The Cosina Hi-Lite EC doesn't profit from the Zeiss lens's electric function image by Uwe Kulick (Image rights) |
The Hi-Lite EC is an innovative SLR from Cosina introduced in 1972.[1] It is among the few models ever to offer aperture-priority autoexposure using plain-vanilla M42 screwmount lenses.
The shutter release plunger has a long travel, and partway through its stroke the lens stops down to shooting aperture and the metering circuit activates.[2] Fast-acting silicon blue photocells are able to read the scene illumination in the split-second before the user fully depresses the release button, and indicate the resulting shutter speed with a needle in the viewfinder. However there is no easy exposure compensation possible, aside from "lying" to the camera about the film's ASA/ISO speed. In this case the user can manually select a shutter speed different from the one indicated by the meter needle.
To return the viewfinder to its brightest image, a silver button on the front of the camera resets the lens to its widest aperture and deactivates the meter.
The autoexposure system is enabled with an electronically-timed vertically-traveling shutter which ranges steplessly from 2 to 1/2000 seconds. Flash sync is at 1/125th of a second. The shutter is dependent on power from the somewhat uncommon 6 volt silver-oxide battery, loaded through a cap on the back of the body; and there is a battery-check button to confirm the viewfinder needle reaches to or above the index mark in the center of the shutter-speed scale.
ASA or DIN are set using a collar below the shutter-speed dial. The collar around the rewind crank is simply a film-type reminder for the user, but does not connect to the meter system. There is a mechanical self-timer lever on the front of the body.
McKeown notes a Cosina Hi-Lite EC II adding a spot-metering option in addition to the averaging pattern, but we have not found it.[3]
