Canon's 2000 3.3MP enthusiast compact — the first PowerShot G.
The 2000 Canon PowerShot G1 founded Canon's G-series: a 3.3MP enthusiast compact with a fast f/2.0-2.5 3x zoom, full manual control, and RAW capture when that was radical in a pocket camera.
A flip-out swivel LCD, hot shoe and lens thread completed a specification aimed squarely at photographers wanting SLR control in a compact.
Its significance is dynastic — every G-series through the current G7 X line descends from it — and CCD-era compacts like it are enjoying a digicam revival.
Used examples are cheap; check the CCD for the era's known sensor failures, the swivel LCD ribbon, and CF card door. Not to be confused with the much later, much larger-sensor PowerShot G1 X line.
