Petri GX-1

The Petri GX-1 is a reflex camera. The 35mm camera was built by Cosina and also offered under the name “Cosina CT-1A”.

The lenses of the Petri GX-1 are interchangeable. This is made possible by the Pentax K bayonet. You have to focus the lens by hand. The 35 mm camera does not have an autofocus function.

The 35 mm camera has a built-in light meter. It can be used with films from ISO 25 to ISO 1600. Exposure is determined by SLR when measured by the lens (TTL). The shutter speed and aperture can be selected by the photographer.

The camera comes with a Bulb setting option. In this mode, the shutter will open as long as the shutter release button is pressed. Hot shoe flashes can be used with the camera. There is also a PC flash socket.
