The Petri Super (ペトリスーパー) and Petri Super V (ペトリスーパーV型) are Japanese 4.5×6 folding cameras with a coupled rangefinder, made by Kuribayashi in 1954–5.

The Petri Super

Description

The camera is a vertical folder, with the same architecture as the 4.5×6cm Weltur made before World War II by the German company Welta. In the early 1940s, Kuribayashi already released a copy of the Weltur called the Auto Semi First, and the Petri Super may be considered an updated version of the latter.

The folding struts, focusing mechanism and rangefinder coupling cam are copied on the Weltur. The camera is focused by a small knob placed on the right of the folding bed, moving the whole lens and shutter assembly (unit focusing). The main difference with the German camera and the Auto Semi First is that the distance scale is engraved on the focus knob, instead of lying under a cover inside the folding bed.

The chrome top housing containing the combined range- and viewfinder looks the same as on the former cameras, only slightly more modern with a small rectangular window for the rangefinder and no protruding frame. The eyepiece is at the right end of the camera — as seen by the photographer. There is a depth-of-field table above the top casing, marked ORIKKOR LENS and Made by Kuribayashi Camera Works Co., Ltd., and an accessory shoe on the side. The shutter release is to the left of the casing and is surrounded by a male thread to attach a distant release. The advance knob is placed next to it, at the left end of the top plate, unlike the Weltur and Auto Semi First.

The back is hinged to the left for film loading, and is retained by a sliding bar on the right. The film advance is fully manual, controlled via a single red window at the top right, protected by a vertically sliding cover. The bottom plate is chrome finished. It has film flanges on both sides, and a massive fairing for the tripod thread in the middle. There is also a small button used to release the folding bed.

The camera name Petri Super is embossed in the leather covering on the back, and also appears on a plate screwed inside the folding bed, marked Coupled Range Finder Petri Super KURIBAYASHI CAMERA WORKS CO., LTD. MADE IN TOKYO JAPAN, with Kuribayashi's round logo. The ever-ready case is made of brown leather, with the name Petri Super embossed at the front and Kuribayashi's logo embossed at the top. It has a hole at the front for the focus knob.

The regular Petri Super has a four-element Orikkor 7.5cm f/3.5 lens, whose rim is engraved KURIBAYASHI C. ORIKKOR 1:3.5 f=7.5cm No.xxxxx on a black background (with a red C. for Coated). The shutter is a Carperu (1–200, B) in #0 size with a self-timer and flash synchronization via a PC socket.

Commercial life

The Petri Super was first announced in Japanese photography magazines dated April 1954, and was advertised from June 1954 to March 1955. The camera is extensively described in the advertisement in Asahi Camera September 1954, which does not mention a price. Another advertisement in the December issue of the same magazine lists the Petri Super for ¥17,500, case included.

At the same time, Kuribayashi was also offering the Petri RF 4.5×6cm rangefinder camera for ¥5,000 less. This camera had a much more modern look and feel than the Petri Super, but had a lesser three-element lens.

Variations and actual examples

Serial numbers on the Orikkor f/3.5 lens are known in the 22xxx and 23xxx range, from 22221 to 2360x. The sequence of numbers seems specific to this lens, which was also used on the Petriflex 6×6cm TLR (in taking and viewing position). Consequently, total production of the Petri Super may be estimated at around 1,000 units.

Two variants have been identified, differing by the position of the markings on the shutter face. The first variant has the name CARPERU at the top of the fixed part and the speed scale on the rotating rim in the order 1–200, B. This variant is the most numerous, with lens numbers observed from 222xx to 231xx. The second variant has the speed scale in the reverse order (B, 200–1) at the top of the fixed part and the name CARPERU at the bottom of the rotating rim. The style of the aperture numbers also differs between the two variants. The second variant is less common, with only a few numbers observed in the 225xx and 226xx range.
