  1. First the Sony FE 24mm F/1.4 is a fantastic lens and I have used it underwater but would not recommend it for the simple reason that F/1.4 is great for astro and all but useless for U/W work. When shooting from behind a dome port of any size on full frame the rule of thumb is to shoot at F/13 or above for excerptible corners. Next issue is that for those looking to move into U/W photography they apply above water experience to equipment selection. I had a hard time wrapping my head around the idea that you can take a "kit" lens in combination it with a water contact optic like WWL-1B and get a wider AOV and much better image quality than with say the Sony FE 12-24 F/2.8 or 16-35 F/2.8. I suggest that you go to uwpmag.com, go to back issues at the top of the home page and enter Alex Mustard into the search engine. Alex has done two excellent reviews on water contact optics like WWL-1 and WACP-1. Enter my name Phil Rudin and you will find a wealth of information on shooting with Sony and associated products. Next I have reviewed WWL-1/1B twice, first with the 28mm F/2 and second with 28-60. The 28-60 is a better lens for both speed and optical quality. I have also reviewed lenses like Rokinon 18mm and Tamron 17-24mm F/2.8 using the Nauticam 180mm port on full frame. When I used the 24mm F/1.4 I was using a 230mm port and it still did not out preform the 28-60 with WWL-1B. Lots to consider and uwpmag.com along with this site are great sources of info. uwpmag.com is a free PDF download.
  2. The Sony FE 28-60+WWL-1B works equally well on the high 50+MP Sony A1 for CFWA and wide. The selfie demonstrates the 1/400th sec sync speed of the A1, great for reducing blown out highlights in the sky.
  3. No extension required with the n100-N120 port adapter snd the 8-15 works well with both MC-11 or Metabones. BE AWARE, Zen has different versions of the N120 100mm dome port. You need to be sure you get the one with the removable dome shade, the non removable shade will vignette towards the 8mm end of the lens. You can read my review for this lens with the Sony A7R II in issue #93 at uwpmag.com, this is a free PDF download.
  4. To be clear the mermaid photo is with the Sony A7C with the 28-60 kit lens and the Nauticam WWL-1 at 32mm. The A7C with the Nauticam 180mm dome port has a 40mm extension and is being used with the Tamron 17-28mm F/2.8 zoom lens. Nauticam supports this lens with zoom and focus gears. For best results Nauticam recommends the 230mm fisheye II dome port. I also used the Rokinon 18mm F/2.8 & 180mm port without any port extension. List lens is not listed on the Nauticam port charts. Both of these lenses are reviewed in the current issue of uwpmag.com alone with the Sony A7C system. I was testing the 180mm port using the 77mm Sea & Sea internal correction lens using a 67mm to 77mm stepup ring to fit the Tamron lens. The attached photo is the original with no cropping and then a crop to show the sharp detail. Also notice that human eye auto focus worked spot on even though I could not see anything but the outline of the diver in the frame in the dark water. The image was shot at ISO-640, F/10, 1/60th sec. The zoom was at 17mm.
  5. I agree with Davide, those are rubber spacers that secure the zoom gear parts. If you remove the focus/Zoom gear from the lens you will see several around the inner ring that goes around the focus/zoom ring on the lens. they always give you more than you need and some may fallout while installing the gear or just opening the package. The are defiantly not from the housing.
  6. To be clear the poster ask about the EOS R, the first full frame mirrorless camera released by Canon in 2018. This is the 30.3MP camera which did not feature IBIS or many of the other more modern mirrorless features. I reviewed this camera in the Jan/Feb 2019 issue #106 for uwpmag.com. If the poster would like to read the review it is in the back issues on the top of the home page and is a free PDF download. Best results were with the Canon 8-15mm fisheye zoom using the Canon lens adapter. Canon has made great strides in both camera features and RF native lenses since my early 2019 review. If the posters intension was the broader range of current Canon mirrorless cameras I would say the Canon mirrorless line has an excellent future for both lenses and camera bodies. The EOS R5 & 6 along with the new RF 100mm F/2.8L macro are some examples.
  7. Canon is doing an excellent job of quickly expanding their full frame mirrorless camera and lens line. The RF 100mm is an excellent example of this progression. According to a product discription by Ken Rockwell the lens is internal focus so no extension beyond the advertised length of the lens. At the 1.4:1 (1.4X) setting the working distance (lens to subject) from the end of the lens is 92mm (3.62 inches). If the lens fits perfictly behind the port glass and given the thickness of the glass I would guess a working distance of around 76mm (3") from the port. This is about the same working distance you would have with many closeup lenses of similar magnification. The physics of sensor size won't change so the DOF will remain the same on full frame as it would with another macro lens at the same F/number all else being equal. This shallower DOF is one of the many reasons some photographers love FF and fast lenses. I would guess that image quality with this lens will exceed the addition of a closeup lens to a 1:1 macro given the same magnification. I attached a photo taken on full frame at F/4 to demonstrate how the shallow DOF can separate subject from background. Sony A7R III, Sony FE 90mm macro, E-Turtle flash trigger in TTL with two Inon Z330 flashes.
  8. Price comparisons with 20th century glass in the 21st century does not really seem a appropriate to me. Sigma and Rokinon/Samyang make 14mm F/2.8 AF lenses for Sony mirrorless. Nikon has 14-24mm F/2.8 and 14-30mm F/4 lenses for the Nikon Z-series cameras and as listed above Sony also has 12-24mm F/2.8 $2999.00 and F/4 lenses. All of the Wide Sony fixed and zoom lenses work well with a 230mm dome and the proper extension. The Sony FE 12-24mm F/2.8 uses a 55mm extension so I am guessing the new 14mm F/1.8 should take about a 20mm to 40mm extension.
  9. The new Sony A1 camera with the Nauticam NA-A1 housing, Sony 28-60mm at 28mm, Nauticam WWL-1B, two Inon Z300 flashes at F/6.3, 1/160th ISO-500. Shot in the springs in North Florida. This is a GoPro with several INON accessories including a SD Selfie set and UFL-G140 SD conversion lens.
  10. I used the Nauticam 70 X 200mm float arms with the WWL-1 and CMC-1 and they seem to be the best fit buoyancy wise. Mermaid with WWL-1 and equipment photo is with the Nauticam 180mm dome port, Inon Z-330 flashes.
  11. The SMC-1 protrudes about 8mm beyond the buoyant mount allowing it to get as close to the port glass as possible. The 8mm difference will reduce the amount of magnification for the UCL-165 the question is exactly how much. Nauticam offer several buoyant mount holders that attach to mounting arms from several manufactures. This allows you to switch between WWL-1B and closeup lenses. A bit ocward with WWL-1 but still secures the lens while using the C/U lens.
  12. I use the Nauticam 140mm dome port with the removable sun shade. Be aware that any port you buy needs a removable shade or the shade will vignette at the 8mm circular fish end of the lens. I also use the Zen 230mm port for split shots again with the shade blades removed.
  13. Nauticam has posted the new Nauticam NA-A1 housing for the Flagship Sony A1 camera, the third housing with the new logo. I have had the camera for a few weeks and will have the housing in house tomorrow. It has many excellent features for underwater photographers including super fast AF and tracking speeds, up to 30 FPS, Flash sync up to 1/400th in full frame and 1/500th in APS-C, 8K video with out over heating, same Nauticam N100 port system and much much more. Should have the housing in the water by the weekend.
  14. The new WWL-1B on the NA-A7C's big brother.
