FUJIFILM ST801

The Fujica ST801 is a 35mm manual single-lens reflex (SLR) film camera manufactured by Fuji from 1972 to 1978. It is notable for being the first 35mm SLR to feature a viewfinder LED display for light metering, replacing the traditional needle-based system with an electronic centre-indicator-light arrangement. The camera uses an M42 screw mount, with a Fuji modification enabling open-aperture metering via a small aperture coupling tab on compatible Fujinon lenses. Its through-the-lens (TTL) metering system employs silicon photocells for greater sensitivity and faster response than earlier CdS-based systems, and the metering results are displayed with a series of seven LEDs in the viewfinder. The camera supports shutter speeds up to 1/2000 second and offers open-aperture metering with matched Fujinon lenses, though stop-down metering is required for other M42 lenses. Additional features include a very bright viewfinder and compact body design for its era, but flash synchronization is limited to 1/60 second and the aperture coupling tab on some Fujinon lenses can cause compatibility issues with other M42 cameras and adapters.
