Product Information
The Ikelite FL 8 Inch Dome Kit for Lenses Up To 5.1 Inches (SKU 5511.5) bundles the Modular 8-inch Dome with the FL Lens Extension for lenses up to 5.1 inches, creating an injection-molded acrylic dome port rated to 200 feet (60 meters) that accepts wide-angle lenses up to 5.1 inches (12.9 cm) long and 3.3 inches (8.4 cm) in diameter.
Who it is for
This kit is built for underwater photographers running Ikelite DSLR housings with Four Lock (FL) port mounts who shoot wide-angle zoom lenses such as the Canon EF 17-40mm f/4L, Nikon AF-S 18-70mm f/3.5-4.5, or Nikon 18-35mm. The 8-inch dome's larger diameter reduces edge distortion compared to smaller 4-inch or 6-inch domes, and it is well suited to over-under, half-in half-out water shots.
Key details
- Modular 8-inch Dome made of injection-molded acrylic, depth rated to 200 feet (60 meters), weighing 3.9 lb.
- FL Lens Extension weighs 13.5 oz and threads onto the base of the dome for simple assembly.
- Accommodates lenses up to 5.1 inches (12.9 cm) long and 3.3 inches (8.4 cm) in diameter with the dome attached.
- Additional Lens Extensions of varying lengths are sold separately and work with this same Modular 8-inch Dome.
Compatibility and sizing
The Modular 8-inch Dome works with Ikelite's FL and DLM port systems and is also compatible with older two-lock mount housings, but it is not compatible with the newer Dry Lock (DL) port system. A Modular Glass Flat Front can be substituted for the 8-inch Dome, allowing the same FL Lens Extension to be used with compact macro lenses up to 5 inches (12.7 cm) long.
What's in the box
- Modular 8" Dome, product #5510.45, including dome shade, neoprene front cover, and silicone lubricant
- FL Extension for Lenses Up To 5.1 Inches, product #5510.28, including extension body, housing-connection O-ring, front-connection O-ring, and a 1cc tube of silicone lubricant
- Instruction Manual for 8" Dome FL System

Frequently Asked Questions
What size lenses fit the Ikelite FL 8 inch Dome Kit?
With the dome attached, this kit fits lenses up to 5.1 inches (12.9 cm) long and up to 3.3 inches (8.4 cm) in diameter, such as the Canon EF 17-40mm f/4L or Nikon AF-S 18-70mm f/3.5-4.5. If you substitute a Modular Glass Flat Front for the dome, the lens length capacity changes to up to 5 inches (12.7 cm) for compact macro lenses.
Will this dome work with an Ikelite Dry Lock (DL) port housing?
No. The Modular 8-inch Dome in this kit is built for Ikelite's FL and DLM port systems and also fits older two-lock mount housings, but it is not compatible with the newer Dry Lock (DL) port system. Confirm your housing's port mount type before ordering.
Can I use the Lens Extension from this kit with a different dome or flat front?
Yes. The FL Lens Extension threads onto the base of the Modular 8-inch Dome, and a Modular Glass Flat Front can be substituted in place of the dome to pair the same extension with compact macro lenses. Additional Lens Extensions of other lengths are also sold separately for use with this dome.
