The Canon Speedlite 320EX Flashgun opens up new creative possibilities for EOS photographers; Wireless Slave technology, a bounce/swivel head and a constant LED light source for video work (600D and 1100D only). Despite being lightweight and portable, the Speedlite 320EX has a Guide Number of 32 (m, ISO 100) giving it enough power to illuminate large areas and distant subjects. The Speedlite 320EX’s flash head can be raised by 90 degrees and rotated left and right allowing flash to be bounced off walls and ceilings for a softer, shadow-free look. The angle of illumination may be zoomed to match the angle of view of a 24 or 50mm lens.
