I recently bought Olympus tough tg-5 + Olympus PT-058 underwater housing. Also bought a light & motion Sola 3800 video light and it's on its way. I went to a scuba diving trip and one of the divers had the same system and it works very well. However I've been searching forever on the internet and couldn't find the answer to this question: how to mount the video light to the housing? There seems to have 3 types of mounts: Sola photo ball mount, Sola video locline mount, and Sola YS mount. I remember seeing a ball shape thing attached to the housing unit of the fellow diver, which leads me to think I should buy the Sola photo ball mount, however the accessory mount of the housing is square-ish so I don't see how it can be mounted without some sort of adapter. What mount/adapter should I buy? Thanks in advance!
