  1. I would advise you to consider a separate investment for above water video lights. I have a pair of 2000 lumen lights that I use for mountain biking. They are not fully waterproof but they do not suffer from overheating and have decent burn times. I purchased mine online from Chain Reaction Cycles: https://www.chainreactioncycles.com/ca/en/lifeline-pavo-2000l-front-light/rp-prod161245
  2. Just to close the loop on this thread, I would like to confirm that Ikelite has provided a new port recommendation for the Panasonic Lumix G Vario 12-60mm f/3.5-5.6 ASPH POWER O.I.S. lens for the DLM/B system. This involves the 5516.16 3.75” Extended Dome Port and the new 5515.28 Zoom Gear. This configuration provides zoom through the full range with no vignetting and improved corner sharpness as compared to the 5516.15 port. The zoom gear is currently available from Ikelite but is not yet listed on their website. I expect that it will be a few more weeks before it is listed by retailers but could probably be obtained by special order.
  3. Thanks Swift! I am going to try my luck on Nudibranch Central.
  4. Hi Chris, That was my thinking as well. Today, I was able to obtain a 5516.15 port and test it with my Lumix 12-60mm (the kit lens). It showed no vignetting at 12mm when I used it above water. I was not able to test it in water but I assume that the results would be the same. I suspect that the Lumix 12-60mm may have been tested with the 1” extension, which is how the Leica 12-60mm is configured. I notified Ikelite and asked if they could validate this and, if correct, update the DLM/B chart. In my view, the G85 housing would be more appealing to potential customers if they knew that they could use their kit lens in the cheapest dome with zoom while getting the benefit of dual IS. Cheers, Doug
  5. Hi Chris, This makes sense to me. John at Ikelite suggested that the Leica 12-60 would probably fit in the 5516.17 port with no extension but he could not assure me that it would not vignette. I would need to send him a copy, which I don’t yet own, for testing. I am also confused at his statement that the smaller Lumix 12-60, which I do own, did not vignette in the 5516.16 port, which is 0.375” longer than the standard 5516.15 dome. According to the DLM/B port chart, the Lumix 12-60 vignettes tremendously in the 5516.15. How could a longer port address this? Ultimately, I would be happy using either one of these lenses but I am getting flummoxed by the lack of clear information. Thanks, Doug
  6. Hi Chris, Thanks very much for your thoughtful response. I was also of the understanding that the vignetting was caused by the port being too long. I still don’t understand why Backscatter recommends the use of a diopter with many of lenses in DLM/B ports. In my discussions with Ikelite, John mentioned that they tested the Leica 12-60 before the company developed the shorter 5516.16 and 5516.17 ports. However, since they no longer had the lens, he was not able to test it. He offered to do the testing if I sent him my own lens, but I have not yet purchased it. He also did some testing with the Lumix 12-60 and found that it does not vignette in the 5516.16 port. I have considered the Oly 12-40 Pro and the Oly 12-45 Pro but I would lose the advantage of dual IS, which is important to me for run-and-gun shooting. Also, the Leica 12-60 has greater reach and a higher magnification ratio, which are also important to me for semi-macro. Note that I have purchased all of the gear for the wide and macro configurations but I have not yet purchased anything required form the standard zoom. I do own a copy of the Lumix 12-60 kit lens so I could always use that in the 5516.16 port. That said, my preference is to use the Leica 12-60, which is faster, sharper and has a slightly higher magnification factor. To this end, maybe I should reframe my question as follows: Is anyone aware of a port/extension combination that will allow the use of the Leica 12-60 in an Ikelite DLM/B housing? Thanks, Doug
  7. Hi all, I am currently on my way to upgrading to a mirrorless system based on the Panasonic G85 in an Ikelite DLM/B housing (6961.08). I am already equipped for wide angle using the Olympus 8mm fisheye in an 8” dome port (5516.81) and for macro using the Olympus 60mm macro in an extended flat port (5516.50). My mid-range, run-and-gun option is the Panasonic Leica 12-60mm in a 6” dome with zoom (5515.15) and a 1.2” extension (5516.65). Unfortunately, according to Ikelite’s DLM/B port chart, the 12-60 will slightly vignette at 12mm. I spoke with John at Ikelite and, although he was extremely helpful, he was not immediately aware of a port/extension combination for the 12-60 that would not vignette. That said, Backscatter recommends the use of a +2 close up lens with this configuration. I understand that the principle of a low-strength diopter behind a dome port is usually to improve corner sharpness by moving the virtual image closer to the lens. However, my questions are as follows: 1. Is the addition of a diopter likely to remove the vignetting? 2. What will be the impact on field of view? Will I still get 12mm? 3. Will I still be able to focus to infinity? 4. Can I use step a down ring with a diopter, without impacting image quality, if I want to fit it to a smaller lens? 5. Are there other options to address vignetting or do I just live with a slightly crippled lens at wide? Thanks in advance for your kind assistance and advice! Doug
  8. Hi all, I would appreciate your assistance in identifying what I believe to be some type of juvenile gastropod or bivalve. This was found in Roatan, Honduras underneath a piece of wood at 15 feet. Length is approximately 6mm. Thanks in advance for your help! Doug
  9. I am coming late to this thread but I thought I would throw in my 2 cents since I have relevant experience. I have been using an LX100 in an Ikelite housing for the past three years and I have been very satisfied. I was initially attracted to the LX100 for its M43 sensor, awesome Leica lens, 4K video capability and ability to manual white balance. I also considered the RX100 Mk 3 but was put off by its inability to MWB without a filter and overheating issues (note that these issues have been addressed in later models). The LX10 was not out at the time but in retrospect, I still would have purchased the LX100 due to the larger sensor and faster lens. I went with an Ikelite housing for reasons of cost and I have found it to be just fine for my needs as an amateur. I am sure that the ergonomics of the Nauticam are far superior but it is in a much higher price range. This is compounded by a complex and expensive three-port system, which seems to defeat the simplicity and utility of a point and shoot. For lights, I have a pair of Scubalamp V4K Pros for portraits and two BigBlue ALX2600 for macro. I like the Scubalamps but I regret that I did not spring for the V6Ks at the time. The BigBlues are serviceable for macro but are very cold and are only 80 CRI. I will eventually upgrade both. Over time, I have added on a WD-4 wet lens for shooting wide as well as a CMC-1, two UCL165-M67s and a custom flip holder for macro. I mainly use the CMC-1 but I do stack all three lenses for very tiny stuff. I also made a DIY quadropod using ball arms for improved macro stability. The main limitation of the LX100 is macro due to the comparatively low magnification ratio of the lens. Since this has become a primary interest for me, I am currently upgrading to a mirrorless setup that will leverage the Olympus 60mm macro. You can see some of my footage on my YouTube channel which is linked in my signature block. Happy to take any specific questions on my setup if it is helpful.
  10. I have an LX100 and I use a CMC-1. For subjects less than 5mm, I stack one or two UCL165-M67 for increased magnification in the centre at the cost of increased distortion in the corner. I have a friend who stacks two CMC-1’s for better optical results. If you have already arrived at this point, you will have reached the limits of the LX-100’s macro capability. You can get marginally better macro from the RX-100 or G7X or consider upgrading to a mirrorless setup with the Olympus 60mm macro.
  11. Thank you both! And, thanks for the tip, Massimo. I will look for a copy of Jeff’s book.
  12. Hey all, I am just bumping this thread to let you know that my video won the April 2020 monthly video contest at Scubaverse. It was a pretty tough field with 19 entries, many of which were much more technically proficient than mine. It seems that I scraped by on the strength of my script and narration. The rundown on all the films, including mine, is at the following link: https://www.scubaverse.com/april-2020-video-contest-winner-and-review/ Cheers, Doug
