Focusing Screen B (Split-Image)
Matte/Fresnel field with split-image rangefinder spot in center of screen. Ideal for use with 15mm fish-eye, super wide-angle, and wide-angle lenses and for subjects having straight lines. Unsuitable for close-up and macro-photography and for use with lenses having small maximum apertures or requiring stopped-down metering, because one-half of rangefinder darkens.
