I have a new to me Pentax LX. It has a matte screen with a very faint centre circle. From this mir.com
page it's possibly a SE-25, but from the descriptions it might also be a SA-21, SA-23 or SA-26, or even possibly a SD-21 if the description rather than the picture is to be believed. I didn't worry about it when buying, as one of my MXs has a matte screen (presumably a SA-3 from this bdmitrov
page), and the MX is lovely to use. But I'm having real difficulty focusing with the LX. I read somewhere that the MX viewfinder is much brighter than the LX viewfinders, and that this has an impact; I didn't expect this to be such a big deal.
Anyway, the way forward seems to be to buy a more standard split image/microprism screen, presumably a SC-21. But the usual flea site only seems to have very expensive focus screens on BIN, and last time I looked didn't have any. Can anyone (a) advise me and (b) suggest where I might be able to find one? (My usual goto site
ffordes doesn't have one, not sure where else to look.) Or (c) suggest anything else that might explain my focusing difficulties...
Thanks!
