Olympus Focusing screen 1-11. Cross hairs-matte type. (for close-up & macro photography.)
This screen has a cross hairs spot surrounding by a finely ground matte area and is highly advantageous for close-up and macro photography in conjunction with auto bellows and extensions tubes.
For focusing in low magnification close-up photography, use the matte area, and in greater than life-size macrophotography use the double cross hairs in the same way with the 1-12 focusing screen.
The meter needle gives correct light readings , but depending on the condition of the specimen, the reading must be compensated for (e.g. black dots against white backgrounds.)
