"When focusing with these screens, while looking through the viewfinder, place the subject you want to focus on in the central cross hairs, and focus the lens. When the subject does not come off the central cross hairs even if you have moved your eyes slightly to the right or left, your subject is then in focus. The SD-11 is suited for astrophotography and photomicrography, and if used for other purposes, or depending on the telescope or microscope to be used with, the corners of the frame may be darkened."

If your purpose is to use your "normal" lenses (even the not so normal 50-250/4) and not a telescope I should warn you: not use one of the new (and expensive) screens for the LX (the -60/-69 ones). They won't fit your needs and you'll be disappointed. Go for a screen designed for "general purpose" (the SC-21, SA-21 et simila). Have a look at http://www.euronet.nl/~pimr/fscrntab.html for an idea of the compatibilty of the screens with the various lenses. > When I will get the mirror lens I figured I will need to get a screen that > was designed for such lenses.

(did you ever consider > contact lenses? Doing photography now I tahnk god several times I do not > have to wear glasses, though the day will come I am certain) I would have a hard time trying to take a photo without glasses: I press the camera with a certain effort on my right eye and my nose to hold it steady (I usually shot handheld even with 1/8, 1/4s). If I didn't wear glasses I'd change the shape of my nose and would need to clean up the eyepiece after every shot. This way I only have to change the right lens of my glasses on a regular basis (you cannot imagine how can a camera induce scratches on glass...). > > When I mounted the SE-60 I must admit I couldn't believe to my > > eyes.

I can suggest the SE-60 coupled with the SC-21 or SA-21. The last two were my most used screens on my LXs before I could put the hands on the SC-69 (do not use this one in the MX for normal shooting!). > Boy, I should just quit photography, or get a rangefinder so I don't have > to deal with this stuff. :))) (Just kidding I hope everyone realizes) > This is what a scratched up screen did to me, I would have never > considered changing screens if my MX screen would not be scratched up :)) Screens get scratched.
