Canon has today announced an update to its mid-range Speedlite 430 EX flash - the Speedlite 430EX II. The new model offers 20% shorter recycle times, a silent recycle process to minimize distraction and a new quick release and locking mechanism amongst other new features. When attached to an EOS camera the Speedlite 430EX II detects the sensor size and adjusts its angle of coverage accordingly.
