Fujifilm's 2006 entry-level compact — 4MP Super CCD HR, 3x zoom, xD storage, AA power.
The Fujifilm FinePix A400 was an entry-level compact announced at CES in January 2006 and on UK shelves that March, sometimes listed as the FinePix A400 Zoom. It sat at the bottom of the FinePix range alongside the higher-resolution A500, continuing the A series formula of simple AA-powered snapshot cameras.
It is built around a 4-megapixel Super CCD HR imager — the octagonal-photodiode design Fujifilm used to boost effective resolution — producing images up to 2304x1728. The lens is a 3x optical zoom, framing is via a small 1.8-inch LCD, and four scene modes (portrait, landscape, sport, night) cover the basics. Images store to xD-Picture Card or internal memory, and power comes from two AA batteries in a 93x60x27mm body.
The A400 suits buyers after the cheapest possible mid-2000s Fujifilm CCD compact, and the Super CCD sensor gives its files a slightly different character from bargain rivals. It is entirely automatic, with no manual control, and the small dim LCD makes composing in bright light a challenge — this is a nostalgia purchase, not a practical one.
The main used-market caveat is storage: it takes xD-Picture Card only, a discontinued format, so a bundled working card adds meaningful value — without one, budget for a used xD card and reader. Check the AA compartment for corrosion, the zoom for smooth extension, and the LCD for delamination. Many sell untested; price accordingly.
