The Vivitar 400/SL was a Cosina-made M42 mount, 35mm SLR, marketed by Vivitar in the 1970s.
Stop down metering is activated by pressing the shutter release halfway and adjusting settings until the needle at the viewfinder edge is centered in a small bracket. The viewfinder can be returned to maximum brightness by pressing the aperture re-open button on the front of the camera body. The meter circuit is designed to be powered by one 1.35v #675 mercury battery.
The otherwise-similar Vivitar 420/SL adds a battery check and a locking collar around the shutter release.
