I assume you're using autofocus. My 90mm macro hunts quite a lot, even with the range switch set to the shortest. So, I've given that up in favor of manual focus and the "rocking focus" method described by others. Luckily, the Seafrogs housing allows for use of a focus gear which lets me use the lens in long range "portrait" mode.
You can split the difference if your camera/housing support back focus, where you separate the controls for focus and shutter. Then you still use AF to get the initial lock, and use the rocking method to finish the composition. Essential for the moving objects. With the 4/3, this worked pretty well. With the FF, I'm struggling a bit and do have the manual gears now. I need to get my wetsuit patched up so I can do some cheap practice in Monterey before the next trip to the west.
It's the initial lock that was my problem. The lens would continue to hunt and get to lock after some delay, which at that point wasn't that useful. My hit rate with "autofocus" was about 50%. With all manual focus, I'm up to about 80%, and I save some air not having to swear underwater.
I took my shots mostly at Moalboal, Cebu which isn't doing that well after the typhoon. In fact, I was the only diver at the resort. That was after 10 days at Dauin.
Now thinking about either Anilao or Lembeh, and as this could be one of my last trips, am at a decision point as to which would be best.
Both are cheap once you get there, but in the US, it's a lot easier to get to Manila. I wonder if the overlap between Anilao and Moalboal is greater than versus Lembeh.
Moalboal and Dauin were ok (although I was there also for the sardine shoal and whale sharks). I'd like to get to a truly macro-rich location, which I was told by another diver at Dauin would be Lembeh or Anilao.
