  1. I know this is not the answer you are looking for, but thought you might appreciate another's experience. I'm a dedicated underwater video guy. I've tried all types of camera's for video with all their claims. However, I was never quiet satisfied with a number of things. It was not until I got a decent value priced pro video camera in a Gates Housing shooting 4K at 30p as I was MORE than happy. There are big differences in the build and performance. I also opted for the Gates Wide angle port.
  2. I shoot the same set up. The lens requires a dome port as one other has said. The camera is trying to focus on a "virtual" image and the "nodel" point is critical for sharp focus. Once I changed, I get very sharp focus in all lighting situations. I bought the Zen.
  3. Been there! There are multiple ways to accomplish this. External weights, internal weights; variations. Use us the stick on weights on the port. avioro8 is correct. However, I had a lot of trim to do, so opted for heavier weights (8 ozs.) I got from Gates. Velcro stick on with corresponding weights. Whatever, test at home in a tub of water BEFORE your trip. You will be glad. Bill
  4. It is not physical dimensions, it is button placement and match for the camera. Nauticam states the new housing is the FIRST to accommodate the D810. Call them.
  5. I've gone from the 1/2.3' or 5.6 crop factor (GoPro) to 4/3 and now 1" Sony Camcorder in 4K. The 1" Sony is simply remarkable. I'm moving to Full Frame Sony this year. Simply speaking I can see the quality and improved detail in larger sensors. However, with the higher end cameras, one has to utilize good technique to produce high results. GoPro and other cameras with new camera sensors us Computational photography that help with low light and high dynamic range scenes. The point & shoot video cameras are able to shoot multiple shots and combine them. The processing is getting sophisticated enough that this can even be done with moving subjects, without the user realizing that this is what their camera is doing. I have found that I capture better detail and dynamic range (color detail) with larger sensors and recommend the largest sensor you can afford for serious video composition. Check out the graphic attached.
  6. You have good equipment and doubt that it is lens or camera. You mentioned the "virtual image". You are on the right track. Wide angle and ports are HUGELY impacted by the Nodal point created by the port. The lens MUST match that. My source is a person that designs port/lens combinations. You likely cannot or do not want to spend that kind of money. However, Nauticam or your lens mfg. should be able to guide you. Good luck.
  7. You did not say why you need the door open. That is unusual for this camera. With that said the "doors" on cameras are held in place by small pins. You can either cut the pin or attempt to compress it so the door "pops" off.
  8. The Sea & Sea Internal Correction Lens is a unique optical tool designed to correct image abberration and distortion caused on wide angle lenses shooting behind a dome port. This lens attaches directly to the lens on your camera and is designed for Full Frame cameras behind large dome ports. When shooting wide angle underwater it is common practice to stop down the aperture to F8 or higher in order to product the best overall photo with sharp corners. It is commonly known that larger (smaller number) aperture causes distortion and blurring at the edges / corners of an underwater photo due to refraction differences in water vs air. This lens has been carefully designed to correct that difference and improve blurring and distortion. Curvature & distortion are improved by approximately 2 F-Stop values when using the Internal Correction Lens.
  9. I say "avoid buyers remorse"! It is terrible. Between smaller sensors and FF, it is both weight and size. I strongly suggest "try before you buy". Many shops will rent gear. Or, while on a trip, try to borrow gear you "think" you may buy. I've seen this often and other Photographers are eager to help. After going through the above, my wife and I ended up getting m34 systems. We shoot in raw. I can get all the gear without exception into one small roll-aboard. As for shooting. My wife shoots a Zen lens with the Oly 9-18. Pics are great. As for sensors, the real difference is the crop factor. On land, I'm a FF guy; l landscape and wild life. Detail of the field of view definitely favors FF. Short story? People cannot tell what format I shoot UW. It is less about the system than the 8" behind the view finder. Tim, makes a good point. Choose your format and then get as small and low weight as you can. My two cents. Good Luck
  10. As you can tell by reading this, it comes down to user experience/choice. However, Nauticam and Subal tend to lead the class.
  11. The critical factor is not "fit". It is the "nodal" point of the light coming through the port (especially wide angle). I've found Nauticam Technical capable in lens/port selections. Google "nodal point" in photography. I know one of the builders and this is their major complaints with customers; ignoring this factor. https://oceanity.com.au/blog/view/dome-port-positioning-visualiser-the-entrance-pupil
  12. I shoot the OM-D 5 with Oly 9-18 mm and Zen lens (adapter if needed). I am not shy about pushing the ISO to get the exterior shots. The interior needs good strobes. I moved up to the Sea and Sea YS-D2 Underwater Strobes. I shoot raw so I can do a little tweaking if necessary in post. After a couple of thousands shots, I might do the Nauticam 6 inch Dome Port for Panasonic 7-14mm Lens. BUT, do not get fixed focus lens. You will regret it. At these costs, you don't want buyers remorse :)
  13. I get your frustration. Can you find another person with a similar set up and try their bolt? The size MAY be stamped on a common item. If not, try to measure it in metric. If you can determine thread and length have anyone mail you one.
  14. This happens to all of us. I have always found going to your local store that sells high quality stainless steel screws/bolts. Take you stuff with you and it is highly likely you will find exactly what you want. Not worth fretting over. All manufacturers us "standard" screws/bolts.
  15. I go by the old adage in photography, "you get what you pay for". What do you "want or need" from the camera's performance? Since you are shooting mostly macro, low light (fast glass) should not be a big factor. Personally, I go for very accurate and fast focus. Sony is the king in that area. Even in full frame. Others may dissagree on this forum and that is okay. I've shot many cameras in 20+ years and the Sony wins for me every time with focus. If you also shoot video macro, it will be very noticeable. I shoot 4k 24p and it looks astonishing. Hope this helps some. Good luck!
