Type K: Combination of Type A and J screens. Matte/Fresnel field with 3mm¢ split-image rangefinder spot
surrounded by 1mm-wide microprism doughnut. Rapid and accurate focusing for subjects with both straight lines
and ill-defined contours. Suitable for general photography.
Type L: Same as Type A screen but with split-image rangefinder line at a 45
°
angle. Best for subjects with
horizontal lines.
Type M: Fine-ground Fresnel field with 5.5mm¢ clear spot and double cross hair for use in parallax focusing on
aerial image, 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.
Type P: Same as Type K but with split/image rangefinder line at a 45
°
angle and etched horizontal and vertical
lines as an aid to compositon. Rapid and accurate focusing for subject with horizontal or vertical lines or
ill-defined contours. Suitable for general photography.
Type R: Same as Type A but with rangefinder prisms of sloping surfaces at a smaller angle and horizontal area
vertical lines to aid proper composition. Works best with lenses having maximum apertures from f/3.5 to f/5.6.
Type T: Matte/Fresnel field with spit image rangefinder, 12mm¢ reference circle, and horizontal and vertical
lines. Used when preparing slides for TV broadcasts. Dotted lines indicate standard TV screen format. Solid
outline shows sale action area whereas broken lines indicate "safe title" area.
Type U: Matte/Fresnel field with 3mm¢ fine-ground matte focusing spot and 12mm¢ reference circle. Utilizes
the same matte field as Type B, but with lenses longer than 100mm the image in the viewfinder is easier to see.
