There's no "should" :) > How to be sure that the prism will be in the middle? I just cut a bit from each side at a time. The circle is not perfectly aligned with the central af confirm point, but that's not really important. Now that you mention it, and as Tomasz just said, it would be interesting to have the circle 2/3rds to one side. It would also be interesting to have two or more circles, actually... I just thought: given the original size of these screens, if you want a vertical split prism you could cut it that way--I think the shorter side of the MX screen is a bit longer than the longest side of the istD one. You could even get a not-quite horizontal split, I bet you could get ~30 degrees or so. Cutting would be more difficult though. j > 2006/2/1, Juan Buhler <[EMAIL PROTECTED]>: > > Inspired by the thread about focusing screens, last night I went ahead > > and took the screen out of my second MX (which needs a CLA anyway) > > > > The resulting viewfinder is a little bit darker than it was with the > > original screen, but the split prism makes it much easier to focus in > > low light, and focus seems to be spot on.
