The Cortina 500 is a viewfinder camera for 35mm film. It was made in Hong Kong, originally as Halina 500 by Haking. It's almost a clone of the Olympus Trip 35. It was launched in 1972.
The Cortina has an Anastigmat Cortina 1:2.8 F=40mm lens, the Halina 500 a Halinar 1:2.8 F=40mm.
The CdS-metering controls the aperture (f2.8 to f22) and shutter (from 1/40-1/200 sec) in a similar fashion to the Olympus Trip 35. The shutter release will be locked when light is too dim and a red flag will appear in the viewfinder. The CdS metering system requires a now defunct PX625 mercury cell but modern alternatives do exist. As the CdS sensor sits on the lens mount it adapts to any filter.
Like the Olympus Trip 35 the Camera has an Automode mode (A) which the user sets on a ring around the lens or sets the aperture for flash use. If selecting the aperture with an operational CdS metering the opeing of the aperture is also dependant on the light falling on the CdS system like the Olympus Trip 35. Without the battery unlike the Olympus Trip 35, the camera functions as a fully manual camera with shutter at the lower speed.
Focus is by a 4 zone focus system. Unlike the Olympus focus is not visable from the viewfinder.
Shutter button is front mounted but there is a screw point for cable release on the top of the Camera. Film advance is by thumbwheel and a standard tripod mount is on the base. There is a hotshoe and a sync cable point for flash
Likely this was replaced by the Halina 35-600 (also known as Prinz Saturn 35 auto)
