The Samsung ES73 is an entry-level point-and-shoot from Samsung's ES range, launched in 2010 alongside the closely related ES74, with which it shares a single instruction manual. It was pitched as a simple, affordable second camera.
It uses a small CCD sensor in the roughly 14-megapixel class typical of Samsung's 2010 ES-series, behind a 5x optical zoom lens starting around 27mm equivalent. The rear LCD is a fixed 2.7-inch screen without touch control, images save to SD/SDHC cards, and the camera runs on AA batteries rather than a proprietary pack.
Where higher-tier Samsung compacts of the period added touchscreens and Wi-Fi, the ES73 kept things simple with physical buttons, prioritising low cost and easy battery sourcing over features rather than a distinctive rendering character.
These sell cheaply secondhand as basic backup cameras. Check the battery compartment for corrosion from leaked AA cells, that the zoom lens extends without catching, and that the LCD is free of dead pixels.
