We are using the AOI wide-angle lens as an addition to our underwater recording equipment. Here are some examples of how the lens significantly improves the focusing capability of the GoPro (which doesn't focus closer than 60 cm). With the AOI lens, you can practically touch objects, and although the perfect focus is achieved at around 8 cm, it also performs exceptionally well at shorter distances. I'm sharing some photos of the equipment we use and a few videos for you to see its capabilities. I hope you like them.
This setup configuration is GoPro 10, Nitescuba NSV60 video lights, AOI lens and Nitescuba camera tray.
