Canon's first Digital IXUS — 2000 metal-bodied 2MP CYGM-CCD compact, sold in the US as PowerShot S100 Digital ELPH
The original Digital IXUS of May 2000 transplanted the pocketable metal styling of Canon's APS IXUS film compacts into a digital camera. It was sold as the PowerShot S100 Digital ELPH in North America and the IXY Digital in Japan; UK sellers often list it by the model code PC1001 printed on the body.
It carried a 2-megapixel (1600x1200) 1/2.7-inch CCD — notably the only IXUS to use a CYGM colour filter rather than the usual RGBG — with a 35-70mm-equivalent f/2.8-4.0 2x zoom. There is no movie mode. Images write to CompactFlash cards and power comes from the NB-1L rechargeable lithium-ion battery, in a body of about 190g.
As the camera that launched the Digital IXUS/ELPH dynasty it now interests collectors and early-digicam enthusiasts more than everyday shooters: resolution is low by any modern measure, but the CYGM sensor gives its files a colour signature distinct from later IXUS models.
Check the NB-1L battery holds charge and that the CompactFlash slot pins are straight — CF cards and readers are still obtainable but cost more than SD. Confirm the lens cover, flash and LCD all function; twenty-five-year-old examples are often sold untested, and many listings under the PC1001 code are parts-only.
