The Koni-Omegaflex M is a medium format based TLR press camera system with exchangeable lens board, finders and film magazines. It was made in Japan by Konica for Simmons Omega Inc. which was a subsidiary of Berkey. See here for the serial numbers which allow to date the production of the unit.
Film
The camera shoots 6×7 cm negatives on 120 film or 220 film. There are 10 exposures with 120 film, while 220 film yields 20 exposures. Like the rest of the Koni-Omega series type cameras, the film is loaded onto the same two part film magazines, and uses a pull push knob for film advance built-into the magazine. The back has the film counter and a reminder slot for film emulsion box tabs.
Lens
Each lens board includes a lens pair and a leaf shutter made by Seiko. Aperture and shutter speeds are adjusted on the lens. The shutter speed range from B, 1 to 1/500th of a second. There are f/5.6 58mm, f/3.5 90mm, f/3.5 135mm, and f/4.5 180mm lens boards. Each lens has a minimum aperture of f/22 and has a built-in lens hood or the taking lens. Mounting each lens changes the parallax view within the finder. The lenses can be changed mid-roll with the use of a dark slide. Flash sync can use both bulbs and electronic flash with a MX selector. It uses a standard PC sync connector on each lens board.
Finder
The finder is primarily designed for eye level viewing instead of waist level common with most TLR. There is a flip open hood on the back of the camera that reveals a ground glass. Viewing in this manner is similar to a large format camera with the image upside down. This can be changed to a prism or magnifier. With the prism, images are right side up and can be used for waist level viewing.
