Yip, the shim is thin, but I did it, by putting the shim on a cardboard box and taping the shim to the box with the scotch tape, and trimming it using a surgical knife, bought at my pharmacy. You just
carefully lift it with your tweezers and using the smallest screwdriver, slide back into place. Just after you remove the shim, you put the cap on the mount to keep the dust out, giving you time to do
it without worrying about dust in the camera.
I tried cutting an old focusing screen once for my K-x, but learned the hard way how sensitive they are, promising to avoid working on one again, as far as possible...
