Hi, I have posted a long message about all the screes compatibility quite a while ago, but can't find it to resend. Having no longer an SFXn, this is just from memory: 1) LX screens don't fit any AF cameras, because their frames are little smaller. 2) MX screens fit the LX and vice versa without any problems, even though the MX screen is a teeeeny bit larger than LX. 3) modern AF cameras use focusing screens which are ALL THE SAME SIZE, be it for the first SFX or the latest MZ-S, INCLUDING models which do not have interchangeable screens! For example, MZ-M split-image manual focus screen is the same format as the screen for SFXn and MZ-5 and PZ1p...! You can get the C74 MZ-M screen from Pentax Repair. On cameras with only center-weighed metering, it meters correctly (although it reportedly messes up spot metering and probably matrix too). You can even exchange the screen on MZ-5n and other models without changeable screens, it needs just unscrewing two screws. 4) modern AF screens, because they are smaller, will fit both MX and LX (and maybe others). 5)Basically, all the AF series shares same screen frame, which is smaller than pre-AF. Most of the M (ME-S, MX,MG,...) should share the same optical arrangement, but I dunno about the same frame. The K series is wholly different, and has both larger screens and incompatible. Fra
