I have been putting together a relatively compact used underwater system and purchased a Sony RX100 mV with the Sony URX 100A housing on ebay. I'll be using a Sea Dragon 963 strobe and Sola 1200 video / focus light ( both purchased here ) as well. The housing has a 67mm threaded lens adapter. I am looking for advice on what accessries - especially WA wet lens would work well with these components.
