The dome diffuser for the YS-D3 produces a nice, even, 150-degree beam. This is great for wide-angle photography, especially with a fisheye lens.
The Sea & Sea YS-D3 Dome Diffuser Strobes increases the beam angle of the YS-D3 strobe to 170°×150°. This accessory is essential when shooting wide-angle especially when using the fisheye lens as it requires soft lighting. It also drops its guide number by 1.5EV when fitted.
