Canada Rockies- did you find that when you installed the LL-60 screen you mentioned, there was a trade-off?

And still a light enough viewfinder with slower lenses? Or is this just not a possible/realistic compromise?
As you've probably all guessed I'm a newcomer to dslr and I've been a bit perplexed by a few issues I've had, when I've spent the extra money to step up from compact P&S and I was expecting to get back the control/functions and quality I had when I was using a 35mm SLR SP1000 a few years ago. I should have known things were not going to be so simple.
This thread and the info and links you've all provided have been an invaluable education, so thanks Frank, Marc and "Canadian" for pointing me in the right direction.
I have not noticed a trade off with the changed screen. It might be noticeable if you have a penta-mirror viewfinder, but with the pentaprism finder of my K10, I don't notice the loss of light. I did not mention that the metering with my DA lenses did not change noticeably. I have yet to find a reason that the screen should be switched out.
As a note - I used nothing but a plain matte screen in my original (and I mean original!) Pentax that I used from 1961 to 1976. I intensely dislike all the junk in the middle of the finder with focusing aids. With practice, you can focus just as accurately without the aids, and still be able to use your spot meter.
Every one of the three bodies I have has a grid screen of one type or another. I don't use it for "rule of thirds", but it sure is handy to keep trees and buildings standing up straight, the way they should.
