Pentax's easy-use PC-series 35mm compact — fixed-focus 30mm f/4.5, oversized viewfinder, red-eye flash, AA power.
The Pentax PC-55 was a simple 35mm compact in Pentax's budget PC line, pitched at holiday and family snapshooters. Its selling point was an oversized viewfinder, marketed as especially useful for eyeglass wearers, housed in a lightweight plastic body whose lens protector doubles as the on-off switch.
The lens is a fixed-focus 30mm f/4.5, paired with automatic exposure and DX film-speed reading, plus fully automatic film loading, advance and rewind. The auto-sensor flash has a ready light and red-eye reduction, and an automatic shut-off preserves the two AA batteries that power the camera.
With no focusing to worry about and a slightly wide 30mm view, the PC-55 is a true aim-and-press camera for casual film shooters and beginners. The fixed-focus design means close subjects go soft, and the slow aperture makes it a daylight-and-flash camera, but the big viewfinder makes framing unusually easy.
Like most motorised compacts it is completely battery-dependent, so confirm it powers on, the flash charges and the shutter fires. Check the lens-protector switch for cracked plastic, watch the frame counter advance on a test wind, and inspect the AA compartment for corrosion; the low price of these cameras means faults are rarely worth repairing.
