Thanks everyone for all the tip about which screen to use.

I'm not sure exactly what you mean here Brian. I used these before and not
found them very suitable with my Sigma 600/8. How can one focus with only
1/2 of the split image? Isn't both halves needed so that focus can be
obtained by aligning them?

Very much appreciated thank you.

Thanks Hans, that's what I wanted to know. Do you think a combination of
Sigma 600/8 + 2xA Zuiko converter + 2-4 screen would work? Probably better
than with my present 2-13 screen at least I would think. The central
focussing aids are hopelessly dark for most of the time, unless my eye is
exactly centered in the viewfinder.

A longer focal length reached with the help of a converter apparently
doesn't always necessarily mean that the screen will darken. Well, that's
hopeful!

Yes, I remember how bright everything looked in the viewfinder after having
installed the new 2-13 screen in my OM-2SP a couple of years ago. If I only
had been foresighted enough to realize that I would mostly use my OM-2SP for
300 and 600 mm super tele photography I would have bought the 2-4 instead.
Btw, if anyone wonders what_I_use for normal photography it is an iS-3000
with 28, 300 and macro converters.

Yes, I think I'll buy the 2-4. I know this problem from experience when I
bought the 2-13. Btw Ulf, I think it was from you that I learned that the
2-# series screens could be bought for the same price as the 1-# series,
i.e. if you are persuasive enough. The problem is that the photo store in
Norrköping where I bought the 2-13 screen now hardly have any contacts any
longer with Olympus Sweden, at least this was what they told the last time I
visited them. To buy directly from Olympus Sweden you have to have a
business or a firm I think. Maybe one of the larger Sw mail order stores
like Scandinavian Photo or Cyberphoto can help me though.
