Minolta Repo Minolta made viewfinder and rangefinder cameras. All used 35mm film, but the formats varied from full-frame to half-frame. Not all of them bore the Minolta name. Some were sold by GAF and Ansco. 1962, 410g, Rokkor PF 1.8/32
Minolta Repo II This is an "updated" version that came out one year later. It had the same features and was nearly identical in appearance. The original has a frame around the viewfinder and the selenium cell, while the updated version did not. The top plate on the original was raised slighty just above the meter, while the updated version is flat across the top with a depression for the flash shoe. 1962, 410g, Rokkor PF 1.8/32
Minolta Repo S The Repo-S was Minolta's third and final attempt to break into the lucrative, half-frame market. It appeared in 1964, and was as close as Minolta would get to "getting it right". All of the Minolta Repo cameras were small and stylish, but they were always "too little, too late". The Repo-S was no exception. This model came with a 32mm, manually-focusing (f1.8 - 16.0) lens with close focusing to 3 feet. The body is a little thinner than the earlier models, but the lens sticks out much more than on the original. This is partly due to the increased aperture. The camera still has a selenium-based match-needle exposure system, but this model dropped the unfamiliar, EV-numbering system. Now you can set the exact f-stops and shutter speeds -- much nicer -- with or without using the built-in metering system. The shutter speed range is expanded over the original model with shutter speeds of B, 1/8 - 1/500. But, although there were improvements, this version did not come with a built-in flash shoe -- two steps forward, one step back. And this was strictly a manual-exposure camera. Although other camera companies were coming out with half-frame models which included automatic-exposure options, the Repo-S lacked this feature. At least it had other convenience features -- tripod socket, PC connection and cable release socket. Film speeds from 25 - 800. A 39mm filter thread. Black and chrome versions were available. This was the last Minolta half-frame, but certainly not the end of Minolta subminis. They continued to make their popular 16mm cameras, and would go on to make some of the best 110 and disc cameras ever produced. 1964, 430g, Rokkor PF 1.8/32
Taron Chic The Taron Chic is an attractive camera due to its unusual design. The original half-frames from the 1920's were vertically-styled cameras, since the half-frame film format came from the motion picture camera, and was hortizontal across the film width. In 1959, the Olympus Pen changed this style to a vertical image so that the camera could be held horizontally, like full-frame 35mm cameras. Other manufacturers jumped on the bandwagon and made similar cameras. In 1961, the Chic did an about-face and reverted back to the original, vertically-styled half-frame camera. Shutter: Taron LX 1961, 392g, Taron 2.8/30
Mamiya Myrapid Shutter speeds 1/30 - 1/800 , Autoexposure via selenium cell, hot shoe. 1965, 444g, Tominon 1.7/32
Mamiya Hand Gun Camera It was shaped like a pistol and had a fixed-focus 45mm (f5.6-16.0) lens. It was a half-frame camera so the 45mm optic was a telephoto. So you could catch twice as many subversives per roll. No meter; just manual exposure. Speeds of 1/50 - 1/150. Built-in auto-winder to catch those commies in the act! so they are hard to find and very pricey. Also known as the Mamiya Pistol Camera, this is one of the rarest Mamiya cameras. A specialty camera (definitely not a point-and-shoot, no pun intended). Not many were made, only 250 are believed to have been made for police training purposes, and it was never sold to the public. It had a single-speed shutter (timing unknown). 1955, Sekor 1/50 - 1/150, 5.6/45
TOUGODO OPTICAL Meisupi I Camera measures; 3" tall, 4" wide and 3" in depth. 1959
TOUGODO OPTICAL Mei Half The Olympus Pen half-frame was so popular that many other companies jumped on board. Some, like Meisupi, sold cheap imitations, no doubt hurting the general image of the half-frame camera in the public's eye. This model has a fixed-focus 40mm (f8.0-16.0) lens. Speeds of B and I. Cold flash shoe with PC contact. Imitation selenium meter. Shaped almost exactly like the Pen. 1959, 238g, Sankor 8/40
TOUGODO OPTICAL Mei Half EL Little difference in the body of the Mei-Half, features are the same. 1963, 238g, Sankor 8/40
Nicnon Nicnon Binocular Camera The Ricoh Auto Half was a well made, convenient to use, half-frame camera. It was used as the base for a wide variety of cameras. In 1971, Nichiryo came out with a new approach to using the camera. This was a pair of binoculars with a Ricoh Auto Half E attached to one of the binocular lenses. The main features of the camera were the same as the Auto Half E, but some changes needed to be made. First, the speeds were increased to 1/60 - 1/250. In addition, the selenium meter and lens were removed. Instead, the optic was the 165mm (f3.5) focusing, four elements in three groups, binocular lens. This is equivalent to a 250mm telephoto on a full-frame 35mm camera. A beam splitter in one of the binoculars diverts the image to the camera. Close-focusing to 60 feet. Apertures could be set from f3.5 to 11. It was also sold as the Ricoh Teleca 240 and the Nichiryo Teflex. Shutter: 60-/250 1968, Nicnon 3.5/165
ARYCA ARYCA 72 35mm COMPACT CAMERA switchable for FULL AND HALF FRAME, pop-up flash, automatic exposure, winder incorporated. Made in Japan
Nicnon Nicnon S Same as the right half of a Nicnon. In other words, this version was a monocular instead of a binocular. But the camera part of the design was the same. This is a much more unusual variation and is highly prized by collectors. Shutter: Copal-60-/250 1968, Nicnon 3.5/165

NIKON / NIPPON KOGAKU Nikon FM2 a special order for the Norwegian Police. There may have been a few production extras, since I'm told this one was sold new by a Norwegian camera shop. I don't have the production figures, though it has been estimated at several hundred. It is one of the rarest Nikons. NO exterior half frame markings, can easily be confused with a standard FM-2 Edges of finder blacked out, showing a center vertical focusing area on a standard focusing screen Special one piece film gate, not a standard film gate modified Meter and aperture display identical with standard FM-2 Earlier FM-2 version with 1/200th sync 1983, Nikkor 1.4/50
