Semi Minolta (I) and II
The Semi Minolta (セミ・ミノルタ) is a series of Japanese 4.5×6 folders made by Molta then by Chiyoda Kōgaku (the predecessors of Minolta). Their body is inspired by the Ikonta A or Nettar, but they are not plain copies. The prewar models were distributed by Asanuma Shōkai.

The Semi Minolta
The original model[1] has a folding finder, no body release and no cover for the red windows[2]. The finder is offset to the left and there is an accessory shoe, very slightly offset to the right. It is said to be the first 4.5×6 camera with an accessory shoe.[3] The film is wound by a key, situated at the bottom right (when holding the camera to take portrait pictures). The camera is embossed Minolta in the front leather.
This model is announced at the end of 1934: it is mentioned as soon available in the photo notes column of the December 1934 issue of Asahi Camera[4]. It is advertised in Japanese magazines from 1935 to 1938.[5] An advertisement in the July 1936 issue of Shashin Shinpō[6] shows the camera with what seems to be a folding frame finder, while another advertisement dated August 1937[7] shows a folding optical finder. The lens is a front-cell focusing Coronar 75/4.5. It is said that it was manufactured by Asahi Kōgaku (the later Pentax).[8] The shutter is a Crown, first with T, B, 5–100 speeds and later with T, B, 5–200 speeds. The price was ¥65, with an accessory rangefinder sold for extra ¥15.
The Semi Minolta II
Early version
The Semi Minolta II (called simply "Semi Minolta" in some advertisements)[9] adds a body release and a cover for the red windows. The finder and the accessory shoe are moved very slightly to the right, to leave space for the body release. The two knobs at the ends of the top plate are higher.
The Semi Minolta II is introduced at the end of 1937 and advertised from 1938 to 1943 (all versions included)[10]. An advertisement in the January 1938 issue of Shashin Shinpō[11] offers it with a Prontor II shutter (175–1, B, T) and what seems to be an f/3.5 lens, for ¥105. The accessory rangefinder is still offered, for ¥18. The following year, an advertisement in the January 1939 issue of the same magazine[12] offers two lens options:
- Coronar 75/4.5 lens and Crown B shutter (¥100)[13];
- Coronar 75/3.5 lens and Crown B shutter (¥120)[14].
Some accessories are listed too:
- accessory rangefinder (¥18);
- hood for 25mm filters, for the f/4.5 lens (¥1.50);
- hood for 30mm filters, for the f/3.5 lens (¥1.70);
- small ever ready case, for the camera only (¥5.00);
- big ever ready case, for the camera with the rangefinder (¥5.50).
Late version
The Semi Minolta II evolved during its production. The major modification occurred when the body was changed from a pressed sheet metal construction to die cast alloy. The new version is recognizable by the slightly differing body shape. It seems to have leatherette covering instead of leather. Some examples have black paint on the body edges while others have a metal finish. It is this version with die cast body that is called "Semi Minolta II" by some sources[15], while the earlier version is incorrectly called "Semi Minolta I".
Other modifications occurred, not necessarily at the same time[16], like the modification of the back opening and the disparition of the holding strap, the lens marking changed from Coronar Anastigmat Nippon to Coronar Nippon, the switch to one red window only, centred at the bottom of the back, protected by a vertically sliding cover, and the internal coupling of the finder opening button to the bed opening button.[17]
Apparently some important modification was announced in the June 1940 issue of Asahi Camera. Kokusan kamera no rekishi seems to imply that it was the disparition of the strap (presumably together with the modification of the back opening), the connection of the finder and bed opening and a modification of the spool loading parts.[18] The date of the switch to a die cast body is unknown.
An advertisement in the March 1941 issue of Shashin Bunka[19] offers two lens choices, both with a Crown B shutter (T, B, 5&dnash;200):
The accessory rangefinder is still offered for ¥18.
Later versions, from 1942, have a Crown A shutter (T, B, 1–200).
The Auto Semi Minolta
The Auto Semi Minolta is a coupled rangefinder model, released in 1937. It has a different body, largely copied from the Welta Weltur, in particular the folding struts and the focusing system are identical. The focusing is controlled by a small knob placed on the right of the folding bed, moving the whole lens and shutter assembly (unit focusing).
There is a top housing, whose shape is again inspired by the Weltur. It contains the range and the viewfinder, both sharing the same eyepiece at the right end of the camera. There are two windows, a rectangular one for the viewfinder and a round one for the rangefinder, with the name Minolta engraved both. Above the top housing there is an Auto Semi engraving, the serial number and an accessory shoe. The shutter release is on the left, above the hinge of the folding bed. The camera is also embossed Minolta in the front leather.
The Auto Semi Minolta has an automatic film advance device inspired by Plaubel products like the Roll-Op folder or the rollfilm backs of the Makina. It is placed under the right hand side of the camera, below the viewfinder. There is a big advance knob and a larger and flatter exposure counter disc, graduated from 1 to 16. The tripod screw is at the opposite end. The back is hinged to the left, with a red window protected by a vertically sliding cover, probably used to set the first exposure.
An advertisement dated November 1937[22] offers the Auto Semi Minolta with a Promar 75/3.5 lens and a Compur S shutter (T, B, 1–250), for ¥195. The camera has a holding strap and the back opening is similar to the early Semi Minolta II. In 1939[23], the shutter is a Crown II (Ⅱ型クラウン), with T, B, 1–400 speeds and a self-timer, and the price is ¥255. In 1942[24], the shutter has the same characteristics but is called Crown RS, and the back opening has been changed like on the late Semi Minolta II. The price is ¥290. The Auto Semi Minolta was among the most expensive Japanese cameras (see Japanese prices).
The Semi Minolta III
The Semi Minolta III is a postwar version of the I and II. It exists in three variants called A, B and C, with very little difference between the three.
The Semi Minolta P
The Semi Minolta P is a version with a tubular finder, released in 1951 at a time when the folding finders were beginning to be old-fashioned. It was the last folding camera made by Chiyoda.
