The Tanack IV-S is similar to the Type-lllS that preceded it. Unlike the Type-lllS, however, it has a black rim circling the body immediately below the top plate and above the baseplate The back is hinged. Flash synchronization sockets on the front are for M and X (at 1/25).

Later models (with serial numbers from around 76xxx on) have a film type indicator in the film rewind knob.

The first version is pictured with a Tanar 2/50 lens. The later camera is shown fitted with a Tanar 1.8/50. Although this is in the list of lenses at the back of HPR's Leica Copies book, it does not appear to be mentioned in any publications as a standard lens for any of the Tanack cameras. As far as I know, it had been with this IV-S body since new.

The top of the camera has the following inscription:

An advertisement in the December 1956 issue of Asahi Camera listed the IV-S at the following prices:

With 2.0/50  - 23800 yen.
        2.8/50  - 31700 yen.
        3.5/50  - 29100 yen.

Also listed was a W Tanar 2.8/35 lens, for 15800 yen.

The June 1957 issue of Asahi Camera also listed the IV-S, again with the option of three different lenses, and at the previous prices.
