The 4000S is one of many [[SLR]]s from [[Cosina]] accepting [[42mm screw lenses]] and offering [[stop down]] metering. This is a particularly no-frills model, although it does include a [[hot shoe]] and a self timer. Compared to the similar [[Cosina Hi-Lite 402 | Hi-Lite 402]] this model omits the battery check, shutter-release lock, and any film-reminder aids.

A half-press of the shutter release stops down the lens to the selected aperture and activates the meter, which is powered by one 1.35v [[mercury cells | mercury button cell]]. The user then adjusts exposure settings to center a needle in the bracket at the right edge of the viewfinder. A chrome button on the front of the camera can reopen the aperture again for the brightest image for focusing and composing.

This appears to be the model rebranded by [[Vivitar | Ponder & Best]] as the [[Vivitar 400/SL]].
