  1. So, rumors of a possible D800 are now circulating again. A lot of people are saying it will be a D700-sized full frame camera with a 36 (yes, 36!) megapixel sensor. Particularly I don't need that much resolution, and I think it will even bring some storage problems, but if Nikon does come up with a F100 sized camera and AF comparable to the D2x I will probably buy it. Estimated price is not cheap though, $4000! Here are links for the latest rumor pages with more spec details:

    Anybody with some inside info willing to share? Announcement is rumored to be in about 1 or 2 months.


  2. It really depends on your budget. If you don't have much, I think Bali is the best option. It is relatively cheap (doesn't require domestic flights) and excellent diving. If you have more to spend, there are many options: Wakatobi, Sulawesi, Raja Ampat...


  3. Bill makes some great points. Long zoom lenses rarely work well underwater, I think 17(or 18)-55 is the most common zoom used underwater other than the Tokina 10-17, which is a great lens. For the purpose you state (fish portraits and macro) the best choices for you are the 60 or 105 macros, and which one you chose will depend on how much magnification you want.


  4. The reason you don't see them more often (or at all in some places) is that they are very vulnerable to predation at this stage, so it is a very short stage. We call it the settlement stage. Morays (like most reef fish) have a pelagic larval stage, when the transparent larvae stay up to three months in the open ocean, followed by a sedentary adult stage, when juveniles and adults stay close to their reefs. Larvae don't swim well and are small, so any predator can snatch them. Juveniles and adults have their ways to protect themselves. So one of the most dangerous portions of an eel's (and any fish) life is when they are transforming from larvae to sedentary juvenile. This phase only lasts for 2-3 days, and that's the phase where you caught this fish. In addition, because they are so vulnerable, they are also very secretive, so it was really lucky for you to find it swimming in the open like that.


  5. The only one in the list that I use is the Nikon 17-55. It's great above water, and behind my Subal fish-eye dome port is also great underwater. Overall a really good fish portrait and moderately wide lens. As others mentioned, not very wide, but if I want to go wide I just use my fisheye.

     

    The large size on the Subal is a problem. The lens fits very tightly in the extension ring/port and it's a bit of a hassle to mount it. But my system has the older, narrower Subal ports.
