When using the split-image rangefinder, you will see inlhe centre of ihe imoge field o circulor oreo horizon-tolly divided into two holf-circles (definition indi-cotor). When ihe lens is not shorply focused, o ver-iicol line which posses lhrough these two holf-circleswill oppeor broken ond...

The split-imoge rongefinder circle is surrounded by o micro roster ring, which serves the some functionos o ground-gloss screen. The outlines of o subiect will oppeor unshorp in this ring until ihe lens is cor-recily focused (Fig. 3). This micro roster ring should be used for focusing on detoiled siruclures ond pollernsor for copying, etc., ond for subiecls which hove no distinct stroight Iines.The remoining imoge oreo outside the centrol rings is olwoys bright ond shorp but connoi be used forfocusing....
