Pradi,
Sorry Oom, I am screw up u/w photographer, never like it and never will. I do land photo for fun only. I like U/W VIDEO cause it almost always get what ur eyes see ( with good video cameras ).
All I know Nikonos V is discountinued now. It is a nice camera for its design age. Unless u dive in decent visibility like Bali or at least 60 feet without much particles, U/W photography is just sad...sad....sad...... Maybe macro u can do easier in not so good water. One thing I know is, u better have GOOD lights or else....keep that camera.
Sorry can't help, I'm blind on U/W photography.
I'm in Jakarta, Pak.
If u want Asian forum that can help you with 35mm still U/W photo, try
www.finsonline.com, based in Singapore, there are two semi-pro photographers on the forum.
Another forum u may try is
www.scubaboard.com, I think this is US based, this forum I don't know well.
The two photographers I know here are Anderson and Abriapnea but maybe they are doing digital now, well they did start with a 35mm Nikonos V, I am sure.
Chief and Abri....where are you...please help my fellow country man.

Thank you.
Good Luck.
