  1. Nauticam N100 to N120 35.5 mm port adapter with zoom/focus knob part #37303 in original packaging and excellent condition. For Sony A7 II, A7R II, A7s II and the new A-9. I also have the Nauticam 180mm optical glass port listed on page two. New $420.00 Sale $325.00.
  2. I use the Nauticam 45 degree viewfinder with my Nauticam NA-EM1 II housing and have always favored the 45 over the 180 because I do a lot of macro. If you are not aware the newer Mirrorless camera housings use a different Nauticam viewfinder than the DSLR housings and the older mirrorless housings that required a rear window change to work. I am not sure that the Inon 45 can be adapted to these newer housings.

  4. What housing are you using and why the 30mm extension with the 170mm port.
  5. DMshore, I reviewed the Sony NEX-7 (APS-C sensor size) in 2012 using the Sony 24mm E F/1.8ZA lens. This is a 36mm equivalent (61 v 47 degrees) lens but focuses a bit closer than the Panasonic so I think these images would be very close. The Panasonic 25mm would not be my first choice but as bubffm pointed out it is a portrait style lens that will focus to 25cm (9.84inches). Plenty of fish and other life in Bonaire that qualify for portrait status. The lens should work nicely in your Excellent ZEN 170mm port. A C/U lens used inside the dome would not work well but if you have a macro port that can get the lens very close to the port glass it is worth a try. Picking the proper subject for the AOV and distance from the lens is the key to getting interesting subjects. Hope this helps

  7. While Tom's method removes the blue ring (CA) I like the black background better than the white. In Lightroom I made the normal corrections one might make like cropping to square, color, etc. This image was taken with the Sony A7R II, Canon 8-15mm at 8mm, metabones adapter using Zen 100mm port and Nauticam NA-A7II housing. Once I had made some corrections I used the Lens Corrections menu in the manual setting and simply moved the lens distortion to -12 to remove the blue ring. The Lightroom lens correction setting for the Canon 8-15 zoom completely distorted the image so I never use that. I did not have the aromatic adoration box checked in the lens correction panel. More than one way to deal with this issue and not remove the black background.
  8. New review posted in uwpmag.com issue #97 now available free for download.
  9. These are examples shot with the Olympus 8mm F/1.8 Fisheye, E-M1 II, Nauticam NA-EM1II housing, Nauticam N85 140mm optical glass dome port and N85 extension 17. One close focus and one at about 18 inches.
  10. Yes and it is on the list near the bottom. Last photo is the 16-35mm F/4 with the gear installed. you can contact me direct at tropicalone@bellsouth.net
  11. Not quite sure what you are asking. Both chart photos were taken with the type I ZEN 170mm port, one with a N85 20mm extension and one with an N85 30mm extension. I also had the type II N85 170mm port for testing long ago when it first arrived but stuck with the Type I port so I could use it with the 12-40, 12mm, papa 8mm fisheye and more. I have never own the 9-18mm zoom and my only use was for My only use of the M 9-18mm zoom was for a review of Olympus E-PL1 in Olympus housing with ZEN 100mm port at for sharks at Stuart Coves and a fluorescence review using Ikelite EM-5 II housing, eight inch dome and fluor equipment. I used the 9-18 because I had a yellow barrier filter with the same threads as the lens.
  12. Sony Flash Trigger $220.00 SALE $165.00, this item is sold.
  13. These charts are to assist ZEN Underwater in evaluating some port and extension combinations. Most are sent on to Zen and not held on my personal computer so I only have these two examples of the ZEN 170mm port with 20mm and 30mm extensions. I am only one source for this information and Zen does not base their final recommendations on my charts alone. I am far more interested in how the lens/dome combo works in the real world and what images sell regardless of corner sharpness. All photos are with the Panasonic 7-14mm zoom in a Nauticam NA-EM1 housing. with the listed extensions, first photo (310213) 7mm at F/7.1 and 30mm extension, second photo ( 310103) 7mm at F/5.6 with 20mm extension, Both taken at two feet, Conch 7mm with 20mm extension at F/13, apex. three inches to subject.
  14. The Nauticam 180mm dome is the 110mm radius. I am not a physics guy so I will not attempt to argue Wolfgang's calculations they seem quite the same as those used back in the film days. I have however been told by those developing the Zen and Nauticam dome systems and extensions lengths that differences exist between DSLR cameras with a mirror box and mirrorless cameras. An example would be like performance between say an 18mm lens on a full frame Sony A7R II with a Nauticam 200mm dome port and an 18mm lens on a full frame Nik/Can with a Nauticam 230mm (greater radius) port using the same formula to calculate the extension length. Not sure why this happens but it seems to. I have attached another way of testing, this is the Zen 200mm port, Nauticam NA-A7RII housing, Sony A7R II, Zeiss 18mm F/2.8 @ around F/8 at two feet. Try doing this all day with several ports and extensions. The chart is mostly flat which does not at all represent how you would be shooting underwater.
  15. Have you looked at this battery pack, http://reefphoto.com/shop/index.php?main_page=advanced_search_result&search_in_description=0&keyword=a6500+battery+pack

