The Nikon Type B2 is an interchangeable focusing screen for the Nikon FM2, FE2 and FA. It features a central fine-ground matte focusing spot and a reference circle corresponding to the centre-weighted metering area. It provides an uncluttered view without a split-image or microprism focusing aid, making it particularly suitable for close-up photography, copy work and telephoto lenses.
This original Nikon accessory offers an alternative to the standard focusing screen and is useful for photographers who prefer focusing on a matte surface.
