Lastolite LL LS2416 Ezybox Hotshoe Metz 76 Adapter Bracket Description. The Flash Mount Adapter for the Ezybox II Hot Shoe Flash Softbox is made to allow your Metz 76 flash work with the Ezybox II. Because the Metz 76 flash has a unique physical design this workaround interface is required. The Metz 76 flash is larger & more powerful than normal shoe-mounted flashes & as such can particularly benefit from the larger Ezybox Hotshoe softbox.
