Canon EF 8-15mm Fisheye // Ikelite 200DLM/D Underwater Housing Assembl

If you're looking for the ultimate in wide angle, take a look at the Canon 8-15mm Fisheye lens. Now, as you've heard me say before, I love the Tokina 10-17mm Fisheye. But the Canon 8-15mm Fisheye, while a little bit more expensive, is going to be wider and it's going to perform better since it is a Canon lens in the Canon ecosystem.

John Brigham shows you how to install the Canon 8-15mm Fisheye lens for use with an Ikelite 200DLM/D underwater housing.

EF to RF Adapter

This Canon 8-15mm Fisheye is the Canon EF series, which is the previous series and not the R adapter. Unfortunately, for the time being, Canon has not released a RF mount for the fisheye lenses, so we will use this one. To do so we will need an EF to EOS R adapter.

Remove your back cap, align the red dots and then bayonet the adapter onto the lens itself. In order to accommodate the port we will have to remove the lens hood as well before installation.

Installing the Gear Sleeve into the Housing

Remove the body cap from the camera, take the friction fit gear sleeve and drop it into place so that the teeth sit on the outside rim of the port opening.

Installing the Canon 8-15mm Lens onto the Camera

Now, guide the lens down in through the port opening and onto the camera. Try to make sure that the protrusions don't hit the friction pads and then simply bayonet the lens onto the camera body. You can take your gear sleeve and twist it to confirm it is properly zooming the lens.

Installing the Dome Port

Next, take a little bit of the Ikelite lubricant between your finger and thumb - a very small amount is sufficient. Apply it to the o-ring around the port opening; as you apply the lubricant, you're going to check both visually and tactilely for any debris that may affect the seal.

Take your port and make sure that all three thumbscrews are backed out and free of the inside diameter. Run your finger along the sealing surface of the port checking for any hair or debris that may affect the seal.

Place the port onto the housing with the drive gear positioned on your left hand side. Press down to seal the port and tighten the three thumbscrews. Make sure that the drive gear is interfacing with the sleeve.

Now you're able to shoot the Canon EF 8-15mm Fisheye lens in a DLM/D style housing. Need some more guidance on installation or photo advice from a pro? Reach out to our team today!
