  1. I am interested in your dome port shipping to Lake Park, Florida. Excepting the $300.00 price, have PayPal if you would like to be paid that way. Direct contact Phil Rudin at tropicalone@bellsouth.net
    Nauticam N120 8.5" acrylic dome port with shade (sku #18802) in pristine condition. Rarely used - no marks or scratches. Includes spare o-ring, neoprene cover and silicone grease. Retails new for $680, asking $300 + shipping in the US.
  2. Just to be clear the N-120 170mm Zen Underwater port has the removable shade for the circular end of the 8-15 zoom.
  3. My first suggestion would be to look at the Saga and Zen port charts at zen underwater.com and sagadive.com. These 100mm ports are very lens specific and according too the charts neither brand supports the Sigma full frame 15mm lens. In fact the only full frame lenses they support are the 8-15mm fisheye zooms. The Nauticam N120 140mm optical glass fisheye ports support both the sigma 15 and the outstanding Nikon 8-15mm fisheye zoom. The fisheye zoom requires the port with the removable shade for the 8mm and and an N120 40mm extension. The port with the removable shade is a bit more expensive but if you ever intend to move up to the 8-15 zoom it will have been money well spent. Photos are with the Nikon 8-15mm F/3.5-4.5 fisheye zoom at the circular 8mm and and the 15mm full frame end using a Nikon Z6 with Nikon lens adapter. The housing is Ikelite with the eight inch compact acrylic dome and Ikelite DS-161 flashes.
  4. I have not seen or tested the Tamron lens so have no comment regarding that lens other than to say it should work in a smaller port like Nauticam 180mm or ZEN 170mm with the proper extension. I am in the process of testing the new Sony FE 20mm F/1.8 with minimum focus distance of 18cm (the Tamron is 10.92cm). My lens will focus all the way to the glass with the 170 and 180mm ports. Photo touching the port glass, zen 170mm.
  5. Hi Eric, First of all 1:1 or life size on a full frame camera is an image area of apex. 36 X 24mm the frog photo is way greater than that, I would guess at least 1:3 or greater. With this lens to get to 1:1 the lens needs to be within 1 or 2 mm of the subject which just will not work with a dome port. The thickness of the port glass alone would prevent using it at full life size. With FF and a lens as wide as 15mm you would be best served with a 230mm or greater port diameter. Even if you were to use the lens for its excellent wide angle qualities by the time you added the gears it would not be cost effective. Rokinon/Samyang makes a 14mm F/2.8 AF lens for Canon, Nikon and Sony FF mirrorless which is also an excellent lens. This lens focuses to 20 cm which is a usable distance behind a 230mm port. You will find my review of that lens in back issue #112 jan/feb 2020 at uwpmag.com, this is a free PDF download. The Rokinon FE 14mmF/2.8 is now on sale in the US for under $500.00. This lens is a much better choice as a budget ultra wide (weitwinkel) rectilinear. Out of the water the Venus Laowa 15mm works quite well using focus peaking.
  6. The fisheye converter for the Sony FE 28mm F/2 snaps to the lens like a lens cap. The 28mm has a 49mm thread the new Sony FE 20mm F/1.8 (which shipped in the US today) has a 67mm threads so I would say not.
  7. Also Adam, Just out of curiosity I am interested to know why a firmware update which still does not raise the Z-cameras to the level of the current Sony tracking, eye AF, is in your words, "may make the Z series much more attractive for underwater use" I think theNikon Z6/Z7 are excellent cameras however they have few native lenses including NO Fisheye, (14-30 zoom and the coming 20mm). In November 2019 you rejected all Sony FF cameras for in your words, "The lack of a native fisheye makes it hard to justify the Sony full frame mirrorless cameras for underwater use when pretty much every other manufacturer offers one". I don't understand why the lack of a native fisheye would not apply to all camera brands.
