The Pentax Program Plus (1984–1989) — sold as the P30 in many markets and the A3000 in others — is a polycarbonate-bodied 35mm SLR positioned between Pentax's ME-series compact bodies and the more capable Super Program (Program A). It targets photographers who wanted flexible exposure control beyond simple program AE without paying for a full manual-first body.

About this camera
Pentax's mid-1980s consumer SLR that delivered program AE, aperture priority, and full manual control in a lightweight K-mount body — a practical all-rounder for the photographer who wanted options without the bulk or cost of the Super Program.

Pentax introduced the Program Plus in 1984 as part of a broad push into program-mode photography. The Super Program (Program A), launched the same year, sat above it with a wider shutter range (down to 1s), depth-of-field AE mode, and a brighter finder. The Program Plus traded some of those features for a lower price and a slightly lighter, more consumer-friendly body.
In several markets it carried the designation P30; in Japan and some Asian markets it was the A3000. A later variant, the P30n/P30t, added DX coding and minor improvements through the late 1980s. The line wound down as Pentax shifted to the SFX/SF series of autofocus bodies.
The Program Plus represents the high-water mark of the mid-1980s manual-focus consumer SLR: fully electronic, offering program convenience alongside aperture-priority precision and complete manual control, compatible with the extensive K-mount lens ecosystem. AA batteries make it practically convenient; the viewfinder's 0.87× magnification provides a comfortable, bright view.
Today it is one of the most affordable K-mount film bodies available — frequently found for under $30 — that still provides full control alongside SMC Pentax-A lenses.
Pentax K mount. Full program AE requires SMC Pentax-A series lenses (aperture ring has A position). SMC Pentax-M lenses work in Av and M modes. Older SMC Takumar M42 lenses work with an M42→K adapter in stop-down metering mode. Good pairings: SMC Pentax-A 50/1.7, SMC Pentax-M 50/1.4, SMC Pentax-A 35-70/3.5-4.5 zoom. Dedicated AF-integrated flash via hot shoe (no TTL OTF flash — center-weighted with flash).
