Focusing Screen
Selector Chart
= Excellent
= Acceptable
The image is brilliant from edge to edge, but the central rangefinder, microprism or cross-hair area is dim. Focus on the surrounding matte area.
= Acceptable
Slight vignetting or moire phenomenon (in the case of the microprism) affects the screen image. But the image on film shows no traces of this.
= Acceptable
Incompatible with any lens having a maximum aperture larger than f/2.8 since this decreases the efficiency and accuracy of the screen rangefinder. The infocus image in the central spot may prove to be slightly out of focus on film. Focus on the surrounding matte area.
