This thread is a review on Olympus Underwater Housing PT-050 for XZ-1. The review is of my own opinion, base on years of using Canon's OEM underwater casing.
The Housing was tested from 20-23rd Feb in the Similan Islands, Phuket. The Housing was tested to a max depth of 30 metres. Underwater Photos will be posted in another thread.

The PT-050 is a relativity small and light... the back is made of clear Polycarbonate plastic with the front made of black, non-transparent plastic. The 67mm lens ring is threaded and made of stainless steel. The front port of the PT-050 is made of multiple coat glass. The housing handles well in my hand and is easy to control underwater.
The housing has positive buoyancy (floats) even with the camera and accessories loaded. While some divers isn't too worry about this... and a floating camera is better than a sinking camera if you lost your grip. I for one, perfer my camera to have negative buoyancy (sinks) as I normally attach the housing to my BCD from a layard.... the last thing I need is the housing 'floating' everywhere as I dive.
The bottom of the casing have the standard tripod mount that you could use to install onto a tray for your U/W Strobe system. I added a DIY lead weigh to make give the housing negative buoyancy (sinks).
The standard tripod mount screw thread...
Lead weigh brought from fish gears shop. Drill a hole, add a stainless steel screw and tape it up with rubber tape...