  17. So simplistically if the AOV difference between 170mm and 200mm is 30 degrees without distorsion, would that give the Nauticam 180mm port also with the same r=110mm about a 111+ AOV without distorsion assuming proper placement? Or very limited corner distortion at the 7mm end of the Olympus lens.
  18. The extension with zoom knob I showed in the photo above is as I said are for a Nauticam NA-A7rII housing. It is the n100 to N120 40mm port adapter for Sony housings. With my Nauticam NA-EM1II housing and Olympus 7-14mm zoom I use the N85 to N120 60mm port adapter WITHOUT the zoom knob and the bolt on 10mm extension which threads to the port. This extension takes the place of the port mount and is on the port at all times. So that gives me 70mm's of extension with the ZEN Underwater 200 port. The ZEN 170 port uses the same N85-N120 port adapter but with a 20mm extension. Nauticam 180 port uses the N85 to N120 55mm port adapter without any additional extension because the port already has built-in extension because of the design of the port mount. http://reefphoto.com/shop/index.php?main_page=product_info&cPath=80_148_149&products_id=7471 http://reefphoto.com/shop/index.php?main_page=product_info&cPath=80_148_150&products_id=4608
  19. Wolfgang: The Olympus 7-14 works very well with the ZEN 200 dome port. I used this port with the Nauticam system for the Sony A7R II ZEN has now discontinued the 200mm. Your choices would now be Zen 170, Nauticam 180 and Zen 230. I used the Panasonic 7-14 with the Zen 170 port but have not used the Zen 170 port with the Olympus 7-14. As you would expect with a larger port the results with the Zen 200mm and only 7-14 were better in the corners than with the Pana 7-14 and the Zen 170 port. Attached shots were taken at F/7.1 and F/6.3 so not as high as you could go to improve corners. The AngleFish is at the 14mm end the others are at the 7mm end. The bigger dome works better for the split images. Shot with EM1 II and Nauticam NA-EM1II housing.
  20. I use the ZEN 200mm n120 optical glass port for the Olympus 7-14 and other lenses. It can be paired with the N85-N120 extension with a wheel for zoom or focus. It you use the focus wheel on the housing with the standard zoom gear you can then get focus with the gear off the port extension. See attached parts. The photo is the same type of configuration with the N100-N120 port extension with focus wheel on the Nauticam Sony A7 II housing. http://reefphoto.com/shop/index.php?main_page=product_info&cPath=80_148_149&products_id=7472 http://reefphoto.com/shop/index.php?main_page=advanced_search_result&search_in_description=0&keyword=olympus+7-14mm+focus+gear

  22. I have used the ZEN Underwater optical glass ports for the Panasonic 8mm Fisheye in Nauticam housings for EM-5 and EM1, also for the Canon 8-15mmm Fisheye zoom for Sony A7R II and it works quite well for such a small package. I now use the Nauticam 140mm also quite good for the Olympus 8mm because the Zen port does not work with this lens in the Nauticam housing. Regarding larger ports I am also using the ZEN 200mm port with the Olympus 8mm Fisheye for larger subjects and over/under shots.
  23. I have been using two Nauticam 2X10 inch (more less) float arms, around 700g (24oz) lift with the Olympus 7-14 zoom, NA-EM1II housing and Zen 200mm port, with two Inon Z-240 strobes. Works for me. For the Olympus 8mm I use the Nauticam 140mm port with 17mm extension with two Inon Z-240's and no strobe arms.
