Hi Dave, verry sorry, my mistake. I mispelled may be something. I also have only one 2032 battery on my D850 housing vacuum system. Br Markus

Hi Dave, if your happy to work with the rechargeable cells it is fine for me. Fact is that rechargeable 2032 have a capacity of 45 mAh and the Li cell between 210-240 mAh. For me, that's a significant capacity difference. Sorry ,but I do'nt want to change cells every few days, but I agree on your argument regarding waste. FYI: I started my dive trip in march with new installed CR2032 on my Nauticam vacuum system. I did 25 diving days and left the vacuum system running several days overnight (f.e. Malapascua, you leave 05.00 am...I think you know) and even left the vacuum running several times for 2 full days (too lazy open the housing). It was still running on the last diving day without change batteries. I just made a quick calculation and I roughly estimade more than 300 hours the vaccuum system was working with two CR2032.

Hi Dave, thanks for hint. I have also checked after reading your message and must agree with Chris. The capacity of rechargeable button cells are very low. Nothing compared with the lithium battery one. You won't be happy using them. Br Markus

Hi, I’ve been using the Nikon 8-15mm lens in combination with a Kenko 1.4 teleconverter for several years now. I’m actually quite satisfied with the image quality. I mostly work within the 11–15mm range, shooting through a Seacam fisheye port. I’ve quickly picked a few sample images attached here. If you’re interested, I’d be happy to provide you with detailed metadata for the images. Best regards, Markus

PLUS some blue reduction rings. Thanks Dave for sharing the files. The reductions fit perfect and did a great job reducing backscatter on my Philippines trip March/April

Hi Dave, thanx for sharing. Will download and print in the next few days. Rating will follow. But I`m shure your design will work. Already printed your design of macro rings for retra flash and used it on my current philippines dive trip. They fit and worked perfect. Backscatter was noticeably reduced. Just returned back home after 6 weeks and need some time for detailed review. Br Markus

Hi Dave, interested in the new designed connectors. It would be great if you shared the print files. Br Markus

Hi, any coatings on UW- ports are on the inner surface. Br Markus

Hi, I use Ceroxid (Cerium (IV) oxide). It is a powder widely used as a high performance polishing agent in the glass industry. I bought some stuff on ebay but it shoud be available on internet shops as well. Watermarks are easily to remove and I was even able to remove small scratches with. I do it without polishing machine, so it takes a bit of time. But worth to do it. Br Markus

Hi Jens, I am 100% with you. Solving problems with UWT is a nightmare. They tell you it is always a customer problem.... Wrong settings, change batteries, clean contacts and on and on and on .......... Bought UWT trigger for my NA-D850 using Seacam 150D. Trigger did not work at all after arrival. A long long story with a lot ot suggestions from UWT did not work. After one year of discussions they replaced trigger. This one was working till end of last year. To find a reasonable solution for new problem I contact UWT via email. Same story.. Change batteries, clean contacts........ That is what you get from the "world finest TTL trigger". The price for the trigger is ++++. Support is -----. Next time I will use a company closer to my location if possible or one that have good customer support. Prices for triggers are similar and I hope for better support. Br Markus

Hi, 100% agree with Chris. Eizo is the benchmark. Tested several monitor and ended up with Eizo for my picture editing. Little pricey, but really true color after right calibration, long warranty and no dead pixel. And my monitor is working for years now without any issue. Second monitor together wit the Eizo I use a cheap LG but this one is only for the toolbars, open folders, rename/edit files etc., not for picture editing. Br Markus

100% agree Jens. Used a few UW strobes (Inon D180, D2000, Z-240 Type2-4, Nikon Sb-800 with Sealux housing, Nikonos SB-105, Seacam 150D, Retra Pro Max, and Subtronic Pro270 + 160) Subtronic had a very good light quality when there were only few providers in earlier times and they still offer good performance today. While I used the Subtronics, service was outstanding compared to other manufacturers . Quick & cheap, always communicative. They even modified the strobes to my liking for little money. From my point of view a 100% + is that they still offer reliable repair service. Anyone still interested in sustainability these days? Hmmmh☹️

Hi Dave, would you share the 3D/CAD files of the knobs. I also sometimes mix up the power and mode knob due to almost same design (only length is differnt). I was thinking to design a clip-on knop. But if your design solves also the "salt problem"👍😃. To be honest, I hadn't figured out the salt problem until today. Will later remove a knop on my strobe to get an idea how much salt stuck there.

Hi, I don`t want to go too deep. Just give me a definition of "sharp". Do I have a "sharp" photo, just with a so called sharp lens. @ Adventurer: From my point of view I`m not clearly shure what you would like to compare. Only mirrorless lenses or also full frame DSLR lenses which can be used with adaptor. By the way, who can let me know the OPTICAL difference using full frame f.e. 8-15mm lens on a mirrorless or a Dslr system. FYI: Fisheyelens I use 13mm RS & 8-15mm on Nikon DSLR & Im lucky with the results. BrMarkus

Hi all, this is not a UW photo issue but I just want to inform the community as many of us want to dive and take pics at Socorro. I do not know if all of you have knowledge about the situation. Solmar V Liveaboard takes bookings and the do not go out. They cancel there trips shortly before departure and do not refund customers. They did it in the past and still do it. I was personal involved in October with cancellation less than 24 hours before departure. See kink on Scubaboard wih reports of victims.
