
