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.

Body

The basic design of the body is similar to the rangefinder Koni-Omega M model, but changes the viewfinder into a ground glass and lens.

Focusing the lens is with the large focusing knob on the right hand side of the main camera body. There is a depth of field scale printed on the body above the focus dial. There are distance scales for 90mm and 135mm lenses on the focusing barrel. Additional distance markings for 58mm and 180mm are on the face of the focusing knob.

The top of the camera has an accessory shoe. The left hand side has a lockable shutter release. It is threaded and can accept a screw-in cable release. An accessory grip can attach to the left-hand side of the body. The shutter release button is typically within reach with the grip attached. The grip can also hold the tip of a cable release head. The positioning of the grip can also be rotated. There are two tripod sockets in 1/4" and 3/8" , one on the base and another on the left hand side which is also used for the hand grip.

There are numerous interlocks on the camera involving the darkslide. The shutter release cannot be tripped and the lens cannot be removed with the darkslide inserted.

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 and shutter cocking that is built-into the magazine. The back has the film counter and a reminder slot for film emulsion box tabs. There's a film ready indicator on the backs to show that the shutter is cocked and film is advanced to an unexposed frame.

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.
