Thanks for your additions gents. For my part, I doubt I'll pursue a manual gear as I'm happy with the autofocus when the lens is left open at 10mm, or just under. I'm saving my pennies for an a7 nauticam rig at present, so I'll probably keep going with the 10-17mm in the seafrogs until I can cough up for the wwl-1b.
