Canon's touchscreen budget compact — 2012 A-series with 16MP CCD, stabilised 5x zoom and 720p video
The PowerShot A3400 IS was a 2012 model in Canon's slim A3xxx budget line, notable as the variant that added a touchscreen to the range. It slotted between the A2400 IS and the Wi-Fi-equipped A3500 IS in Canon's entry-level compact lineup of that year.
Specification centres on a 16-megapixel 1/2.3-inch CCD, a stabilised 28-140mm-equivalent f/2.8-6.9 5x zoom and Canon's DIGIC 4 processor. The 3.0-inch 230,400-dot LCD is touch-sensitive, video records at 720p HD, cards are SD, SDHC or SDXC, and power comes from a rechargeable lithium-ion pack rather than AAs.
It is a pure point-and-shoot: automatic scene selection, touch focus and no manual exposure modes. That makes it a low-cost everyday or first camera, and its late-CCD sensor places it among the last generation of CCD compacts, which some buyers seek out for the colour rendering.
Check the touchscreen responds across its whole surface, since it is the model's defining feature, and confirm the stabiliser and zoom operate quietly. It needs its proprietary lithium-ion battery and charger — verify they are included, as replacements are cheap but the camera will not run without them. SD-family cards remain current, so storage is no obstacle.
