  1. I have had good success with the Sony A7 in Nauticam with 15mm Nikonos adapter ... razor sharp, pretty much always in focus. Relatively small package. ian
  2. Thanks Bernie:) It is a beautiful piece of glass. ian
  3. Thanks guys.... kicking myself for selling one a year ago. It’s how we become pack rats, never sell anything, you might need it. And then you do....
  4. Hello all, Today I have for sale a Seacam modified Nikonos RS R-UW 20-35mm f/2.8 zoom. As you well know, water contact optics are the Holy Grail for corner sharpness, especially with rectilinear wide angles. Beautifully executed by Seacam in Austria. In perfect condition, optics flawless. Works perfectly in Seacam housings. $2000 USD plus shipping As always, my sales are straightforward and worry free. Located in Vernon BC, Canada ian
  5. Hello all, For sale is my very nice Seacam Silver housing for D800 and D800e cameras. This has served me well, been very well taken care of with only a few scratches on the base (Picture 3). Always maintained and never flooded. The housing went back to Seacam in Austria for a full rebuild last year and has one dive trip on it since then. While there, I had Harald replace the rear plexiglass window. I also had him drill and tap a hole on the top to accommodate the Seacam vacuum fitting (Picture 4), in the same location as the fitting on the D500 housing. Much more convenient than the fitting on the lower right side by the handle. Vacuum kit included. At that time I replaced the handles with the smaller set, which improved the ergonomics for my standard sized hands. The electronics have been changed to dual fiberoptic bulkheads with fibreoptic TTL controller from Pavel at UW Technics (Picture 5 and 6). These replace the S6 bulkheads and Seacam controller board, which will be included. The standard Seacam Pro viewfinder is in place. A front body plug is included along with the small maintenance kit from Seacam. ULCS Dovetail plates mounted. Asking $1850 USD, plus shipping. Flawless Seacam S10 viewfinder added for additional $800 USD. Will only sell this separately if housing sells. Pictures available. 2 D800e bodies available if interested separately, both in excellent condition with low shutter counts. As always, my sales are straightforward, and 100% reliable. Thanks for looking Ian
  6. Looking to buy port adapter for Nauticam housing to use Seacam ports. ian
  7. Walt I had the same question a few years ago and was unable to find any answers... so I swallowed hard and pulled the trigger. The answer is YES, it works fine. I used the RS 13mm with a D800 in a Nauticam housing with a port adapter. It works perfectly, mechanically and optically. Never happier with the result!! Until I converted the 20-35 RS lens:( Despite many attempts and $$$ I was unable to adapt the zoom gear to work in the Nauticam. Reluctantly, I sold the Nauticam setup and bought a Seacam for the D800. Both lenses work flawlessly in that setup, but I miss the practicality of the Nauticam design. So, in short, It works just fine with the setup you propose. Harald is very easy to work with through the process, but it aint cheap!! ian
  8. Agree with the Scubapro Go travel fin sentiment ...very comfortable, indeed. Only negative....Maybe a little lacking in power if needed.
  9. Thanks Chris I purchased a pair of NEC PA302W monitors. Calibrated beautifully and are identical to one another afterwards. One dead pixel near the edge of one of them. I got them for a great price from B+H camera in NYC. Lack of 4K NOT a problem Couldn't be happier for my needs:))) ian
  10. Thanks for the input Chris. The NEC is one of the monitors on my short list. Looks as good as the Eizo, but less money. Still not cheap, and not 4K. Not sure if the 4k piece is important? BenQ comes looking good on paper with it's higher end models, but I do have some concerns about build quality and sample consistency. I also do medical imaging to pay for all this, and need the monitors to be DICOM compliant, which the NEC is. It might be my go to:) ian
  11. Hello all, I hope this is the correct forum for this discussion:) I am looking for advice on a new pair of monitors for photo editing, no video. I currently have a 2010 Mac Pro setup with an AMD Radeon HD 7950 3072 MB video card. CPU has been upgraded to 12 core 3.33 gHz. I am using Lightroom and some Photoshop. I have a pair of now ancient Apple 30 inch Cinema displays which are losing brightness. They have served well, but are getting tired. I am considering Eizo, NEC higher end monitors, but open to suggestions. Do I need 4K monitors? I will probably replace the Mac Pro if Apple gets their act together in 2019, although, for what I do, I have no real complaints with my existing tower. I just upgraded it to OS Mojave, so nine years on, it is still current!!! ian
  12. Fred Look What I found:) nikonos 15mm service manual.pdf Hopefully you can download this. If not, send me an email at ianmarsh@icloud.com and I will send the PDF to you ian
  13. Hello Fred I have no additional information on the first generation lens. However, looking at photographs the knobs look the same, although both are silver. I have a Nikonos 15mm ver2 which I have as a parts donor. Send me a PM and I will donate the knobs, control shafts and screws for your project. You could then drill out the seized ones and hope for the best! I don't have o rings, but there is a fellow on Ebay in France who sells them. https://www.ebay.com/itm/Nikonos-II-III-IV-V-O-RING-LENS-28-35-80mm-internal-for-repair-button-glass/253127941546?hash=item3aef99ddaa:g:m6oAAOxyVLNSy7ZF ian
  14. I have been using Lanocote on threaded metal fasteners. It is basically a waxy material made from lanolin and seems to work like a charm preventing galvanic corrosion. You can buy it from boatyards for marine hardware and Backscatter stocks it. ian
  15. David I used Seavison in San Diego. They did a great job; distance correction upper, plain glass lower. Find a mask with tall lenses (e.g. Scubapro Spectra) to give more real estate. I also had them bevel the lower edge of the upper corrective part, so looking downwards I am looking along the bevel, rather than across a flat, distorted transition. It gives the impression of no correction and makes more of the surface useful for vision. ian
  16. Thanks for this! Comprehensive and excellent review tutorial for those of us who are not in the sea every day. Great refresher before the next trip. ian
  17. Thanks all Just got out of the pool Tested with SD, +/- 20mm extension, +/- +2 diopter Looks sharpest with 20mm extension and no diopter. ian
  18. The Superdome is sold:) Thanks for looking ian
  19. To all Thanks for the insight:) ian
  20. Thanks Walt, That is very helpful, indeed. Do you recall if you used a diopter? I'm guessing yes. I am going to use it with a superdome, so hopefully it will be a little sharper at the edges. Thinking it should also be good for splits. I will try it in the pool once I sort the diopter issue. ian
  21. Hello all I am wondering if anyone has actual UW experience with this lens. I have owned it for years and have never taken it underwater. It generally gets mixed reviews topside. I am thinking Seacam Superdome. Any suggestions on diopters or dome extensions? I have recently bought the Nikon 8-15 FE and will be taking this and the dome to Kimbe. I though this would be a great compact topside lens that could be pressed into UW service if suitable. ian
  22. Price Drop: $750 USD, Shipping included in North America. Ian
