  1. I know that my partners in the US had responded to Joe in early January. But I do want to repeat here. (I didn't notice this post until now because I was at a diving trip then) Both the MWL-1 and SMC-1 were designed for using underwater. You will see vignette when there is no water: 1) between the rear end of the lens and the port glass; and 2) water in front of the lens. Edward
  2. I would suggest for anyone who is interested of, or not sure of the rationale behind, the WACP to read the review by the Honorable Dr. Alex Mustard here: http://www.wetpixel.com/articles/review-nauticam-wide-angle-corrector-port Alex has been so supportive in contributing his time and effort, at his own cost, in field testing 2 different versions of the WACP at various sites during the development of the lens. It was only possible from his personal hands-on experience, and with his extensive knowledge and constant pursue of ultimate image quality, that he can help return his valuable feedback to me for making improvement before the final launch of the product. I would not have been involved in optical design without the inspiration and encouragement from Alex. It has been a most enjoyable journey for myself ! Edward
  3. Hello, The 28mm + WWL-1 has been my only option for wide angle when shooting with a Sony A7 or A9 camera, and I never find I want something else! Here is a link to a gallery of pictures taken in January: https://nauticam.smugmug.com/HousingTests/NA-A7Riii
  4. Hi KL, We revised the internal design in the beginning of 2016. Edward
  5. Hi Dustin, We have revised the design of the Flip Holder some time ago (sorry that I forgot the exact time!) and I believe this problem have been fully resolved as I also dive a lot and I don't experience this problem anymore. I would like to send over 2 of the new ones to you to help testing the new design in the field. Please let me know the best way to get them over to you. Best regards, Edward
  6. Hi Johnqdiver, I am interested. I will be in London mid of June so if you don't mind the delay I can pay you the cash then. Edward
  7. Hello Herve, You really have nothing to worry about the file quality of the Sony RX100iv. If you download photos from our Smugmug site you can look at the Exif data and find the ISO setting of the photos. For example the Whale Shark photo (1st one in this thread) was shot at ISO640, and some other wide angle photos were shot at ISO320. My personal feeling is the files from the RX100iv is even cleaner than the EM5 Mk I. I can usually use 1 battery for 2 dives. Edward
  8. Hi Interceptor, I used the PZ Panasonic 14-42 with a flat port shortened to 29mm. The macro 35 port will fit very well with the new Panasonic 14-42 mark II, and our zoom gear will be shipping soon. I look forward to sending you our lens in less than 2 weeks so that you can experience various aspect of this lens personally (sharpness, contrast, close focus and lack of CA/distortion etc.). Zooming through the lens is no problem. Would it be fine to send the lens to Alex T and let him arrange local delivery? Edward
  9. We received some inquiry recently about whether there is a possible solution for using a wet wide lens with the Panasonic and/or Olympus 14-42mm lenses, and I would like to share some photos I shot with a prototype wet wide lens during a test we carried out in May this year. When working with the 14mm end of the lens the FOV was 120° then and we were able to increase it to 130° now. The entire gallery is here: https://nauticam.smugmug.com/HousingTests/NA-EM5II/
  10. Hi Interceptor, that's good idea. I will arrange a loan lens to you. The first production ones will be available about 2 weeks later.
  11. Thanks everyone for the encouragement and constructive comments! I must say that it means a lot to me for what Alex said about the lens and the photos, from someone who owns so many W/A lenses and has such broad knowledge about photography and optics, and has been judge for so many renowned worldwide competitions. Not to mention having shot and shared so many stunning photos himself. Alex surely gave me much inspiration during our brief meeting in Milan in 2013 discussing future of underwater optics. After several years of full commitment in underwater lens design I can say that no single one lens is perfect, whether it is Zeiss or Samyang, for land or for underwater. So, this Wet Wide Lens is never meant to be perfect. A good lens design is always a good compromise between cost, size, glasses chosen, complexity and ease of production and quality assurance. I hope I have found a fine and reasonable balance this time. For some of the questions: - when used with the RX-100 IV, I had to zoom the camera lens to around 25-26mm equivalent. - Haven't compared image quality with the Inon lens. I hope someone can do that and tell us what he/she thinks. - Haven't tried the white balance capability of the camera. All my w/a photos were shot with Magic Filter at sunlight wb and color corrected in post. - We already tested most versions of Panasonic/Olympus 14-42mm lenses and they all worked with the appropriate ports at all focal lengths. Greetings from Hong Kong. Edward
  12. Many thanks Alex, it actually looks even better on my display with the original file. Developing wide lenses is so hard! This is my fifth design/prototype until I think it is good enough for production, and each round takes 3-4 months.
  13. Had so much fun shooting the new Sony RX-100 IV with our new Wet Wide Lens and the CMC during our Workshop at Club Paraiso, Mactan, Cebu during early August. The image quality with the new sensor of this little camera is just amazing, especially paired with our new lens.

  14. Hi Adam and Phil, The D800 housing was slightly modified by our Japan distributor to use with D810. Even we didn't know of this arrangement as they were under strict NDA with Nikon. I believe an upgrade kit can be built for existing D800 housings, save that the new 'info' button can't be accessed, and certain control may bot be 100% perfect. Edward
