number of 79 (ft.) / 24 (m) at ISO 100. The Tele position
boosts the guide number to 105 (ft.) / 32 (m) at ISO 100 while
providing coverage for lenses 50mm and longer (full-frame).
Lightweight,
pocket-sized, grip-friendly, and with an intuitive,
easy-to-operate design, the Speedlite 320EX is powered by 4 AA
batteries (not included) and recharges silently in
approximately 2 seconds.

vertical and horizontal bounce capability provides an extended
range of possible lighting effects.
