Just received my DS-125 back from Ikelite with the new slave sensor. It's working oh so sweet around the house here!!!
Leaving for Cozumel in the morning. I'll see how it works underwater with the 4040 in the Oly housing. It's conceivable some of the difficulty I was previously experiencing with proper exposure was secondary to my technique of internal strobe deflection/blocking.
I'll write a post, with gallery link after returning.
:cool:
