That usually means you need one of the screens designed for astro/microphotography. Screens usually come in both clear ground glass and clear non-ground glass. The might have either a simple circle in the middle or some kind of scale. I've owned at least one of the LX ones which was an SC-21 or SC-11 I think. Microprism screens don't work for focus under those conditions so you use a screen without one that transmits as much light through as possible to aid in getting a real focus. Kent Gittings

There might be some terminology problems also. I need matte screen but with no markings on the screen. Look at http://www.bdimitrov.de/kmp/focusing/screens/index.html This supposedly lists all the Penatx made LX and MX screens. The one I was looking at was the SE-60 "Plain Matte Field". This is a modern, brighter LX screen, that someone just advised against using in MXs. Of course it is possible that someone else made plain or clear screens for the MX, this site only lists the Pentax made screens. Can you give me the model number on the clear screen you have? Can someone please clarify what crosshair means? I would still appreciate any insight anyone has on screens in MX. What do you use, how does it work, how it effects lightmeter? etc. thx.
