In Topic: Ikeite A7RII housing and FE28/2 with SEL057FEC converter

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.

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.

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.
