I've been getting weird circular reflection when I put together the setup above, see left-bottom at the attached image (shot in RAW, no post processing). This image is taken on an overcast day, in fresh water at 115ft depth so not much bright light was present. Most of my pictures exhibit this kind of an artifact. I am in touch with Jack and his staff from OpticalOceanSales.com to better characterize the source of this reflection and I will post more detailed report as soon as I will have more information. I am just about to leave on an overseas trip and I am looking for any input whether anyone experienced similar phenomena, any tips that I can use on my trip are much appreciated. In addition, as I will be looking at alternatives to this setup, any suggestion what you use with your LX5 and 10bar housing as a wide angle solution and how well does it work for you will help my decision. Thanks, Mark
