Product Information

The Ikelite FL 8 Inch Dome Kit for Lenses Up To 4.25 Inches is a two-piece underwater housing accessory that pairs the Modular 8-inch Dome with a Modular Lens Extension sized for lenses up to 4.25 inches (10.8 cm) long. Built for photographers using Ikelite FL (Four Lock) port system housings with wide-angle zoom lenses such as the Canon 17-40mm or Nikon 18-70mm, the injection molded acrylic dome is rated to 200 feet (60 meters) and weighs 3.9 lb.

Who it's for

This kit is for underwater photographers who already shoot with an Ikelite FL port system housing and want a larger dome than the standard 4- or 6-inch options. The 8-inch diameter reduces edge distortion on certain super-wide angle lenses and makes over-under, half-in half-out compositions easier to shoot. It's a practical choice for anyone using a Canon 17-40mm or Nikon 18-70mm zoom lens, or planning to add other zoom lenses later.

Key details

  • Dome material: injection molded acrylic
  • Dome diameter: 8 inches
  • Dome weight: 3.9 lb
  • Dome depth rating: 200 feet (60 meters)
  • Lens extension length accommodation: up to 4.25 inches (10.8 cm)
  • Assembly: the Lens Extension threads onto the base of the Modular 8-inch Dome

Compatibility and sizing

The dome and extension are designed for Ikelite FL (Four Lock) port housings and are compatible with the Canon 17-40mm and Nikon 18-70mm zoom lenses. Additional Lens Extensions in other lengths are sold separately and can be swapped onto this same 8-inch dome to fit different lenses. A Modular Glass Flat Front, sold separately, can replace the dome entirely if you want to use the Lens Extension with a compact macro lens instead.

What's in the box

  • Modular 8" Dome # 5510.45
  • Extension for Lenses up to 4.25" # 5510.24

Frequently Asked Questions

What lenses work with the Ikelite FL 8 Inch Dome Kit?

The kit is compatible with a variety of zoom lenses, including the Canon 17-40mm and Nikon 18-70mm. The included extension accommodates lenses up to 4.25 inches (10.8 cm) in length on Ikelite FL (Four Lock) port system housings. The 8-inch dome's larger diameter is especially suited to super-wide angle zoom lenses.

Can I use this dome with a different, shorter or longer lens?

Yes. The Modular Lens Extension included in this kit threads onto the base of the 8-inch dome, and Ikelite sells additional Lens Extensions in other lengths separately. Swapping to a different extension lets the same 8-inch dome fit lenses that fall outside the 4.25 inch (10.8 cm) range included here.

What is the depth rating of the 8-inch dome?

The Modular 8-inch Dome included in this kit is rated to 200 feet (60 meters).

What exactly comes in the FL 8 Inch Dome Kit?

The kit includes two components: the Modular 8" Dome (# 5510.45) and the Lens Extension for lenses up to 4.25" (# 5510.24). The extension threads directly onto the base of the Modular 8-inch Dome for simple assembly.
