The '''Vivitar 450/SLD''' is a [[Cosina]]-made [[M42]] mount, [[35mm]] [[SLR]], marketed by [[Vivitar]]. It is likely based on the [[Cosina Hi-Lite 405 | Hi-Lite 405]].

It has a mechanical metal shutter with speeds from 1 to 1/1000 of a sec and a B mode. Film of 25 to 3200 ASA can be used.

[[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 450/SLD is distinguished from its contemporary the [[Vivitar 420/SL]] by offering a spot metering option, selectable using the collar under the film rewind crank.
