Pentax MX focusing screens ...

[Godfrey DiGiorgi]

Seems to be a lot of K1000 lovers. I never had a K1000; this MX seems 
uncluttered to me: I like it. As I said in my other post, I prefer the 
LEDs in the viewfinder over the match needle setup as they help me see 
the meter reading in the dark, when I need it. In bright light, I can 
estimate exposure well enough and rarely look at the meter.

Does Pentax make a plain matte fresnel focusing screen with a set of 
scribed horizontal/vertical reference lines for it? I'd love to add one 
of those and get rid of the split image/microprism focusing aid.

thanks in advance,
Godfrey
