Hi, is this still available? Interested in the US.

Thanks for that legwork! That's good enough for me to hold off on this one.

This is so much the truth. Between the camera manufacturers moving things by 1mm and the housing manufacturers not doing conversions it's enough to make you pull your hair out (what is left of it).

Welcome! Your first question is likely going to be how to trigger strobes and also which strobes to trigger!

Looks like it is N120 afterall, but it also looks to be threaded so its a no-go with current N120 system. https://www.bluewaterphotostore.com/nauticam-n120-compact-port-extension-20 Says it needs the compact base adapter and compact system port, with threads. Also the picture on the for sale ad looks like it has threads (to me). https://fotografit.eu/upload_dir/pics/Nauticam/Lens-charts/2015_01_Nauticam-Port-Chart.pdf also the old port chart has only the 18XXX extensions with only the 18XXX ports/base. But again, im not 100% on this, its just Claude working for me.

Good points to consider. Thanks for raising them. 1) No zoom function to worry about. I'm OK (I think) using autofocus only. I can probably 3d print a modified focus gear down the road if I want that function. Worthy of consideration, though! 2) We're good there. The lens passes through the N100 end of the adapter with room to spare. 3) I would love clarification on this from anyone who knows for sure. This is part of what I'm trying to figure out.

The lens will fit entirelty through the N100 end of the N100/N120 adapter, so I think I'm OK on that front. Your point is well taken on whether this is really the lens I want to use. To be transparent, this is a practical solution, not a perfect one. I have the 14mm lens, and an extension to make that work is only a little money. A new 16-35 lens is a chunk of change that I'd rather not spend just right now while I'm getting started. Down the road, I'll probably go that route. Thanks for the input and advice. It's very appreciated. :)

Im going to say yes, but with reservations. If the lens uses zoom/focus gear and its supposed to be manipulated with the knob in the adapter, its misaligned. Does the lens fit through the N100 part completely And i think compact port extension system is actually N85, not N100. Here is the 30mm version with the same SKU# -edit Also the old compact port system looks its threaded attachment? Im sure someone has better info than my guessing, but it is over 10 years old system.

The only reason I think that might give you trouble is if the lens is too wide through the N100 part of the extension. Obviously the bottom part will but this is a fairly fat lens that only gets narrower right at the bottom, but I expect it's probably OK. You can test to see if the lens fits through the N100-N120 you already have. The question you haven't asked is if you really want to use this lens UW? Wide rectilinears have their uses of course, but the 180mm dome geometry requires the lens to be positioned with the entrance pupil forward of the optimum point at the dome centre of curvature to avoid vignetting, meaning the lens won't perform as well as it would properly positioned. You will see that the port chart shows the 250mm dome with an " * " meaning that is the optimum dome to use. The 180mm dome will certainly work and the images produced will be usable but other lenses may well do better particularly in the corners, There are other Sony lenses which may work better with the 180mm dome. I would suggest asking for experience using the Sony 180mm dome with the 14mm f1.8G lens, to see if you would want to do that. Apparently some of the new 16-35 lenses work quite well with the 180mm and I think there have been some tests published on this site from memory. The other question is what sort of photos are you thinking you might like to take and is a 14mm rectilinear the best option for this?

Last november just after a typhon we stayed one night in Cebu because the transfer to Malapascua was not allowed folowing the typhon. That's mean there wasn't a lot of boat and we was the first boat on the site. First dive ok ... end of the first many divers in the water... the second dive was not so go, less sharks and more boats/divers. I can't remember but they was beetween 15 and 20 boats on the surface.. For me it was the first time Malapascua and the last time For the transfer to Dauin... ok it's possible..... but it's a very long trip with car. We stayed near the Cebu harbour they are some mall there... it can be a good break. For us it was the only possibility then our boat started at 7am

I recently acquired a Nauticam housing for my Sony A7RII, and am a bit lost trying to figure out what extensions will/won’t work to house a lens I already have and would like to use. I could use some advice if anyone can help. The housing is the N100 system, and the lens I am trying to work with is the Sony FE 14mm f/1.8 GM. According to the Nauticam port chart, they recommend the N100 to N120 35mm adapter (which I have), followed by a N120 20mm extension (which I don't have), then the N120 180mm glass dome (which I have). The question I have: Forum member Onokai is selling a 100mm compact 20mm extension. (https://waterpixels.net/forums/topic/3635-brand-new-nauticam-compact-port-extension-ring-20-18520/#comment-25602) Would that extension work just as well as the N120 extension if I switched up the order to be 20mm extention → N100/120 adapter → 180mm glass dome? (Neither he or I are sure.) Or, is there a reason I don’t understand that the 20mm extension needs to come after the adapter, such that the compact extension won’t work?

Wants to buy Keldan Lights , 2 x 8x

yes it looks bit muddy, not sharp when shooting into the light, specially when shooting without any strobe or video lights

Hi, last time we did the Dauin Malapascua route on our 2023 philippines tour (Anilao, Coron,Tubbatah, Leyhte, Anda, Dauin, Malapascua). We did it by car and ferry. Very easy and confortable with our heavy dive and UW Camera equipment. Easily done in one day. We were not organized in advance and even miss the first early morning ferry from Negros to Cebu. After arrival Cebu island it took some time (arround 1.5h) to get a driver with car for transfer to Maya Port to Malapascua. We left Dauin arround 07.00 am and arrived Malapascua arround 05.00 pm. We paid 5000 Pesos for the car. If you organized in advance you should be able to do the trip in approx. 8 hours door to door. From my point of view no need for hotel, flight, etc. If you have some negotiation skills a car with driver is still very reasonable. We were diving Malapascua again (4th & last time) this spring and the car with driver from Cebu Port to Maya was 3200 Pesos. From Maya to Cebu airport we paid 2800 Pesos. Might be little more expensive at the moment due to fuel price increase worldwide. If you wanna see the treasures hurry up. There is a big underwater gopro circus going on at Kimbud Shoal. In April we had up to 28 boats anchoring. The ocean was bubbling. Guides told us in main season in may they have up to 50 boats (one full boat = 15-30 divers)☹️ +++++++the place is not big. Do not know how long the Treasher will play that game. Br Markus

The A7RIII was good, but the autofocus was lacking, but my biggest issue was the Ikelite housing. The buttons would often get stuck at depth, so I never felt it was reliable enough. Since this upcoming trip is a once-in-a-lifetime experience, I'd like to bring some new gear that I can trust.

Haha good point :)

Hi I made the trip Malapascua Harbour -> Cebu Harbour... 5 hours It is enough.... It will probably be a good choice to stay a night near Airport and take a flight next day... or if you can take a flight in the evening... why not. They are also the Ocean Jet from Cebu to Dauin but it take a long time... and you NEVER sure that the trip will take place or not... (I had bad experience with Ocean Jet last year, and if you are followin Ocean Jet on Facebook... you will have the alert of the cancelation...very offen) It is also possible to make a car trip from Cebu to the south of cebu island, and take the small ferry to make to cross to the next island. (15 minutes).. after that depending where you are less as 1 hour to the resort. For me the best choice is probably flying from Cebu to Dauin it is really fast and no expensive. Hope this helps

Great to have you with us,Will. There are no such thing as dumb questions. Only dumb answers. So post away! Best wishes
