Olympus 1-11 Cross Hairs Matte Focusing Screen For Olympus OM-1, OM-2, OM-3, OM-4

This screen has a cross hairs spot surrounded by a finely ground matte area and is highly advantageous for close up and macrophotography in conjunction with Auto Bellowsand extension 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 as with the 1-12 focusing screen The meter needle indicates proper exposures but depending on the specimen. the condition of the reading must be compensated for (e.g . black dots against white background).
