Canon's tiniest Digital IXUS — fixed 39mm f/2.8 lens, 4MP CCD, 2003; PowerShot SD10 in the US
The Canon Digital IXUS i of September 2003 was the smallest branch of the Digital IXUS family — a fixed-lens micro-compact sold as the PowerShot SD10 Digital ELPH in North America and IXY Digital L in Japan. Unusually for the line it came in several body colours, and it dropped the zoom entirely in pursuit of a truly pocketable shape.
It pairs a 4-megapixel 1/2.5-inch CCD with a fixed 39mm-equivalent f/2.8 lens — no optical zoom at all. Movie clips record at 320x240 and 15fps, images store to SD/MMC cards, and power comes from the small proprietary NB-3L lithium-ion battery. At 90.3x47x18.5mm and 100g it was among the tiniest digicams of its era.
The IXUS i suits fans of minimalist single-focal-length shooting and collectors of unusual IXUS variants; the reasonably fast f/2.8 lens and 39mm view make it a pleasant street camera in good light. No zoom and a small screen mean it frustrates anyone expecting normal compact-camera flexibility.
Used checks centre on the NB-3L battery: confirm it still holds charge and a charger is included, though third-party cells remain available. SD/MMC storage is no problem today. Inspect the colour finish for wear, check the LCD for bleed, and test-shoot for CCD faults — Canon's mid-2000s CCD advisory affected several IXUS-era models, so a clean sample image matters.
