It's been more than what? 6 years, 7 years? When Heike and I went to Borneo a long time ago we also spent a few days on Mabul of the coast of Semporna to explore the underwater world there and particularly the island of Sipadan. This year we had the chance to grab two slots on a group tour to Mabul again and with a guaranteed trip to Sipadan we couldn't say 'no'. Sipadan is still good, a great place to see turtles, schools of Barracudas and Jacks as well as reef sharks, Mabul is more for the small critters and while the viz was a bit so and so we enjoyed our trip quite a bit. Photos definitely improved during those 6-7 years ... have a look at the 'Heart of Darkness' album to compare. Some photos are done with a new INON wide-angle wet-lens and Heike contributed a number of really good shots with the GoPro.