  8. Hi Adam, The dome port used is the Ikelite Compact 8 inch dome with the 50mmport extension which is the Ikelite recommendation from the port chart. The dome port is the acrylic "Dry Lock" and it masters about six inches across and cost $350.00. The first image shooting up is at 17mm, ISO-640, F/18, 1/200th sec. This image also uses the S&S M82 internal correction lens which could be affecting the image with the smaller dome port. Second image is at 14mm, ISO-640, F/10, !/80th sec. Both images are full frame no crop.
  9. I have an older Think Tank Airport Security roller bag and a newer and smaller Think Tank Airport Advantage XT. The XT bag is lighter and as my roller bag has been weighted on every international trip I have taken in the past three years I have had to lighten the load in the roller bag. I have never had to weight my shoulder bag because the airlines assume it is lighter. My personal system is the Sony A7R IV with Nauticam housing and the ZEN 230mm dome which is heavy. I use the port with the Sony FE 12-24mm zoom Canon 8-15mm Fisheye zoom, FE 16-35 zoom, Zeiss 18mm and more. Because of the port size problem you have described I am now standing the port on its side in my shoulder bag along with several lenses and camera bodies. This allows me to put a lot of weight in a small bag that does not get scrutinized much. I bag the port with bubble wrap and cary the lenses in storage bags. The shoulder bag is an older Think Tank UrbanDisguise60V2.0
  10. That would be an article for another day but it does work with the Z 14-30 lens in the Ikelite housing with the 8 inch compact port if that is your question.
  11. Differences you may want to consider are depth ratings which range from 40 to 100 meters, optical glass or acrylic and the reason I selected the Zen port is ease of removing the dome shade blades. I use the Canon 8-15mm Fisheye zoom with the Metabones lens adapter and this lens will vignette at the 8mm circular end without the blades removed. This is the best port for splits with the fisheye zoom.
  12. Just finished up spending several days with the Nikon Z6 and Ikelite housing with the compact 8 inch dome port. The lenses I tested were the native Z 14-30mm rectilinear zoom and the 8-15mm Fisheye with the FTZ lens mount adapter. My test camera had the version 2.0 softwear not the new V. 3.0 which Adam addresses with this post. I found the version 2.0 to be an improvement over the v. 1.0 I first tested in late 2018 using the just released Z7. I shot the v. 2.0 in AF-S rather than to use the hit and miss tracking which appears to have been resolved with the V. 3.0 update. The Z6 is an excellent camera with superb build and image quality. The native 14-30mm is quite good for underwater use since most will be using higher F/stops in the F/11 to F/22 range. The 8-15mm Fisheye zooms gives the same performance on the Z6 with the adapter as the Canon 8-15 Fisheye does on the Sony A7 III with an adapter. My full review will be posting soon in issue #113 of uwpmag.com. Attached image, Large Mouth Bass, Ginnie Springs, Florida, Nikon Z6, Z 14-30mm F/4 S, at 17.5mm, ISO-640, F/13, 1/125th sec, Ikelite housing, 8 inch compact dome port, Two Ikelite DS-161 flash’s.
  13. Regarding the Tokina 10-17 zoom you are making the assumption that the lens will work with the A7R III and an adapter. If you look at the front page of divephotoguide.com you will see that the 10-17 is having compatibility issues with the Nikon Z6/7 cameras, I would want to know it will work before I would buy. Second is that the A7R III in APS-C provides about a 19mp image rather than the 24mp common with most current APS-C camera bodies. The Sigma is an option that has been tested but I think the most popular combo is the Canon 8-15 with the Metabones adapter. It is the most expensive option but is a bit like having two different lenses. At 15mm it is a full frame fisheye and at 8mm it is a circular fisheye. Not everyone likes the 8mm round image but I have found it fun to use. The port selections remain about the same as long as you buy a port with removable shade. The shade blocks the corners of the 8mm causing bad vignetting. Images with the Canon 8-15 and A7R II/III.
  14. That is a viewfinder designed to be used with the Nikonos cameras. It fits on the cold shoe on the top of the camera and the masks are for different lenses to cover the AOV of the lens. The dial on the viewfinder is for distance adjustment. Useful if you are still shooting a Nikonos film camera or to a collector perhaps.
