  1. Definitely not coral. Almost certainly a hydroid. Size? Did you touch it, did it sting?
  2. I missed that post. Link, or post again. I still am unable to navigate this new version of Wetpixel.
  3. My wife is a fish geek.....she also thinks it is a juv graysby. See this for example: https://www.gettyimages.com/detail/photo/graysby-royalty-free-image/832513138
  4. #3 looks like a piece of broken off red sponge.
  5. I'm on travel with my OM10 and two lens. The 14-42mm just failed. I'm not keen on spending 2 weeks in Bonaire shooting only macro with my 30mm. What happens if I use the 30mm with my WWL-1?
  6. Seems reasonable, but it depends on what you like to shoot underwater. The 16-35 with a dome will do fine for wideangle stuff, but if there is that fish you want to capture it might be frustrating. Also, snorkeling, the smaller the camera the better, at least for me. So I'd be tempted to stick with the RX100!
  7. The tray can be used with the add-on piece on the left ir the right, whatever works best for you.
  8. Agreed. I've got 5 years on my two D1s, one of which was purchased used. No issues. The "zero dollars" comment is likely related to a broken one....if there are no parts and thus not repairable it is wirth nothing.
  9. I've owned the 12-50 zoom with its special port, the 60mm macro and the 30mm macro. They all serve their purpose, but the 60mm macro is VERY nice! It will fit in the 12-50 port...new new port needed. It is the lens of choice for small stuff, like in Anilao and Lembeh. If the 60mm is too much power, the 30mm is very nice, and focusses really quickly, but will need a different port. For macro, I think both the dedicated macro lens are sharper than the 43mm macro setting on the 12-50 zoom, but that 43 is a very useful power.
  10. I have two arms on each side. My braided handle is attached at the middle clamp on each side so when the camera is lifted/carried the arms closest to the camera are holding the camera. I've also rigged mine with the braided handle clipped to the tops of the tray sides, but with the braided piece also clipped to the mid-point of the arms, as in the attached picture. This keeps the arms from swinging around while the camera is carried. I like this method, and am going to stick with it, I think. it is easy to unclip the arms from the braid after I'm in the water, or to clip it back before I exit.
  11. Is this advice in metric? What is the source of this advice; I've never heard it before, and it contradicts some other guidelines like PADI, which says (for a 7mm wetsuit in salt water) 10% of body weight PLUS 1.5-3kg. Conversion to fresh water (the OP's "lakes and reservoirs") then means subtracting about 3.5% of the body weight. So the PADI guideline for a 7mm in fresh water would be 6.5% of body weight, PLUS 1.5-3kg. Example: 80kg person would need 5.2kg plus 1.5-3kg, so 6.7 to 8.2kg. The OP's in-water test with 6 lbs was way too little; 15-18 lbs would be closer to the guideline. I'd run the test again, varying the weight a lot. Interestingly, your "weight divided by 10, minus 1" gives the same answer for someone who weighs about 92kg.... The point is, the buoyancy of the 7mm wetsuit is what is important, but the actual weight needed depends on the volume of neoprene in it, which is correlated with body weight, and depends on salt or fresh water. I agree completely that all these calculations are only guidelines, and in-water tests are the only number to believe.
  12. I get close with the S-AF on a thumb button, then fine-tune wuth the wheel. I was confused. My 30mm zoom gear is Nauticam and of course works fine. The 60mm gear is 3D printed but not by Deepshots; it slips fore-and-aft, and has no set screws.
  13. Well, yes, but they are not as nice to use as the offical Nauticam gears. I have two Deepshots for my two macro lens (30 and 60) and, yes, they do work, but they are much more finicky to use because they slide around on the lens and it is too easy to get them in a position where the small wheel to focus with binds. And I focus a lot in macro. But, they are much cheaper.
  14. I use this with the 29mm port for my 14-42mm EZ lens to give me a 46mm port to use with my 30mm macro lens.
  15. And this is another reason the vacuum systems are nice....they preload those o-rings a bit.
