• 38 MANUAL FOCUS The ME-F comes equipped with a split-image/microprism focusing screen which provides a split-image center spot surrounded by a microprism collar on a matte field. For situations where the TTL electronic focusing system does not apply you can focus manually using all three areas of the focusing screen. To focus with the split-image center spot: simply turn the lens focusing ring until the broken image in the center spot of the viewfinder aligns as one. To focus with the microprism collar: When using the microprism collar surrounding the center spot, rotate the lens focusing ring until the "shimmering" effect in the collar area seems to disappear. The matte field: This is quite handy for focusing with long telephoto lenses having small apertures to which electronic focusing doesn't apply. To focus, turn the focusing ring of the lens until the image on the matte field appears sharp and crisp.
