Olympus Focusing Screen 1-12
Cross hairs-clear field type for photomicrography & greater than life size macrophotography.
This transparent screen offers the photographer focusing with an unusually bright finder image. Ideal for macrophotography of 1:1 or over, and for photomicrography.
To focus, first correct your diopter using a dioptric correction lens or Varimagni Finder so that each line of the double cross hairs can be seen clearly and separately. Then bring the specimen into focus.
The meter needle gives correct light readings.
Like new, comes with original box.
