![]() But what is this "focus-screen" really? Its mentioned always in reviews, as something separate from the viewfinder. Like there is some screen inside the viewfinder....strange stuff, never seen it explained. |

It's at the top of the mirror chamber and the image is projected on it. See item 5 in this diagram of an SLR:
http://en.wikipedia.org/wiki/Single-lens_reflex_camera It requires a little bit of minor surgery to get the old one out and new one in. But, they come with instructions and you can find some articles on how to do it: Here's a user review of a Hoada Split Image Focus Screen on a KM Maxxum 5D that shows you how the split image microprism image looks. It's not as nice as using a rangefinder, but this type of viewfinder screen helps if you want to do a lot of MF using an SLR type system. http://www.dyxum.com/columns/other/H...reen/gubbe.asp |

The image in the viewfinder of the srT-202 is bigger, but the image in the viewfinder of the Maxxum 5D is brighter. And I remember looking through the viewfinders of other SLRs of the day and thinking they were pretty dim. So I beleive that the srT-202 had a very bright viewfinder in its day, yet the Maxxum 5Dis brighter. I think what you're hearing is fond memories of days gone by, not objective comparisons. The Maxxum 5D has the plain ground glass focusing screen, so it was tougher to feel comfortable about getting a precise focus, but the focusing screen in the srT-202 has the split-image and microprism focusing aids that make me feel more comfortable about my ability to focus the lens MANUALLY.

Ah, interresting you guys
![]() Thanks ![]() So, this matte focusing screen, is it just some thin plane that needs to be there, because the image needs to be projected onto something before it hits the eye? If you removed it completely just letting light go on through the viewfinder you wouldn't be able to see anything? Also, what does "matte" mean? Is it an english word, or just some technical made up word? "Matte" in swedish is the same as "math", that is, a short word for mathematics. "Matt" though is the word for "not shiny", like for example you can order your prints as shiny or not shiny, or you could have some finish on your camera that is shiny or not shiny. Oh well, now that you've learned some swedish, what does this "matte" mean? Thanks again ![]() This forum is great, really nice people here it seems. |

Since it hasn't been mentioned yet, I'll add to the list:
The Olympus DSLRs have the focus confirmation feature when manually focusing but only with autofocus capable four-thirds lenses. Apparently they don't do it when it would be most useful, when using an older MF lens (via adaptor mount). |
