The Vivitar Series 1 440PZ is a 35mm film point-and-shoot compact carrying Vivitar's Series 1 branding, a name the company used from the 1970s onward for products positioned above its standard consumer line, applied here to a zoom compact from the film-camera era.
Specific technical documentation for the 440PZ could not be confirmed. Its "PZ" designation indicates a power zoom lens, consistent with other Vivitar Series 1 point-and-shoot compacts of the period, which typically offered autofocus, built-in flash, DX film speed sensing and automatic film advance and rewind.
As a film compact rather than a lens or SLR, the 440PZ traded on Vivitar's Series 1 name recognition while competing in the crowded 1990s zoom-compact market against similar autofocus models from Canon, Pentax and Olympus.
Used examples occasionally appear at car boot sales and online. Buyers should check the battery compartment for leakage, test the zoom and shutter operation, and inspect the lens and light seals before loading film.
