  1. Hello All... Just a note to say I purchased a couple of Seacam items from Vladimir222 without incident. He was not on Wetpixel at the time, but the transaction was honest and up-front. He is new to the community. Language was challenging at times as he doesn't speak English ( and I don't speak Russian), but with patience, it all worked out. ian
  2. Hi I've got one you can have. PM me with your mailing address. ian
  3. Hello All, For sale today is a Sigma 15mm Diagonal Fisheye for Nikon F mount. For full frame Nikon cameras. Pretty much the standard fisheye for underwater use. In perfect condition, with all packaging. Only ever used in a housing, so well protected. You all know what this is and what it does. $450 USD. I will pay shipping in US and Canada. Located in Vernon BC, Canada ian
  4. Hello all, Up for sale is an essentially brand new Nikon D5, Dual XQD slots Purchased in Canada, includes box and all contents of a new camera. Warranty not registered, sales receipt from Henry's Camera in Toronto included. Shutter count is less than 20. I bought this to replace my D4, used to photograph freestyle skiing.

So, I will have little opportunity to use this amazing camera as it is meant to be used. Phantom Glass Screen protectors. Camera is in PERFECT condition. I will pay shipping within Canada and USA Pictures available on request. $5500 USD firm Contact at ianmarsh@icloud.com, or through the forum. Located in Vernon, BC Canada ian
  5. Hello all, Just for fun, I thought I'd try some pool tests of Retra TTL using a UW Technics board in a Seacam housing. To be fair, the Retra is not profiled for this board, so I set the board on Setting1, which is the profile for S+S YS-D1, and Inon Z240. This was suggested by Pavel. Test conditions were: Pool, very dim ambient light 1/125 sec, ISO 100 and 400, Aperture f2.8 - f32, Measured distance 0.75 meter, Nikon D800e with Nikon 105 Macro G lens, Seacam Silver housing, UW Technics finer optic bulkheads UW Technics controller Position #1 Rear curtain flash Analysis: The point of this exercise is to compare Retra TTL to baseline (YS-D1) 1) Not sure what happened with the first two frames of the Retra ISO 400 test. Didn't spot this in the pool. Maybe too trigger happy? 2) The system works well enough for Retra using these parameters. It should get you in the ball park for macro at ISO 100. 3) ISO 400 is more variable on both strobes. It's all over the place with Retra. 4) It is within the range of what Lightroom can cope with. 5) Best at apertures f8-f22, probably the sweet spot. 6) I would probably add +0.7 eV of compensation I would use it on a shot where you might not get a second chance...certainly better than my best guess! I haven't tried Reta TTL on wide angle. Overall, it's pretty good:) Maybe Pavel will write a firmware update for this strobe? (Hint, hint) ian
  6. Jack, Nicely done. Very nice images, indeed! Any massive UW difference over D800 or D810 in your opinion? ian
  7. Hello all, Up for sale is a Nauticam to Seacam port adapter. In perfect condition. Allows you to use your Seacam converted 13mm Nikonos RS with a Nauticam housing... with excellent results! Photos available if requested. (Stock image attached) $100 USD plus shipping Located in Vernon, BC ian
  8. One other thought... I have some experience with the Nikonos RS 20-35mm Seacam conversion. Initially, it had it's detractors who didn't feel it was that useful. 20mm was just not wide enough. (Stephen Frink seemed to do OK with it in the '90's:)) There is some truth in that, but for the right subjects, I was very happy with the results. The small(ish) form factor and razor sharp corners were excellent. Also, unlike the 13mm RS conversion, the original lens is NOT selling for $3500+ USD. It is much more "affordable" than it's upscale cousin. Of course, this also assumes a Seacam housing. The zoom gear is integral with the lens, and despite numerous attempts, I was not able to make it work in a Nauticam housing, which the 13mm will. So, now I have a Seacam housing... I have now pared my UW lens collection down to the Nikonos RS 13mm, RS 20-35mm, Nikonos 15mm on Sony, and Nikon 105G for macro. The only thing I can't do is under/overs. I am completely satisfied with my setup. Now, if I were just a better photographer... ian
