I use Nikon D500 in Nauticam housing. (currently use fiber only)
I had enough of Burned-out bulb in my Sea&Sea YS-D1 (Last time - in the first day in Socorro islands)
I can get the Inon Z-330 and the Iklite DS-160 for the same price.
Do you think that the bulky DS-160 have any advantage of the Z330? (except the 2ms faster recycle time)
