Kodak's simple APS compact from 2000 — 25mm f/5.6 Ektanar lens, autofocus, flash in flip-up lens cover
The Kodak Advantix C400 was a compact autofocus camera in Kodak's Advantix line for the Advanced Photo System (APS), launched in 2000. It sat mid-pack among the fixed-lens Advantix models, adding autofocus and a distinctive flip-up lens cover that housed the built-in flash.
It used a three-element glass Kodak Ektanar 25mm f/5.6 lens with autofocus, shutter speeds of 1/90 to 1/250 second and a working aperture range of f/5.6 to f/12.6. The flash, built into the flip-up cover, reached about four metres with ISO 200 film. It accepted APS cartridges from ISO 50 to 800, offered C, H and P print-format selection in a reverse Galilean finder, ran on two AAA batteries and weighed about 170g.
The C400 was aimed at family snapshooters who wanted slightly better results than focus-free models without extra complexity. The flip-up cover protects the lens in a pocket, and autofocus gives it a real edge over cheaper Advantix bodies, though the slow lens still favours daylight or flash-range subjects.
APS film was discontinued in 2011, so the C400 can only be used with expired stock and many examples trade as display pieces. Check that the flip-up cover opens and closes properly, the flash charges, the autofocus and wind motor operate on fresh AAA cells, and the film door shuts cleanly without damage.
