Variants & identification

Variant Mount Years Serial ranges Production
STX-1 Fujica X 1979 — No figure published
STX-1N Fujica X 1982 — No figure published
  1. The STX-1N's top speed is the disputed figure on this page. The Japanese Wikipedia product list says the N gained 1/1000 along with the LED meter and the new battery hatch; the STX-1N instruction manual on butkus.org keeps the STX-1's dial of B, 1/2 to 1/700 and its EV 2–17⅔ range, and describes the N only as the STX-1 with LED meter lights; two owners reviewing STX-1N bodies (Camera Go Camera, silver & silicon) both report 1/700. The 1/1000 body is the STX-2. The manual and the owners are adopted.
  2. Camera-wiki gives the STX-1's top speed as 1/750; the manual's dial reads 700 and its coupled range says 1/700, so 1/700 is used throughout.
  3. The STX-1N's date is November 1982 in the Japanese product list and 1983 in English Wikipedia's model table. Both are recorded; 1982 is used for the variant because the Japanese list gives a month.
  4. Weight and dimensions come from the multilingual STX-1 manual: 550g body alone with body cap, 690g with the 55mm f/2.2 lens including batteries and lens cap, and 133 × 86 × 88mm with that lens. No body-only dimension is printed.
  5. The Japanese product list describes the STX-1 as the ST605 II given the X mount, and arhphotographic says it shares its body with the ST605. The M42 ST605 family is on its own page; the two share a shell and not a mount.
  6. The stiff advance and the meter switch are owner reports, not published faults: a Flickr group thread on a jammed advance lever attributes it to hardened lubricant after years of storage, and the manual itself warns that the lever reaches its stop at half a turn and must not be forced. Silver & silicon notes that the release is locked while the lever is under tension, which is a design feature rather than a fault.
  7. No list price was found in any readable source. The MPF105X and MPF105XN names come from the butkus.org manual pages and the Japanese product list; what the designation was for is not stated in any source read.
How to tell them apart (expand)
  • Fujica X bayonet: 65° turn, 43.5mm flange back; M42 Fujinons need the Mount Adapter X-S
  • Mechanical shutter that fires at every speed with no battery; the two button cells run only the meter
  • Shutter speed scale visible at the left edge of the finder through a mechanical linkage
  • Hot shoe only, no PC socket; depth-of-field preview button on the front beside the mount
  • Tripod socket off-centre, to the left of the body (Random Camera Blog)

STX-1:

  • Match-needle meter: a needle at the right of the finder moving against a notched index
  • Shutter speed dial marked B, 2, 4 … 700 — 1/700 top speed, with a red X at 60
  • Battery cover on the base plate of the original pattern; the STX-1N's was redesigned
  • STX-1 on the front of the prism housing; the same body shell as the M42 ST605 II, with the X bayonet in place of the thread

STX-1N:

  • Three LEDs (+ ● −) at the right of the finder in place of the needle
  • Redesigned battery hatch
  • STX-1N on the prism housing; also badged MPF105XN

Where sources disagree

Speeds
  • B, 1/2–1/700 — the STX-1N instruction manual (butkus.org); Camera Go Camera and silver & silicon on their own STX-1N bodies
  • 1/1000 — Japanese Wikipedia's Fujifilm product list

Better supported: 1/700

The manual is the maker's and the two owners have the camera in hand. The 1/1000 figure matches the STX-2 and may have been carried across from it.

First
  • November 1982 — Japanese Wikipedia product list
  • 1983 — English Wikipedia model table

A late-1982 export release reaching the English-language market in 1983 would satisfy both.

What reviewers say

History

The STX-1 was the first Fujica with a bayonet. Fujifilm’s history puts it on export sale in August 1979, a month before the AX-1 and AX-5, and the Japanese product list explains what it was: the M42 ST605 II with the new Fujica X mount in place of the screw thread, a manual-exposure entry model to sit under the electronic AX bodies the way the ST605 had sat under the ST801. It never went on sale in Japan. Camera-wiki has it in the United States from 1979, and it also went out as the Fujica MPF105X and, through Porst in Germany, as the CR-1.

The specification is the ST605’s carried over. A mechanical, self-cocking cloth shutter from 1/2 to 1/700 second and B, with 1/60 sync at a hot shoe and no PC socket; a 0.96× pentaprism covering 90 per cent vertically and 92 horizontally, with a split-image, microprism and ground-glass screen, the shutter speed scale visible at the left edge and the meter at the right; two silicon photocells either side of the eyepiece, reading centre-weighted at full aperture through an FET circuit, ASA 25 to 3200, switched on by the half-press of the release; a depth-of-field preview button beside the mount; a 140-degree single-stroke lever. Two LR44 or SR44 cells (the manual also lists the HR44 mercury type) run the meter and nothing else. The manual gives 550g for the body with its cap and 690g with the 55mm f/2.2 lens.

The STX-1N of November 1982 replaced the needle with three LEDs — plus, dot, minus — and redesigned the battery hatch, and that is the whole of the change as its own manual describes it. The Japanese product list says it also gained a 1/1000 top speed; the STX-1N manual keeps the 1/700 dial, and two owners reviewing STX-1N bodies report 1/700, so the 1/1000 belongs to the STX-2 of 1985 and is treated here as a misattribution. The N is also badged MPF105XN. Telling the two apart takes one look through the finder: needle or LEDs.

What to check is mostly mechanical. The shutter fires at every speed with no cells in the camera, so a dead meter does not mean a dead camera, but corroded battery compartments and drifted meters are common on cameras this cheap. The advance lever reaches its stop at half a turn and the manual warns against forcing it; owners report levers that jam outright after years without use, which repairers put down to hardened lubricant, and one reviewer found the shutter speed dial stiff enough to take the camera from the eye. The release is locked while there is any pressure on the lever, which surprises people used to other cameras and is by design. Foam is the other check — the seals around the focusing screen crumble, and one reviewer’s screen had become hard to see through against the light before they were replaced. Reviewers agree on the rest: a small, sturdy, well-damped body with an excellent 50mm f/1.9 or 55mm f/2.2 Fujinon, for very little money, on a mount with very little else to put on it.
