  1. Interesting images on your website. Are you shooting all natural light? If so, I can definitely see where you find limitation in the D800. I agree that at greater than ISO800, grain definitely is visible. Everything shot wide angle in "Bonaire 2019" was done using an RS 13mm I had converted to communicate in full auto mode, and adapted to attach to a Nauticam housing by Andrej Belic. [Wetpixel article]
  2. If you are using the RS 13mm lens, get that converted for DSLR use and use your D800. A D800 quality housing where you can use the RS13mm (Nauticam, Seacam, Aquatica) should not be horrendously expensive at this point (honestly, I don't see that I would get much for my N800 and D800). Your composition is very nice, think about the results you could get with housed DSLR and the same RS lens.
  3. I've had really great workshops (I learned a LOT) on trips with Alex Mustard and with Erin Quigley. Granted, they both had their cameras in the water, but I found both to be almost infinitely available and teaching non-stop.
  4. Dove with Cortez Divers when on an Alex Mustard La Paz trip in 2017. They were very nice to us and straightforward - although my experience may be colored by the fact that our group took over 2 boats for 5 days consecutively, so they may have been more flexible/ accommodating for us. Of note: Like other Caribbean and Mexican dive operations, expect minimal assistance with gear except for tanks. They were careful with our camera gear from the dock to return, but no camera room, etc. The end of the dock/ entry to the boats also has the winch to lift boats out of the water immediately overhead (Watch your head!).
  5. The question I ask myself when I pack carry-on vs checked is "what is the minimum I need for this trip"? This usually leads me to put: camera, batteries, strobes, macro glass, WA glass, macro port in a ThinkTank backpack (no wheels!) and my housing, octo, dive computer, and a dive skin in a tiny roller. All this gets carried into the plane with me. Everything else (including big dome, arms, snoot, clothes, fins, dive gear etc) goes in checked bags. This way, if my checked bags never make it to whatever destination I'll be able to have a trip. It'll be spare and I'll depend on the kindness of strangers for arms and charger space, and I'll need to rent all the dive stuff minus my octo, but I'll not have a total "loss".
  6. Another question to ask (the one in my head) is when is Nikon going to revamp the 850? I waited on getting an 800 - the 810 was released about a month later. Checking on NikonRumors.com, it sounds like the D6 is in development pathway with a suggested release end 2019.
  7. I just got off the phone with a really nice person at Reef Photo who explained that the 70mm was the original recommendation (circa ~2013). The suggested extension for best results with the Nikon 16-35 f/4 VR lens is now 90mm.
  8. @ReefPhoto @Ryan @Nauticam Anyone care to reply to this question about an apparent Nauticam change in recommendation for extension tube with a 230mm optical glass dome from 70mm to 90mm?
  9. Interesting! I found this thread when I was searching for information/ discussions on this exact topic. When I bought my NA-D800 I was sold a 70mm extension to go with a Zen 230mm glass dome. I remember that the port chart at the time indicated that to be the "right" extension. I just saw the new port charts from Nauticam that now show a 90mm extension as recommended. Is this why my 16-35 images are always slightly blurry????
  10. When I went to Fiji I brought - Macro: 105, wet lenses x2 WA: RS 13mm, Sigma 15, Nikon 16-35, 230mm dome Fiji was (except for some bad weather that limited vis) more WA than macro. That said, I achieved one of my best anemonefish images with a 105 on that trip... From other folk on my trip who went to Beqa - the water is loaded with particulate and not requiring the "best" of corner sharpness. Why not the Tokina 10-17 with the Kenko, etc and the 8.5" dome? [sorry - not an expert if this will work.) It would seem like this would give you the most opportunities.

  13. The new iPad Pro uses USB-C connector. There's an interesting discussion about the connectivity via the USB-C and the iPad Pro here: https://9to5mac.com/2018/11/07/ipad-pro-usb-c-accessories/ @Davephd - FYI your link to "MyWebsite" in your signature only goes to https://www.icloud.com/
  14. Eitan - sounds like a good idea, however I'd be concerned that the bulk of a device on the back of a DSLR would then make it difficult to use a viewfinder/ eyepiece. That said, as mentioned I'd really like a larger view of the back LCD on my camera!
