Product Information
The Ikelite 5505 FL Flat Port is a fixed-length flat port built for Ikelite SLR underwater housings, sized to accommodate standard, macro, and telephoto lenses up to 4.5 inches (11.4 cm) long and 3.3 inches (8.4 cm) in diameter.
Who it is for
This port suits underwater photographers shooting with an Ikelite SLR housing who want to use standard, macro, or zoom lenses on small subjects. Because flat ports use refraction to reduce the lens's angle of coverage and magnify the image, the 5505 is a good match for divers focused on macro and close-up work rather than wide-angle scenes.
Key details
- Maximum lens length: 4.5 inches (11.4 cm)
- Maximum lens diameter: 3.3 inches (8.4 cm)
- Port type: Fixed-length flat port, SKU 5505
- Optical effect: Refraction reduces angle of coverage and magnifies the image, ideal for small subjects
If a lens's full length is accommodated by the port, a 1:1 macro lens may vignette when used at infinity. In that case, Ikelite recommends choosing a dome port instead so the lens's full range of focus is usable.
Compatibility and sizing
The 5505 is designed for Ikelite SLR housings and is matched to specific camera and lens combinations listed in Ikelite's FL Port Charts, such as the Sigma 50mm Macro and the Nikon 85mm f/3.5G ED VR AF-S Macro. Confirm your exact lens length and diameter against the 4.5 inch by 3.3 inch limits before ordering.
What's in the box
- Flat port
- O-ring #0105

Frequently Asked Questions
What is the maximum lens size for the Ikelite 5505 flat port?
The Ikelite 5505 flat port accommodates lenses up to 4.5 inches (11.4 cm) long and 3.3 inches (8.4 cm) in diameter. This covers many standard, macro, and telephoto lenses used with Ikelite SLR housings. Always check your specific lens against these dimensions, since lenses longer or wider than this will not fit the port correctly.
What comes with the Ikelite 5505 flat port?
The 5505 ships with the flat port itself, an O-ring (#0105), a neoprene cover (#0200.5), and a 1cc tube of silicone lubricant.
Should I choose a flat port or a dome port for macro photography?
A flat port like the Ikelite 5505 is recommended for standard, macro, and telephoto lenses because refraction reduces the lens's angle of coverage and magnifies the image, which suits small subjects. However, if the port fully accommodates a 1:1 macro lens's length, the lens may vignette at infinity; in that case a dome port is the better choice for full-range access.
Which Ikelite housings and lenses work with the 5505 port?
The 5505 is designed for Ikelite SLR housings and is matched to specific camera and lens pairings listed in Ikelite's FL Port Charts, such as the Sigma 50mm Macro and the Nikon 85mm f/3.5G ED VR AF-S Macro. Check the current FL Port Chart or contact DiveCatalog.com to confirm your exact housing and lens combination.
