The Mk-V has an upgraded auto focus, but the buttons and lenses are the same. This gear is great for travel. It doesn't take up as much space as bigger camera systems, and yet the quality of the RX100 cameras are superb underwater.Having said that, I have since upgraded to a full-frame camera system. There goes my luggage space! I'm happy to send this amazing housing to a proud new happy owner, rather than have it stored in a camera bag.
If you've done your research you'll note that this housing setup has many additional goodies that make this an impressive value. Wide angle wet lens (i-Das uwl-04). Magnetic quick change lens system (no need to unscrew a wet lens to "burp" the air bubbles) and lens holder. If you don't already have a Sony RX100 IV or V, even though they aren't the latest versions of the camera, they are worth looking into!Especially because they have the advantage of being less expensive. And, the newer cameras have longer telephoto range, which really has no advantage when filming/shooting underwater. If you already have a camera for this... I'm excited for your upcoming dive footage! The magnetic lens mount is uncommon, and you don't have to use it, but in actuality it is a very handy addition.
Your lens sticks to your housing with powerful magnets, but if you want to change from wide angle to normal, you can clip the wide angle lens to the mount, which you can screw onto a dive light arm (not included). Everything is in "like new" condition save for the rubber on the handles.For some reason a thin layer of "skin" is peeling off the surface. This, of course, has no effect on the performance of the housing. I did change the battery for the moisture sensor within the past year, but I would recommend getting a new one just to be safe.
I have never once had a moisture problem with this housing, not even fogged glass or condensation, even with warm water, sunshine and lots of camera use.
