Canon has launched two SX series compact superzooms, the PowerShot SX280 HS and SX270 HS. The difference between the two is that the SX280 HS includes Wi-Fi connectivity and GPS, whereas the SX270 HS, which is not being announced by Canon USA, does not. Beyond that, both are 20x compact superzooms with 25-500mm equivalent image-stabilized lenses and 3 inch 460k dot LCD screens. Both feature 12MP back-lit CMOS sensors and the company’s latest Digic 6 processor.
