Pictures where taken with a MMIIEX and some of them with a single YS 60, but most with dual YS 60:s a 20 mm wide angle lens and a 16 mm wide angle lens.
Yes, the whale shark was in Sudan as well on the Sha'ab Rumi reefs eastern wall. A couple of years a go I did a dive on this part of the reef, because we wanted to explore all the perimeters of the reef - this part is very seldom dived. Then we almost landed on a giant manta ray when back rolling from the dingy. In 2001 I went to this part of the reef again with some other divers. I was telling them about what had happened there a few years ago and I joked about maybe we will see another manta. A few minutes into the dive, this young female whale shark swims by!!! Not very common waters for whale sharks, but almost anything is possible.
