The 2008 Canon PowerShot SX1 IS was Canon's flagship bridge camera and the company's first non-DSLR built around a CMOS sensor, pairing 10MP with a 20x 28-560mm equivalent zoom.
The CMOS sensor bought it 4fps continuous shooting and full 1080p video - years ahead of its CCD stablemates - behind an f/2.8-5.7 stabilised zoom, vari-angle screen and AA power.
Its significance is as an odd flagship: RAW capture arrived free with firmware 2.0, making it a rare 2008 bridge camera with CMOS, RAW and Full HD in one body, and a quiet favourite of the digicam revival.
Used buying: confirm firmware 2.0+ so RAW works, cycle the full 20x zoom for errors and internal dust, and check the AA compartment for corrosion and the vari-angle screen hinge for wear.
