In Topic: Fisheye with Sony a7Rii

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.

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.

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.

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.

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.
