I'm not sure if this has been handled in this thread as I didn't go through all the pages (maybe should have?). I have had K-7 with Ee-S bit over month now. I'm using it mostly with Samyang 85mm 1.4 and A* 300/4. When I adjusted the focus with shims, I found the best focus accuracy without the shims at all (not even stock shim in the camera). Is this normal? Samyang seems to be ok like this, but I still find A* 300 front focusing a bit. As there are no more shims to remove, I guess there is nothing I can do about it, yes? As I understand different cameras may be different about this (need different amount/thickness of shims), so is this just a "feature" of my K-7?
Furthermore, can the focus accuracy with Ee-s focus screen vary with the focus distance? I find both of these lenses be quite accurate in short to moderate distances (2-10m) but I get more front focusing in longer distances (>15m).
All in all, Ee-s seems to be working quite well, much easier to manual focus than with stock K-7 screen. Here are some examples with A* 300/4 (these show no front focusing in my eyes):
