Sony RX100 IV underwater housing choices

And some amazing slow-motion video

Aluminum housings

Nauticam RX100 IV housing $995

This amazing housing has an HDMI port, optional vacuum check system, and a 67mm threaded port.

Recsea RX100 IV housing $920

This is the smallest aluminum housing, easy to single-hand and also has an optional vacuum check system & "quick-adapt" system.

Polycarbonate housings

Fantasea RX100 IV housing $499

Our favorite polycarbonate RX100 IV housing, it has great ergonomics and is very reliable.

Recsea RX100 IV CW housing $530

The smallest polycarbonate housing, it has 67mm threads on the port which we like.

Ikelite RX100 IV housing $550

This housing is larger than the others, but its clear design allows you to look inside the housing to check for water - a nice piece of mind.
