I've got a Sony A6000 camera and planning to get Nauticam underwater housing for it.
I've noticed the box is often shown (in pictures, videos and such) with a lens, but I can't seem to find any details whatsoever regarding the lens underwater protection.
With that in mind, I'd like to ask: If I've got a decent Box and have the means to protect the camera underwater, the lenses aren't IN the box how are they protected?
I mean do I need special underwater lenses or are there specific cases for lenses too?
