No Nikonos But...
I'm not a diver nor a Nikon shooter, at the time but always thought the
Nikonos line was way cool. This ain't the real thing but I wonder if they make these for Canon? https://www.hugyfot.com/housings/nikon-dslr/nikon-d850.html Yes, they do! https://www.hugyfot.com/housings/canon-dslr/canon-5dmkiv.html More on UW housing: https://www.backscatter.com/reviews/post/Nikon-D850-Underwater-Camera-Review Via: NikonRumors, Backscatter Nikonos galo https://duckduckgo.com/?q=nikon+nikonos&iax=images&ia=images -- teleportation kills |

Is there an advantage to taking a hulking DSLR underwater versus a smaller mirrorless camera? Depends on which product you’re comparing (and when .. what year). For example, I bought my dSLR housing system in 2010, I was unable to find any 4/3rds or mirrorless products (land camera & housing) that was able to incorporate a housed equivalent (which means lens & dome port) to the famous Nikon Nikkor 15mm wide angle (_still_ the benchmark for CFWA). Ballast? If you go too small, it’s lack of mass is a legitimate proble, especially for shake on video. But they are very “ballasty” when packed for airline transport carry-on ... I’m hoping that by now things have improved such that I’ll be able to find a smaller-than dSLR housed system for my next UW rig. FWIW, I’d like to stay with a housing like the Ikelite I have now, as I’ve found that their design makes it straightforward for me to rebuild it on my own, as part of the trade-off with the old Nikons was that some of its O-rings were not user-serviceable, whichmeant sending it out for annual service, which in the last few years was running nearly $200 per service. -hh |

As the joke goes, you can change it **once** during the dive, but most of the pics won’t be good afterwards... ....but seriously, there are some systems which use “wet” lens adapters which can be taken on/off underwater, usually taking a mid-focal to a wide, or to a macro. Because they’re “clip on”, their optical alignment isn’t as good, so their optical performance is never going to be as good. I have one of these with a “pre-GoPro” housed JVC compact video system to shoot (normal without) wide. When I did UW, i used W/A, Normal, and Macro. I had a 15mm, 28mm, 35mm .. plus a Close-Up Kit and macro tubes for my Nikonos, but currently shoot a 10-22 with an 8” dome and Canon7D (so 16mm-35mm equivalent), and a 60mm macro (same 1.6x crop body) with a flat port, which would be IIRC, ~150mm. Overall, not having the old Nikonos “goal posts” is an interesting trade-off: a little harder in some ways (auto focus quibbles when dark, housed dSLR is huge when getting close, etc), biut more flexible because it isn’t only just the goalpost’s fixed focus distance. -hh |

Do you mean the o rings on the Nikkonos, or the housing. In my diving days, the O rings for the housing were easily replaceable. IIRC I would coat them with a silicon based gel before every dive. -- PeterN |

Things have changed a bit. Wish I could safely dive. But, with a defibrillator and COPD, it would not be a smart thing to do. -- PeterN |

Do you mean the o rings on the Nikkonos, or the housing. The Nikonos has o-rings which are not user-serviceable. The only user ones were the lens (Onto body), strobe synch cord, battery compartment and film back. The o rings that aren’t serviceable on the Nikonos include the ones on the shafts for ISO, shutter, the release latch for the film back, plus some “Permanent” one’s, like the viewfinder. Similarly, the shaft o rings on Nikonos lenses were also non-serviceable: f/stop, focus. For the Ikelite housing, I can do literally everything. In my diving days, the O rings for the housing were easily replaceable. IIRC I would coat them with a silicon based gel before every dive. Which was basically only the first group I listed: film back, lens-to-body, synchronized cord. Most people wouldn’t do the battery compartment daily. With my housing, I typically do less maintenance than with the Nikonos. i’ll dive for a couple of days before opening the case up (refresh camera battery, memory card). The strobe batteries get pulled for recharge every other day and their o rings done at that time. Synch cord uses the Ikelite connectors, which is much better than the Nikkor design, so every 2-3 days for that instead of daily. It’s a bit more work to change over from WA to Macro while on the dive boat, as there’s the port in addition to the lens, plus I switch over to a different set of camera settings. -hh |

I wanted to have the maximum shots available on every dive. You are right, it's not fun opening a housing in rough water, and hoping to keep the inside, and camera dry. Also, I would think that most digital cameras are more sensitive to salt air than my Nikkormat, which my daughter confiscated, I also preferred the Ikelite because it accommodated various flash units. -- PeterN |

It’s a lot easier & cheaper to build or buy a tethered underwater UAV....these days,
probably no more expensive than one of the UW cameras we’re talking about. Ride the boat out, drop it off the side, drive t around & watch your own video feed. -hh |
