The Lastolite Ezybox II Square, Medium (23.75 x 23.75") is a lightweight
light-shaping tool that adds a flattering, low contrast quality of light
to studio, battery-powered and shoe-mount flashes. The Ezybox has
removable interior and exterior diffusers that can be used in any
combination or not at all depending on your subject and desired effect.
With both inner baffle and front diffuser in use there is a 2.0 stop
reduction in output. Please note that the Ezybox requires separate
purchase of a speed ring for use.
