Cushion star, Sogod Bay, #Philippines

Another closish-focus wide-ish-angle attempt.

By underwater standards this isn't super close; 22cm to the focal plane, probably about 10cm to the dome. Much farther than than that and you start to see more backscatter from particulate in the water, and also problems illuminating the scene with small strobes like I have.

The lens is at 12mm on mu43, which is wider than above, and the level of detail in background is higher. The subject itself is probably familiar to most people that grew up near an ocean, temperate or tropical.
