The Canon PowerShot SX230 HS is the latest incarnation of Canon’s highly popular pocket super-zoom. Announced in February 2011 to replace the year-old PowerShot SX210 IS, it’s the first SX model to carry the HS suffix. A step-down in resolution from the 14 Megapixel SX210, the SX230’s 12.1 Megapixel back-illuminated CMOS sensor and Digic 4 processor provide excellent low light performance combined with 1080p HD video recording
The SX230 HS sticks with the 14x optical zoom of its predecessor and the 3in screen, though the display resolution has been increased to 460k dots. Crucially, it adds a GPS receiver, the lack of which put its predecessor at a disadvantage compared with the earlier Sony Cyber-shot HX5 and Panasonic Lumix TZ10 / ZS7. Note: the PowerShot SX220 HS, released alongside the SX230 HS (in Europe only) lacks the GPS but is otherwise identical.
