The Samsung ES78 is a budget point-and-shoot compact from 2011, part of Samsung's entry-level ES series (sold in the UK through mainstream chains like Currys) aimed at simple, no-fuss snapshot photography.
It is built around a 14.2-megapixel CCD sensor with a 5x optical zoom lens, a 2.4-inch LCD, built-in flash, face detection and Samsung's beginner-friendly Smart Auto scene selection, with standard-definition-plus video and SD card storage — deliberately basic, light and cheap.
Its significance today is entirely down to the Y2K-adjacent digicam revival: the ES78 is exactly the kind of unassuming CCD compact whose slightly filmic colour rendering and lo-fi flash aesthetic has found a second life with younger UK buyers, driving its surprisingly robust 13-listing presence for what was a sub-£100 camera new.
UK used-buying checks: keep the price honest — this was entry-level, so mid-double-figures is the right zone even boxed; check the battery situation first since Samsung's small compacts of this era used the BP70A, which is thankfully cheap and current; cycle the zoom and flash a few times as these cost-focused mechanisms are the usual failure points; look for corrosion in the battery/SD compartment; and prefer boxed examples with the charger, because on a camera this cheap the accessories are a large fraction of the value.
