| Using the Fuji housing you'll have to get the Inon AD adaptor, then only Inon lenses will fit.
Inon do a wide angle lens and a dome port to go on front of it, both work out expensive but the results are excellent.
Strobe, Sea & Sea YS 110 is an excellent strobe, you will also need an arm and tray to mount it. I use the ULCS bits.
If you intend to use the strobe with the WAL & dome you won't get a wide enough coverage from the strobe, you'll need 2. You then have to play silly buggers with the fibre optic cables & connectors to get 2 to fire. Using just the WAL the YS110 is just OK.

p.s. I have an F50 and F10 and multiple Inon lenses and strobes. |
