Lastolite Ezybox Micro Softbox

The Ezybox Micro mounts directly to the speedlight rather than hanging off a stand and a bracket, which is what makes it the modifier that actually stays in the bag. It turns the flash from a hard point source into something broad enough to lose the red eye and the hard shadow behind the subject.

A silver interior spreads the light evenly across the front face instead of leaving a hot centre. 27 cm across and 65 grams, so it goes on and comes off between frames without rebalancing the camera.
