  1. I have been using two Nauticam 2X10 inch (more less) float arms, around 700g (24oz) lift with the Olympus 7-14 zoom, NA-EM1II housing and Zen 200mm port, with two Inon Z-240 strobes. Works for me. For the Olympus 8mm I use the Nauticam 140mm port with 17mm extension with two Inon Z-240's and no strobe arms.
  2. I have used the Metabones adapter with Canon 8-15mm Fisheye zoom and A7R II in Nauticam NA-A7II housing with ZEN 100mm Fisheye port. Auto focus works well and allows for a very small package. As with all fisheye lenses the larger the port the better the corner sharpness. I will send you a PM with a link to some images.
  3. My review is now posted in the new issue of uwpmag.com, this is a free PDF download.
  4. The BOOT show photos of the new E-M1 mkII housing (front and rear of the housing have been shared on my Facebook page, (Phil Rudin) if you have an account and are interested. I am sure we will be seeing more new photos being posted soon.
  5. The Sigma lens compatibility charts don't list the MC-11 being compatible with the Sigma 15mm fisheye or with any Sony or other full frame lens wider that 35mm. As a result I chose the Metabones and Canon 8-15mm zoom with the ZEN Underwater 100mm port with the removable shade for my Nauticam A7R II housing. No vignetting but a bit soft at the edges as would be expected with such a small dome port. I have also used the same combo with a ZEN 200mm port and I don't see much of a difference. You can find some images on my Phil Rudin Facebook page. I also have Sony equipment for sale if you would like to send me a PM.
  6. You may want to checkout this new Pelican hard case which is 40% lighter than past cases and suitable as a carry-on bag.
  7. I know this may seem a bit confusing but first lets revisit your numbers. If you look at the current Nauticam port chart the 12-40 is listed with a 47mm 85-120 port extension and the Olympus 7-14 is listed with the 55mm 85-120 port extension plus a 10mm extension. That makes both within 2mm of each other at 67mm for the 12-40 and 65mm for the Olympus 7-14. I would expect either configuration to work with both lenses and the 180mm port. For the ZEN 170mm port as you say the distance for the 12-40 is 60mm and the 7-14mm is 80mm for the port which is 170mm. This is what you have not factored in, FIRST the Nauticam 180mm port glass sits in a port mount which has about 15mm of extension from the mount to the start of the glass while the ZEN 170mm port mount is about flush with the glass. This difference adds the additional extension for the Nauticam port. SECOND is that the distance from the point of lens to the spot where the virtual image begins is calculated for a zoom lens at its widest angle of view. So 7mm and 12mm. As the 12-40 lens extends to a greater length the dome begins to act more like a flat port as you get close to the glass. Since the 12-40 is about 84mms before being extended and the 7-14 is about 105mm and has internal focus rather that extending is needs to sit further from the port than does the 12-40mm. Because the Nauticam 180mm dome is wider the 12-40 can sit a bit further away from the glass than with the 170mm port. The extensions lengths are about the same but the ZEN port has a flat 120mm opening into the port while the Nauticam port has the same 120mm opening but then angles out preventing vignetteing with the overall longer port. If you look at the two photos you can see the ZEN 200 port on the extensions and the Nauticam 180mm port on extensions with the housing sitting on the tanks.
  8. I don't know what source you are using to compare sensors but that is about as silly as saying that the FF Canon 5D IV sensor has not really progressed much over the 5D sensor or that the $2000.00 Nikon D500 has not progressed much over the $1000.00 D100. I have been shooting with the Sony A7R II for a year and a half now but regardless of image quality which is clearly high by any standard the Olympus system is still makes a better underwater system overall.
  9. My new review for the Canon EF 8-15mm F/4 Fisheye, full review is a free PDF download at uwpmag.com.
  10. Apples to apples Mike, the D500/D750 announced at $1997 and the D810 at $3000 with the Canon 7D at $1800. The E-M1 announced at $1400. and the Olympus E-5 the then top "pro" camera announced in 2010 for $1700. Bitching about the price is quite common with many new camera releases. In the EU the E-M1 II with a select new pro lens like the new 12 to 100 F/4 Pro you get an £100.00 ($125.00) discount. A lot of people complained about the price increase of the E-M1 at $1400 over the E-M5 at $1000.00 and the fact (with E-M5) that you had to buy the camera with the 12-50 kit lens if you wanted to get an early release. The E-M1 II has an excellent set of specs, better than D500 or 7D and most shooters buying the E-M1 II will be shooting the camera both above and below water with lenses like that wonderful 40-150/1.4 tele combo and be able to do it hand held because of the best IBIS in the market. The bigger issue to me is simple, if I am buying a new U/W system all of the components for E-M1 system will be just as expensive as the components for the E-M1 II so I can have a system with the very latest improvements or a three year old version for a $600 difference if I bought the E-M1 new. The other option is that you can always wait another 3-3 1/2 for the E-M1 III which I am sure will be just as expensive or move to another manufacture like Panasonic GH-4 which cost $1700 at release. For those of use who are already invested in an Olympus housing system and glass all that will be required is the new body and basic housing, my bet is that some used E-M1 housings and cameras will be coming to the Wetpixel market place soon.
  11. I own the Sony 16-35mm zoom for my A7R II but I have been using the Canon 8-15mm Fisheye zoom with Metabones IV in a Nauticam housing. Ikelite has a solution as well using the eight inch port in believe. I would be sending Ikelite or your Ikelite dealer an e-mail for the part numbers.
