The Halma Flex and Halma Auto are Japanese 6×6 TLR cameras, perhaps made around 1960 by a company called Hara, successor of Lustre.[1] The Prinz Flex and Prinz Auto are name variants of the Halma Flex.

Common features

The Halma Flex and its Prinz name variants are regular copies of the Rolleicord. The front plate moves back and forth for focusing. The film advance knob is on the photographer's right and the focus knob is on the left. The release button is placed at the bottom of the front standard, on the photographer's right, and the synch post is buried in the front plate on the opposite side. It seems that all the models have a sportsfinder in the viewing hood and an accessory shoe. The Halma Auto has similar features with a crank advance.

Advertised versions

The only advertisement for the Halma 6×6 TLR observed so far was published in Camerart (a Japanese magazine published in English language), perhaps in 1960.[2] It was inserted by Tohko Co., Ltd., certainly the distributor of the camera, and also presents the Halma 44 and the Owla Stereo. Four versions of the Halma Flex are listed, all of them having a synchronized shutter of the "Prontor type" (B, 1–300, self-timer):

  • Halma Flex I: red window film advance, push-on filters;
  • Halma Flex IB: red window film advance, bayonet filters;
  • Halma Flex II: semi-automatic film advance, push-on filters;
  • Halma Flex IIB: semi-automatic film advance, bayonet filters.

The description says that the exposure counter of the semi-automatic models is automatically reset to "S" when the back is opened.

Evolution of the Halma Flex

The Halma Flex is known with three types of nameplate, all of them inscribed HalmaFlex. Type 1 is oval and has a small serial number, type 2 is almost rectangular and has a serial number too, type 3 is almost oval and has no serial number.

Today, the Halma Flex is surprisingly common in South American online auctions, from Argentina or Brazil; this is perhaps an indication that the camera was exported to these two countries. (A transaction for a Halma Auto has been recorded in Argentina too.)

Type 1 nameplate

Type 1 nameplate has been observed on a few cameras only. They have an accessory shoe on the photographer's right. The strap lugs are identical to those of the last Lustreflex models. The focus knob is surrounded by a silver depth-of-field scale. The taking lens is a Halmar Anastigmat 8cm f/3.5 and the viewing lens is a View Halmar 8cm f/3.2 of slightly larger aperture.

One example has serial no.31234 and corresponds to the specifications for the Halma Flex I; it has a simple shutter casing with a black front plate.[3] That pictured on the right has serial no.31802 and corresponds to a Halma Flex IB; its shutter casing is similar but has a silver front plate. Further cameras correspond to the Halma Flex IIB.[4]

Type 2 nameplate

Most of the Halma Flex cameras have type 2 nameplate and a serial number in the 4xxxx range. The accessory shoe, strap lugs and depth-of-field scale are similar to those fitting earlier examples.

The manual examples have a round red window in the back, protected by a vertically sliding cover. Examples of the model I have a black shutter plate; at least one of them is known with gray leatherette covering.[5]

The semi-automatic examples have a round exposure counter window above the accessory shoe, and no red window in the back. The position of the first exposure is certainly set by aligning the start mark of the leader paper with a mark inside the body. Some examples may have the same simple shutter casing as on earlier cameras, with a silver front plate. Others, such as that pictured above, have a Copal-MXV shutter under a more elaborate black casing.[6] The Halmar Anastigmat and View Halmar lenses were replaced at some time by Halmar and Viewer Halmar 75mm f/3.5, as is visible on the above camera.

Type 3 nameplate

Later examples have type 3 nameplate. They are similar to the camera pictured in the 1960 advertisement, and many minor features differ from the previous examples. There are new shorter strap lugs, a different back latch engraved JAPAN, and a different focus knob with a film reminder and a black depth-of-field scale. The accessory shoe has moved to a new location above the focus knob. The shutter release is bigger and contains a cable release thread. It seems that the camera now has 8.0cm f/3.5 lenses, and at least one source reports a pair of Tri-Lausar by Tomioka.[7]

The Prinz Flex and Prinz Auto

The Prinz Flex and Prinz Auto were distributed by the British company Dixons around 1960.[8]

The Prinz Flex is a name variant of the Halma Flex I. The nameplate reads PRINZ FLEX and has a four-digit serial number inscribed in small characters above. All the examples observed so far have grey leatherette covering; except for the nameplate, they are similar to the grey Halma Flex I (type 2) described above.[9] They have Halmar Anastigmat and View Halmar lenses. The body edges and the nameplate are painted in a dark grey colour, but the borders of the front standard and viewing hood are black. The focus knob is engraved in metres (in red) and feet (in black).

The Prinz Auto is a name variant of the Halma Flex IIB (type 2) with Copal-MXV shutter. It normally has a Tri-Lausar Anastigmat taking lens and a Tri-Lausar Viewer viewing lens, supplied by Tomioka, but it is said that the Prinz Auto was also advertised with Halmar lenses.[10] There are some minor differences from the Halma Flex with Copal: the synch post is placed at the top of the front standard, the M/X selector (with a yellow dot) is not placed the same, the aperture scale has red numbers and runs in the reverse direction (with 3.5 at the bottom). The name PRINZ AUTO is inscribed on a stepped nameplate, with the four-digit serial number engraved in small characters above. The right hand strap lug is engraved JAPAN and the accessory shoe is engraved H.S, probably for Hara Seisakusho.

The Prinz Flex and Prinz Auto probably shared a common sequence of serial numbers; those confirmed so far range from 1938 to 3171.[11] The ever-ready case for both cameras is similar except for the cut-out at the rear for the red window. It is made of brown leather and has a triangular PRINZ logo.

The Halma Auto

The Halma Auto is a crank advance version of the Halma Flex IIB. It was listed in the 1960 advertisement cited above,[2] where the film advance is described as "fully automatic". It is not known if this corresponds to automatic film loading as on a Rolleiflex, or simply to the faster crank advance, which cocks the shutter at the same time. The advertisement also mentions the ability to make double exposures when required.

The Halma Auto is only known with the type 3 nameplate and the newer strap lugs and back latch, whether in the advertising picture or in the only other picture observed so far.[12] The position of the exposure counter window is higher than on the regular Halma Flex, this feature is perhaps shared with the other "type 3" Halma Flex.