  9. Thanks to all interested parties... The viewfinder is SOLD:)) Thanks Bernie!
  10. Hello all, Just back from 12 amazing days aboard the Bilikiki in the Solomons. Absolutely amazing dive trip! Best trip since beginning the Life Aquatic in 1972:) The only issue with the trip is we arrived a few days after the coral spawn, and at times backscatter became an issue. But there were a lot happy animals around! Amazing guides on the boat. Thanks Tina and Oli:) Headed away with all new camera set-up (to me) including a shiny new pair of Retras with a Seacam-D800 and UW Technics TTL board. The strobes were fantastic! Beautiful quality of light, easily controlled and lots of it if needed. As noted by others, it allowed you to focus on the viewfinder instead of the knobs. Battery life with Eneloop pro's was excellent. At least 3-4 dives before i would swap out batteries, mostly out of habit. They were robust, and with the provided (thick) neoprene jackets, were neutrally buoyant and out of harms way. TTL was difficult to sort out because the UW Technics board was not calibrated for these strobes. They did mostly work on the YS-D1 setting, but not at aperture extremes, so I mostly shot manual, which wasn't an issue. I had contacted Oskar 10 days before leaving, and he had the strobes in my hands in good time. Excellent customer service, feedback and followup. All in all, I am very pleased with these strobes. I dove with full confidence they would not let me down. ian
  11. My 2 cents worth on Retra: I emailed Oskar last Sunday, he answered within 10 minutes. Strobes shipped Tuesday from Slovenia, in my hands in British Columbia by Friday afternoon. All safe and sound Strobes are a beautiful pieces of elegant design. They look very robust. Tested out S-TTL protocol with UW Technics board (Thank you Pavel!) for Seacam. Testing done in air. Strobes respond MOST like Z240 YS-D1 setting (position 0) on UWTechnics board. YS-D2 position (position 2) on board overexposes in the middle apertures. Position 1 and 3 grossly over exposes. Can't say enough about Oskar and his company!!! Will wait and see about durability, but feeling very confident ian
  12. Good pickup:( Thanks:) Price Drop: $925 USD for the pair, I'll pick up the shipping. ian
  13. Not a Wetpixel issue, but... Watch out for a listing on Craigslist Newcastle UK for a Nikonos RS kit including 13mm fisheye. He claims his name is Alexander Weiss. He did send additional requested pictures, so probably actually has the gear. I foolishly sent a bank draft for $2200 Cdn and received nothing for my troubles. That was 8 months ago. I see the listing is up again. The listing moves around Britain. It was in Glasgow when I first found it. I started a police investigation through the RCMP and Greenock police, but nothing has come up. Caveat emptor!! ian
  14. Hello All For sale today are two brand new YS-D2 strobes, complete with packaging and all included accessories. These strobes have never been used, and opened only to photograph them. They are 100% functional, with no issues. Have moved to Seacam platform. They are located in Vernon BC, Canada. $1000 USD for the pair. Save about $120 over best price on Ebay. See my previous Wetpixel classifieds for feedback. ianmarsh@icloud.com ian
  15. Price drop! $550 USD Will include shipping at that price. ian
  16. So..... D850 in Seacam D800 housing... complete and utter fail! No big surprise here, but the threaded tripod mount is not even in the same place. Never had a chance:(( ian
  17. Gui There is one on eBay in Holland. http://www.ebay.com/itm/SeaCam-Nikon-D810-Underwater-Housing-SUPER-complete-package-/282553937748?hash=item41c986ef54:g:x3AAAOSwFqNZWVQV ian
  18. Agree with all of the above I purchased two YS-D2 strobes three months ago for a big upcoming trip. I am very apprehensive about even taking them... way to go Sea And Sea. What was I thinking? Now they release a new version that is actually supposed to work properly. I agree. There should be a recall on all Black Sea and Sea YS-D2 and replace them with the new version, no questions asked. I am toying with the idea of taking my old Nikonos SB-105 instead. I KNOW they work. ian
  19. Thanks Alex Let's see if I understand this: The Nikonos RS 13mm is a fisheye, so not really fair to compare to the WACP which is rectilinear. I guess one thing to keep in mind is that the focal length quoted on the lens barrel is the "true" focal length, in air. This is a physical property of the lens construction. The actual focal length in use (underwater) must be multiplied by 1.33. This also changes the FOV of the lens. I had long assumed that Nikon would have originally quoted the focal length (and therefore FOV) on the Nikonos RS and 15mm as the focal length in their native medium (water), since the lenses where designated as R-UW, and don't focus in air. I guess that is not the case. I am assuming this does not happen with the WACP, and in fact, just the opposite. Because of the "Correction", the field of view is increased, at the same time "repairing" the damage done to the corners of the image due to refraction (CA) and curvature of field (DOF). That's got to be some fancy physics. As you said... "You CAN have your cake, and eat it too". That doesn't often happen in the real world:) ian Thanks Ryan.. I just spotted your response while I was typing:)
