6x Focusing Finder DW-2 Designed initially for parallax focusing with cross-hair focusing screens, it magnifies the entire viewing field by 6 times. But the 6X focusing finder can also be used with split-image or microprism screens for close-ups and macrophotography, astrophotography and other applications requiring extremely fine focusing. Its optical construction, similar to a fine lens, produces an exceptionally bright viewing image. The eyepeice may be adjusted from -5 to +3 diopters.
