Vivitar XC-4

Jump to: navigation, search

The Vivitar XC-4 is an M42 mount 35mm SLR marketed by Vivitar. It is very similar to the Vivitar XC-3, apparently just lacking the self-timer countdown LED. Both were built by Cosina, most likely based on the the CSM. The camera provides TTL center-weighted metering with an LED display that indicates over and under exposure conditions. The camera's electronics are turned off when the shutter release collar is turned to the locked "L" position. The electronic self-timer provides a 10 second delay.

A half-press on the shutter release stops down the lens to shooting aperture and activates the metering display. A silver button on the front of the camera reopens the aperture for the brightest viewfinder image.

The camera can be converted to aperture-preferred automatic exposure with the addition of the Vivitar XC-A, an external motorized gadget that attaches to the top of the camera and physically turns the shutter speed knob.
