nauticam for RX100MKII has a leak detector??
backflip entry with a camera in hand.. no...never...
u have to tell the crew what is you set up when u have expensive diving equipment.. and how you want it to be handled. but i tot you backroll with you camera anyway! why do you care how its handled kee kee.
well.. logic plays a part.. if u going to stack.. then u really have to be careful right... in the beginning. i am going to stack by screwing on the new lens on top of the other....
the magnet give you an option of an quick switch from maybe a +10 to an +5+
Maybe for the wide angle lens ... It can be a bit heavy...
I mean the moisture sensor, not the fancy vacuum sensor.
I don't know where you normally dive, but different area you get different service. In Indonesia, yes most dive crew hand your camera to you. In Thailand liveaboard, I back flip into water because we mostly use dinghy and if the current is not strong, yes the one person screw hand me my camera. In one of the dive in Thaisland, the current was so strong, we jump off the live aboard with our camera and decent very quickly. 5 seconds into the water I was already 20 feet away from the boat.
If you dive in US, you're on your own, they don't have nice camera shelf like many boats in Indonesia, they only have one bucket for all camera gear. So good luck dipping your rig in the bucket share with many people and things get scratch or knock off. I learn a couple months ago that some people have their own flexible cooler bag to put their camera in, so no rinsing until they get back to land to avoid mishandle by crew or other divers.
Bottom line, expect the worse situation that it's being handle, whether it's by the crew, your dive buddy etc.
