ST705 [1976 - 1978]
You could be forgiven for assuming that the ST705 was the successor to the ST701, but it was actually a new design that employed open aperture TTL metering. The date of launch is a little unclear, but despite being a companion to the ST605, the ST705 appears to have been introduced later in the year, perhaps around the turn of the 76/77 year.
A DOF preview button also allowed the camera to perform stop-down metering, and thus use non-Fujinon lenses. It was generally better specified than the companion ST605: for example, it had a lens lock, and a metal rewind knob.
Similarly to the ST605, the ST705 had an unusual top shutter speed - 1/1500th sec - a half stop value. It was generally bundled with a slightly better lens; either a 50mm f/1.4 (7 elements in 6 groups), or a 55mm f/1.8 (6 elements in 4 groups).
According to an advertisement in a January 1977 edition of Practical Photography, the ST705 with an f1.8 lens was priced at around £143, which was more expensive than the Pentax K1000 with an f/2 lens, offered by the same retailer for £130. The ST705 was produced in chrome and black finishes.

ST705w [1978 - 1980#]
My ST705w fitted with a Fujinon-Z 43-75mm zoom lens. I have not included a photo of an ST705, because it looks so similar.
In 1978, the ST705 was replaced by the ST705w; where "w" stood for winder, indicating that the power winder developed for the Fujica AZ-1 could be attached to the camera. Other new features included a viewfinder shutter speed pointer (as found on the ST605n upgrade), plus a safety lock on the shutter release, and restyled wind-arm. The camera was sold with the same two lens options as the ST705.
According to an advertisement in a May 1979 edition of Amateur Photographer, the ST705w with an f1.8 lens was priced at around £160, which was about £30 less than the new Pentax ME or MX (with an f/1.7 lens).
A copy of the instruction manual can be found at Kim's Fujica website.
Neither of the ST705s are mentioned in Fujifilm's Japanese Corporate website account of the company's history. I have been puzzled as to why Fuji made the ST705w alongside the very similarly specified ST605 Mark II, but maybe the ST705w was made for export only? Clearly, Fuji's market focus was about to shift again, since much of their 1977 effort (and marketing) had gone into development and promotion of the AZ-1, with its greater reliance on electronics.
