Camera Overview — Canon SX420 IS

The Canon PowerShot SX420 IS is a point-and-shoot compact camera built around a 1/2.3-inch, 20MP sensor powered by Canon's DIGIC 4+ image processor with iSAPS technology. It offers an ISO range of 100 to 1600, giving shooters a solid baseline for well-lit conditions through moderate indoor or low-light environments. The camera features optical image stabilization to help reduce camera shake during handheld shooting.

For autofocus, the SX420 IS uses a contrast detection system with face detection AF and subject tracking across 9 focus points, making it practical for capturing people and moving subjects. On the back, a fixed 3.0-inch TFT LCD display with 230,000 dots handles composition and image review duties — there is no viewfinder. Video recording is available at up to 25fps in 8-bit color, with a Standard color profile.

The camera stores images to SD, SDHC, and SDXC cards, and includes built-in Wi-Fi for wireless image sharing. A built-in pop-up flash supports Auto, Flash On, Slow Synchro, and Flash Off modes. The body is constructed from plastic with metal elements, weighs 325g, and measures 104.4 x 69.1 x 85.1 mm.

Battery life is rated at approximately 195 shots per charge using the NB-11LH lithium-ion pack.
