I'm looking for a flip holder for dioptres as screwing one on and off underwater is a bit of a pain in the numpty. Here's what i have:
Nauticam 100mm macro port with threaded front
Subal 60 macro port with no threads
I'd like to be able to take two dioptres and ideally have one flipper for both ports. I may add a Nauticam port with threads for the 60 macro at some stage, but haven't decided yet.
I've had people tell me that the flips don't work very well and it's better to screw/unscrew as needed, but then others have said they only use the flip holders.
I really need some advice and guidance. Thanks.