  13. I just realized that I linked the wrong video in this thread. The following is the correct link.
  14. I produced this video to support the daily operations of Bay Islands Reef Restoration (BIRR). Located in Roatán, Honduras, BIRR is a coral nursery and coral restoration program dedicated to conserving and restoring threatened coral species. BIRR is supported by the Roatán Marine Park, Subway Watersports and Turquoise Bay Resort. The primary use of this video is to support pre-dive briefings for scuba divers wishing to assist in the maintenance of coral nurseries and/or outplanting coral fragments on the reef. It may also used to support the PADI Bay Islands Reef Restoration Diver Distinctive Specialty course, which was developed and is delivered by Tripp Funderburk, the founder and chief administrator of BIRR. My wife and I first learned about this project last summer when we took the PADI Reef Restoration Specialty course with Tripp. We were so impressed that I offered to make this video to help streamline the daily pre-dive briefings that he was delivering to students and guests. I hope that my small contribution will help with the long-term success of this important initiative. This video is available for limited use by marine parks, coral restoration projects and dive operators supporting coral restoration operations at no fee. Please feel free to contact me directly to obtain a limited license agreement. All footage in this video was shot on a Panasonic DMC-LX100 in an Ikelite housing and was edited in Davinci Resolve 16.
  15. Hi Aaron, Sounds good! I will send you my details by PM. Cheers, Doug
  16. Hello, I don’t need any of the sync cables. Would you consider $800 plus shipping to Canada for the two strobes, diffusers, chargers and extra battery? Thanks, Doug
  17. Hello, I could use the sync cable, assuming that it has Ikelite connectors at both ends. Would you take $50 plus shipping to Canada? Thanks, Doug
  18. On our March 2020 trip to Roatán, we were joined by our niece who successfully completed her Open Water certification. We also hosted a family of four Open Water divers, who are good friends of ours from back home. Unfortunately, the diving conditions were not great with extremely high winds, waves and surge. The visibility was the worst that we have ever seen with a lot of particulate in the water and generally poor lighting. Macro conditions were also suboptimal due to the strong surge. To make matters worse, I lost a full day of diving to food poisoning and then came down with a bad case of Dengue Fever, two weeks after getting home. At least it wasn't Covid-19! Please also note the special message at the end of this video. Our reefs are currently under threat of overfishing due to the Covid-19 lockdown. The Roatán Marine Park is working closely with local dive shops and the Honduran Navy to step up marine patrols but their resources are limited. If you want to help protect the natural beauty of our reefs, please consider making a donation to the Roatán Marine Park at www.roatanmarinepark.org. Thanks to Danny and Mia at Barefoot Divers and Rino at Jackson's Dive Centrer for the great dives!
  19. Nice, Craig! Love the composition on the third shot. Is that Calvin’s Crack?
  20. This was my first project using Davinci Resolve and the editing and colour correction tools are so much more powerful than Premiere Elements. I still have lots to learn but I feel that this was a big step forward for me both technically and artistically. I appreciate the feedback!
  21. Here is the video from our last trip to Roatán in January 2020. We had an amazing time diving with Barefoot Divers, Roatán and Jackson's Dive Centre. This video is a bit of a departure from my usual fare. Through our time in Roatán, we have become acutely aware of the precarious state of coral reefs as a direct result of climate change and other human-related stressors. As such, I feel compelled to share what we have learned and the dim future that may lie ahead. I would like to make special mention of the Roatán Marine Park and Bay Islands Reef Restoration for the excellent work that they continue to do to support these fragile ecosystems. Please share with your friends and do your part to save our coral reefs.
  22. Thanks SwiftFF5! I spent a few days on dedicated critter crawls so I got more macro footage than usual. I did a couple of dives with Rino Jackson at Jackson’s Diver Center and he found a ton of stuff that I had never seen before. I also did some solo diving in Brick Bay and found a lot of interesting critters on broken sea fans and other detritus. We are booked to return in early January and early March. Hope you have a great trip!
  23. In July 2019, we spent two glorious weeks in Roatán with no kids, diving the South Side with Barefoot Divers, the East End with Dive Pangea and the West End with Jackson's Dive Centre. We logged 15 dives at a variety of sites that included Tortuga, Calvin's Crack, Coco View Wall, Labyrinth, Dolphin's Den, Jumping Jack, Divemaster's Choice and the Barefoot Palapa, among others. We also enjoyed a dive at our very own site, named D2T after the divers in our family (Doug, Deb and Téa). The site is halfway between Lita's Hole and Shark Bait Shallow at the entrance to the Mahoghany Bay inside channel. All underwater video was shot on a Panasonic DMC-LX100 in an Ikelite housing and all topwater video was shot on a GoPro Hero 7 Black.
  24. I may be interested in camera body and housing. Please PM your best price shipped to Ottawa, Canada. Thanks!
