The Fujica ST801 is a manual SLR 35mm film camera made by Fuji between 1972 and 1978. It was the first 35mm SLR to use viewfinder LEDs, replacing the traditional centre-the-needle meter display with a centre-the-indicator-light system. This electronic light metering system was developed to eliminate mechanical failure, and needle deviation caused by shocks.
- M42 mount. Fuji created a modification to the standard 42mm screw mount, adding a very small tab on the back of the aperture ring to communicate with the body's light meter to permit open-aperture metering. Unfortunately, M42 Fujinon lenses are sometimes found to have had their aperture coupling tab filed off. While unmodified lenses do fit many M42-mount camera bodies, some lens flanges (or lens adapters) are wide enough in diameter so that the aperture tab interferes with mounting the lens.
- TTL average light meter, with LEDs
- Open-aperture metering using silicon photocells, more sensitive and faster-responding than CdS cells
- Shutter speeds up to 1/2000 s
Pros and Cons
- Very bright viewfinder (probably brightest finder on an M42 body, save the Bessaflex)
- Light meter uses 7 LEDs which are visible in adverse light conditions, and indicate approximately 3 stops of over- and under-exposure. Fractional stops are indicated by adjacent pairs of LEDs being illuminated.
- Open-aperture metering when used with matching Fujinon M42 lenses
- Very compact for its time.
- Stop-down metering has to be used with non-Fujinon lenses. (Open-aperture metering is also available with TX-system lenses from Vivitar or Tamron Adaptall-2 lenses, if a Fujica-ST-specific M42 mount adapter is obtained.)
- Only 1/60th sec flash synchronisation
