Hi, I can't tell you what you are not getting replies! Everything is OK from our end. Adam

Wishing the Wetpixel community the very happiest of New Year celebrations. Thank you all for your amazing and insightful input on the Wetpixel forums, sharing your wonderful imagery and participating in stunning Full Frame features. 2019 has been a year of consolidation for Wetpixel and we can now roll out new and exciting features in 2020. We hope that you are enjoying a joyful evening with family and friends and that 2020 will bring you safe diving, cooperative subjects, and amazing imagery.

Hi Marko, I use DeoxIT D series cleaner to clean off existing oxidisation, followed by Gold for long term protection. Adam

Just to gently steer this excellent discussion back on track... The original premise was: Rather than tell us why you actually chose a specific camera, what would you have if we were to ignore cost, lens and port ownership? You should not ignore factors like lens availability (e.g. is the lack of a native fisheye with Sony and Nikon full frame mirrorless cameras a deal breaker?), but blue sky thinking is most welcome. This is not real world of course. I think it is an interesting exercise though to see how "desirable" different camera models are being viewed and which features underwater shooters see as being important. Adam

The only new "flash trigger" at DEMA from Sea&Sea is a 90° prism that allows fiber optic slave triggering. There is a new TTL trigger from UWTechnics. Adam

Mine is on my strobe arms when I am shooting. It allows me to check status (including air pressure) without moving my eye far from the viewfinder. If I need to ditch my camera that badly, I don't think my computer is relevant any more! Like John, I had the issue with the Aladins blanking out when you fire a strobe. I am happy to report that with Suunto and Shearwater at least, this is no longer an issue. Adam

The other option is dedicated photographic trips (like the ones Wetpixel runs....) These are hugely productive and have the added bonus of having a bunch of photographers to bounce ideas and thoughts off! Adam

@Matt Sullivan There are actually quite a large group of shooters that prefer the D500. D500's AF is light years ahead of the D4's. Compared to full frame cameras, it also has better (and cheaper) lens options (for underwater) and will work with smaller domes. The only downside is the amazing high ISO performance of the big sensors, but given that corner performance is better with cropped sensors, this is not as big a deal as many think. In my mind, the only option that gives acceptable performance for wide angle (not fisheye) with high resolution cameras like the D850 is WACP. While amazing, the 13mm RS is actually pretty curved. I think the weight/bulk argument in favor of mirrorless full frame is completely moot when you have to add a WACP or 9" dome! @SimonPierce Just to be sure I am understanding your reasoning... You are willing to forgo effective AF for macro and a native fisheye option in order to use an LCD? How do you check for critical focus with the LCD? Peaking? Adam

I use the Nikon 8-15mm for fisheye. The 10-17mmTokina look horrible (and is a DX lens...) The Nikon 16mm doesn't really focus close enough. The 105mm is great for macro, although it has a horrible working distance compared to the 60mm on a cropped sensor. My question was more aimed at wide angle as opposed to fisheye. The reason for asking is that my "go-to" underwater camera is the D500. I do have a D850 and housing, but outside of some very specific uses, I find the D500 is a much better camera (underwater). Adam

Hi Simon, Which wide angle lenses do you use underwater? Adam

I would guess that your privacy settings for this video in Vimeo are set to private...it is the default. Adam

There is a new version of the YS-01 being released soon: https://wetpixel.com/articles/report-dema-2019/P3 Adam

IBIS or any other form of image stabilization is not really useful for underwater use. The water buoys up the weight of the housing, making hand holding possible at shutter speeds that are considerably slower than those possible on land. Think of the water acting as a "semi-tripod". Most people leave theirs switched off, to avoid battery drain. I don't see any reference to IBIS in their review. For what it is worth, the AF on the new full frame Sony cameras seems to be significantly better than that of the EOS R. However, I agree with the advice that full frame adds a bunch of complexity and expense that you could avoid with micro 4/3 or APS-C cameras. The lack of rinse bucket is not an issue. Tracking gear on a dive boat is simply a matter of being organized and telling others your needs/requirements. I dive globally with a huge variety of operators and most are good at taking are of gear, once they have been told how to do so! Adam

Thanks for starting us off Walt...why would (did) you chose the D850? I understand you wanting to use the RS, but you could use this with a D5, a D500 or an older Nikon full frame? I'm really wanting to drill down on why people are chosing cameras.. Entirely separately, are you at DEMA? Adam
