Manufacturer description #1
LED (Light Emitting Diodes) Needle-less Metering System, Through-The-Lens Full Aperture Averaging Silver Battery Meter with Silicon Photocells.
The light is measured by Silicon photocells, which react to light tens of times faster and more accurate than conventional CdS photocells.
Exposure is indicated by seven light-emitting diodes in the viewfinder instead of the usual meter needle. The diode light can be moved several steps above normal exposure or below when special exposure effects are desired. Since the light energy reflected from the subject is converted directly into electrical energy in the form of diode light and no mechanical mechanism is used, the exposure indication is quick and meter deviation caused by shocj or mechanical failure is eliminated.
FUJINON EBC (ELectron Beam Coating) Lens
The key elements of each of the ST801's interchangeable lenses are coated with 11 layers to assure complete protection against flare and ghost images as well as producing the ultimate in color definition and picture sharpness.
The FUJICA ST801 Complete Photographic System
A wide selection of interchangeable lenses ranging all the way from 28mm wideangle to 1000mm ultratelephoto plus two zoom lenses and a complete set of carefully engineered accessories bring every picture-taking situation within easy reach of everyone.

Manufacturer description #2
Instead of the conventional CdS meter, the ST-801 continues Fuji's pioneering use of the revolutionary SILICON photocell. It allows the ST-801 to respond to light variations 10 times faster.
Instead of an electro-mechanical system, the ST-801 has SOLlD·STATE READOUT with seven light-emitting diodes (LED's), you'll see the very instant you look through the viewfinder.
Try the "DARK CORNER TEST" right now: Focus on any dark area in the store, see the bright red LED's lighting up inside the viewfinder as they respond to light variations - or the changes YOU make in f/stop or shutterspeed. Note the surprising CLARITY and BRILLlANCE of the image in the viewfinder... then judge for yourself.
Each one of these diodes, which can be seen as clearly in the dark as in the brightest sunlight, represents the difference of one f/stop from the next consecutive diode, the center diode indicating the correct exposure. If two adjacent diodes are visible at the same time, this indicates an intermediate exposure. This SOLlD-STATE readout allows you to freely and accurately CONTROL the over- or under-exposure of your picture. In addition, the fragile meter-movement, as well as the needle, are replaced by LED's and all solid-state electronics: no moving parts! Extra protection is therefore provided against meter deviations due to concussion, dust or mechanical failure.
1. FULL APERTURE METERING
No matter at what f/stop the aperture is set, it remains fully open for light-measurement, up to the moment the shutter is released.
2. SILICON PHOTOCELLS
The ST-801's photocells respond to a broader range of the light spectrum faster and more accurately than a conventional CdS cell.
3. FET (FIELD EFFECT TRANSISTOR)
The FET amplifies the light energy from the 2 silicon photocells and transmits it to the computer logic.
4. COMPUTER LOGIC
The LSI (Large Scale Integrated Circuit) of the computer's logic correlates light-intensity reflected by subject-matter with filmspeed, f/stop and shutterspeed, giving precise LED readout.
5. LIGHT EMITTING DIODES (LED's)
LED's, at a glance, show computed exposure, with full option of manual override by the photographer for any desired special effects.
MATCHED SERIES OF ESC FUJINON LENSES
Now the full range of interchangeable lenses, 28mm through 1000mm, has Fuji's multi-layer ELECTRON-BEAM-COATING which cuts flare, improves transmission and color-balance, eliminating ghost images. All feature the exclusive fixed-point, screw-in lockmount for precise seating and alignment. There are nine lenses with this technological breakthrough: 28mm f/3.5; 35mm f/2.8; 50mm f/1.4; 55mm f/1.8; 100mm f/2.8; 135mm f/3.5; 200mm f/4.5; 1000mm f/8 and 75-150mm f/4.5 Zoom. A 54-270mm f/4.5 Zoom to be announced.
Silver coated prism and aluminum mirror
By coating the surfaces of the prism with silver and using an aluminum mirror, 94% of the light passing through the lenses is reflected into the viewfinder.
The result is an unusually bright image. Focusing and checking depth-of-field are simplified even in available tight situations. A more accurate reading of the light by the photo electric cell is also assured.
Master-Control Viewfinder Shows Everything
Since the overall image is 50% brighter, COMPOSITION and FOCUSING are very fast and easy. The microprism in the center practically glows. LED readout of the solid-state electronic meter can be seen as clearly in the dark as in the brightest sunlight! Shutter-speed chosen is visible in the viewfinder, and, by depressing the Aperture-Selector Button, even DEPTH OF FIELD can visually be observed.
Precision 1/2000-sec. Shutter
New hi-efficiency focal-plane shutter with FP and X synchronization, selftimer and speeds from 1-1/2,000 sec. plus B. Never needs oiling, due to a new silicon-sintered alloy (oil-less metal) used in all moving parts. This also assures that accuracy of exposure is maintained throughout a broad temperature range from -4° to 122 deg. F.
