Hmmm, another solution, which works well for me, is to get glasses
with the camera-focus eye side corrected for the camera VF optics.
A 24mm is EASY to focus, and 16mm, 15mm (f5.6!), and 8mm lenses aren't
hard, either, using the matte B and E screens in the FE/FM/FA. I have
never encountered an instance when a split-image, uh, "focusing aid",
didn't just get in the way on an otherwise clear and sharp matte VF
screen (at least near the center).
Hope This Helps
