I had my very first UW photo dive on Saturday with the NA-XT2 housing and X-T2..
I was happy with my shambolic work and the camera wasn't the problem
NA-XT2, 2x retra strobes X-T2(v3 firmware)
I will update the X-T2 firmware as v4 sounds interesting as it gives me many of the X-H1 improvements (bar IBIS) and key=improves further the low light handling and autofocus speed... I was only using my 60mm (didn't try 10-24mm) so my thoughts based on that - I NEED a lot more time to learn/improve... <a data-flickr-embed="true" href="https://www.flickr.com/photos/7719989@N05/albums/72157693656739632"title="UW Pics"><img src="https://farm1.staticflickr.com/949/41196377955_3ac44c8396_z.jpg" width="640" height="427" alt="UW Pics"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> https://flic.kr/s/aHsmfL2TCU
