My GR (3 [x]) has developed Sensor Dirt Spots and ultimately I don't think it matters much but it bothers me a little bc on the one hand this is just what you get when u carry a camera in your pocket almost literally every day, but on the other hand it's only been about a year and this one has a dust removal system so it's sad to see it develop this problem so quickly...
I found... not a disassembly guide so much as some person on DPReview forums who took apart a regular GRIII to address a scroll wheel problem and took a lot of pictures of the process but wrote Zero text no words no description of what they were doing in each step... https://www.dpreview.com/forums/post/65491842
So if this gets annoying I might try to follow that Non Instructional Guide and just kinda hope/assume that everything up to the lens is the same in the IIIx
but I really don't want to take it apart so I'm going to wait