  12. The Olympus PPO-EO1-EO5 ports, the PER-EO2 extension and several gears are carry overs from the Olympus 4/3 format DSLR underwater housings. This is the reason you need the threaded port adapter for them to work with the PT-EP housing line rather than just pushing in like the newer ports designed for M43 PT-EP housings. Ports were also made by Athena, Inon and others for the DSLR line of housings. Olympus is the only camera manufacture that has consistently released housings for their interchangeably lens auto focus housing going all the way back to the E-300. I have included photos of the Olympus E-300 and E-520 housings with some of these ports. The PPO-EO4 port and extension pictured above came with a metal dome shade not pictured above. These were high quality ports and it is nice that Olympus has allowed them to be used with current housings.
  13. Regarding CFWA and WAM photography much has to do with the size of the port since both the Olympus 8mm Fisheye and the Olympus 7-14mm zoom will focus all the way to the port glass. The difference is that one is a 100mm port and the other is 170 or 180mm. See attached photos of the Zen 100mm and the Zen Underwater 170mm ports. The Conch is a CFWA using the 170mm port and the anomie is with the 100mm port. You may also want to consider the Nauticam WWL-1 water contact lens which can be more cost effective, it works with M43 "kit" zooms from both Olympus and Panasonic in a small flat port with 67mm thread. It can be removed U/W and replaced with a closeup lens like the Nauticam CMC-1 & CMC-2, also linked a photo.
  14. My new reviews for the Sony A6300 with Ikelite housing and the Zeiss 18 mm with Zen Underwater 200 mm dome are now posted at uwpmag.com. This is a free PDF download with lost of great articles and reviews.
  15. I expect this lens would be attractive to those shooting Sony APS-C cameras like the new Sony A6300 at half the cost of the Zeiss Touit 50 mm F/2.8. Also as a fish portrait lens for Sony A7 series full frame shooters.
  16. The best suggestion I can give you regarding install of the port is to grease the port threads as well as the O-ring and remove often. I find that the biggest problem with battery power comes when using the 90mm macro. I am getting longer battery life with my wide lenses which include the Canon 8-15 Fisheye zoom and the Zeiss 18mm F/2.8.
  17. Try mounting the extension to the housing then mount the lens to the camera from the front of the housing, then mount the port over the lens onto the extension and reposition the port shade so it will not vignette.
  18. You can look at these and be the judge. I may shoot the lens in a few days with the Zen 200mm dome to see how it looks. Cant get this close with that dome. Most of these shots are very close to the subject. This is also I believe the only full frame system where you can shoot the 8-15 zoom with a 100mm port. From todays dives using the Canon 8-15mm Fisheye zoom, at the 15mm full frame end and the 8mm circular fisheye ends of the lens. Nauticam Housing, Sony A7R II, Canon 8-15mm Fisheye zoom, Metabones adapter, Zen Underwater 100mm port, two Inon Z-240 strobes.
  19. Another combination to add to the list is the Metabones with the Canon 8-15mm Fisheye zoom and Zen Underwater 100mm optical glass dome port. Focuses very close and the small port is excellent for CFWA. Image A7R II, Canon 8-15mm Fisheye zoom, Nauticam housing, Zen 100mm port, two Inon Z-240 strobes.
  20. Hi Alex, The SMC was basically designed for full frame and the CMC was designed for sub full frame and works the best with M43. This is the C/U lens that would be my choice for M43. CMC and CMC-1 are the same thing. The problem with the C/U lenses is that many people use the lens before they have reached 1:1 with the 60 and other macro lenses. As a result I see images of animals much larger than the 17.2mm X 13mm life size of the m43 60 macro lens. So as Bill has said in the hands of someone who knows how to use the C/U lens you can get excellent magnification but many are using like a placebo only think they are getting higher magnification. These are images I have posted here several times, the configuration is EM-1 60mm macro manual focus to 1:1 (life size) then move the housing until in focus. First is the 35mm slide as a frame of reference, the 60mm life size and then 60mm at life size plus CMC. As you can see a very small final image taken a less than 10mm and very shallow DOF. Most people are not getting this close even when they use a C/U lens. So you can see full frame life size and the final eye image and make your own evaluation of how close that comes to 7:1 magnification.
  21. I have found that this lens becomes more user friendly after a few outings. I use the 0.5 to 1:1 focus limiting setting when using the lens as most of my subjects of choice seem to fall within this range. I also use the Nauticam SMC-1 with this lens. I will be using this equipment in the Philippines next month along with the new Zeiss 18mm and a Canon 8-15mm fisheye zoom.
  22. My Ikelite Sony A7R II review is now posted in the current issue of uwpmag.com this is a free PDF download during the issue run.
  23. I used the standard eight inch acrylic dome port and a short extension, don't recall the part number. For the 16-35 zoom a longer extension is required and I think that part number is in my review. I would like to see a smaller port configuration like maybe a six inch dome or an adapted ZEN Underwater optical glass port for fisheye lenses. Rokinon/Samyang has just announced a 14mm auto focus lens, their first designed specifically for the Sony FE not a DSLR lens with an extension like the current 14mm manual and my 12mm manual focus. I am eggier to see how this lens will adapt using a dome in the 180 to 200mm range.
