Nikon F-801S Focusing Screen Type "E" Original Box

The Nikon F-801S is a 35mm autofocus and autoexposure single-lens reflex (SLR) film camera that was introduced by Nikon in 1988. It was known as the Nikon N8008 in the United States. The camera was part of Nikon's mid-range lineup and was designed to offer advanced features in a user-friendly package.

Regarding the focusing screen, the Nikon F-801S typically came with a Type E focusing screen. The focusing screen is an important component in an SLR camera as it aids in manual focusing by providing a clear and bright image in the viewfinder. The Type E focusing screen is a matte field with a central split-image/microprism collar surrounded by a matte field.

Here are some key features and characteristics of the Type E focusing screen:

1. Matte Field: The majority of the screen is matte, providing a smooth and even surface for composing and focusing.

2. Split-Image/Microprism Collar: In the center of the matte field, there is a split-image/microprism collar. This portion assists in manual focusing by providing a visual indication of when the image is in focus. When you turn the focusing ring on the lens, the split image aligns, or the microprism pattern appears to "snap" into focus.

3. Compatibility: The Type E focusing screen is designed for general-purpose use and is compatible with a wide range of lenses. It is suitable for various photography applications, including portraits, landscapes, and more.
