Yashica made many half-frames with many unique features. Most notable were cameras with special quick-advance features and full-information viewfinders. Then, of course, is the Samurai series -- not the first half-frame SLR, but certainly the most advanced half-frame ever made.
(1961) Yashica's first half-frame was a vertically-styled camera, similar in appearance to the Taron Chic. It has a 28mm manually-focusing (f2.8-22) lens which is marked in meters on one side and feet on the other. Close-focuing to 3.3 feet with a filter thread of 24mm. The selenium meter (on the top of the camera) produced a recommended exposure in EVs on a readout on the front of the camera. This may sound like a strange arrangement, but it works quite well since you can take a meter reading while pointing the meter at the subject. At the same time, the lens/shutter combination is pointing up at you for easy adjustment of the shutter speed, aperture, EV setting and focusing ring. The camera has manual shutter speeds of B, 1 - 1/500. During the metering, the readout displays an EV number, after selecting an appropriate shutter speed, you can dial in the EV number. At the same time, it displays the selected f-stop. If you prefer, you can select the f-stop directly. Built in cold shoe, tripod socket, PC contact, cable release connection, and self-timer. Film speeds of 10 to 800. Parallax markings in the viewfinder. M and X flash sync. This camera has it all! The camera is called Rapide, not because it used Agfa rapid cassettes (it did not), but because it had its own, unique method of film advance. To advance the film, the wrist strap (actually it's only big enough for one finger) is "yanked".
It's exactly the same as Yashica Rapide, but with a different name. It is more often seen as the Rapide.
(1962) Here is a horse of a differnt color. It is a vertically-styled camera that looks similar to an 8mm movie camera -- only wider. It had a 28mm, manually-focusing (f2.8-22) lens with idiot symbols instead of feet/meter distance marks. The exposure system is metered-manual. First, the film speed (10 to 800) is dialed into the selenium meter. When the camera is pointed at the subject the meter displays an EV number in a window on top of the camera. This number is then dialed into an "exposure" ring on the lens. The shutter speed (1/30 - 1/250, plus B) is set when the film speed is dialed in, and then the aperture fine-tunes the exposure when the EV number (8-17) is dialed in. The f-stops (f2.8-22) are displayed on the exposure ring, but they are very hard to see. For flash use, the "exposure" ring around the lens is set to the "FLASH" mark and a separate lever allows you to select the desired f-stop. The shutter is set to 1/30 for flash use. The exposure ring also has a B setting which allows manually setting the f-stop for long exposures. This is the same set-up that the original Canon Demi half-frame used. There are no manual settings of the shutter speed, except B and FLASH (1/30). The Sequelle also sported a unique battery-powered, built-in motor drive for advancing the film. There is no way to advance the film manually. In order to use the camera you'll need the motor-drive battery holder which takes three AA batteries and fits into the back of the camera where film normally goes. You'll also need the special film take-up spool, which slides into the side of the camera with the film. Viewing is through a pop-up sports finder. It has a tripod socket, cable release socket and PC contact built in. No built-in flash shoe. Apparently a rare version with a 45mm (f4.5) lens was made for police use, although in all other respects it is the same camera.
similar to the Mimy, but with a focusing lens.
In 1965, Yashica modified the original Half 17 and created a model called the YASHICA HALF 17 RAPID since it uses Agfa Rapid cassettes. It is nearly identical to the Half 17 with the same lens and most camera features, but the body is about a quarter of an inch longer to accomodate the RAPID cassettes. The camera does not have the film speed dial of the original since it does not need it -- the tab on the RAPID cassette sets the film speed. The camera no longer sets the exposure automatically, for some unknown reason -- sort of defeating the purpose of a "rapid" camera. The camera has the same selenium meter as the original, but in this model it is a match-needle meter. The shutter speed is no longer displayed in the viewfinder -- just a match needle system. To operate, you turn the EV ring around the lens until the needle in the viewfinder matches the notch on the scale. The EV ring manually changes the f-stop and shutter speed in combination -- from f1.7 at 1/30 to f16 at 1/800. The EV ring actually has two scales. In match-needle mode, the scale is marked in EV numbers which is also useable with many hand-held meters. For flash purposes, the aperture can be set manually -- on the other end of the scale -- and the shutter fixed at 1/30. "B" can also be selected on the EV scale (that's right), which fixes the aperture at f1.7 -- just like in the original. The viewfinder also shows distance and parallax information. Camera included cold shoe with PC contact, self-timer; tripod socket and cable release connection. At least this model kept the "upside down", thumb-operated film-advance system.
