Nikon description: Fine ground Fresnel field with 5mm diameter clear spot and cross-hair for use in parallax focussing on aerial images, plus millimeter scales for calculation of individual magnification of objects or for measuring objects. Brilliant image in dim light. Suitable for close-ups, photomicrography, and other high-magnification applications. Again, get the 6x finder before considering this one.
