Product Information
The Ikelite 5506.5 is a flat port for Ikelite SLR underwater camera housings, built for standard, macro, and telephoto lenses, with built-in focus gearing for lenses whose focus collar extends beyond the housing's own focus control.
Who it is for
This port suits underwater photographers running an Ikelite SLR housing who shoot standard, macro, or zoom lenses and want to capture small subjects up close. Because flat ports reduce a lens's angle of coverage and magnify the image through refraction, this style suits shooting small subjects with standard, macro, or zoom lenses.
Key details
The 5506.5 is a focus port, meaning it has built-in gearing that lets you control focus on lenses whose focus collar extends past the housing's focus control knob. Because of refraction through the flat optical window, the port narrows the lens's angle of view and magnifies the subject, which is why Ikelite recommends flat ports for standard, macro, and telephoto lenses. One sizing note: if a port is long enough to fit the full length of a 1:1 macro lens, that lens may vignette when focused at infinity; divers who need access to a lens's full focus range, including infinity, should choose a dome port instead.

- Flat port design: Recommended for standard, macro, and telephoto lenses.
- Built-in focus gearing: This is a focus port, with gearing built in for lenses whose focus collar extends beyond the housing's focus control.
- Refraction-based magnification: The flat optical window reduces the lens's angle of coverage and magnifies the image, which suits close-up shots of small subjects.
- Best for small subjects: Ideal when using standard, macro, or zoom lenses to shoot small subjects rather than wide scenes.
- Vignetting note: A port long enough to fit the full length of a 1:1 macro lens may cause the lens to vignette when focused at infinity.
- Dome port alternative: Divers who need access to a lens's full focus range, including infinity, should choose a dome port instead of this flat port.
- Housing fit: Designed as an SLR underwater housing port in Ikelite's lens, filter, and port accessory lineup.

Frequently Asked Questions
Should I choose the Ikelite 5506.5 flat port or a dome port for my lens?
Choose the flat port if you are shooting standard, macro, or telephoto lenses on small subjects, since flat ports magnify the image through refraction. If you need the lens's full focus range, including infinity, with a 1:1 macro lens, choose a dome port instead, since a flat port long enough for the full lens length can vignette at infinity.
What does the focus feature on the Ikelite 5506.5 port do?
The 5506.5 is a focus port with built-in gearing for lenses whose focus collar extends beyond the housing focus control.
Can I use the Ikelite 5506.5 with a wide-angle lens?
Ikelite recommends flat ports for standard, macro, and telephoto lenses; contact us to confirm fit with your specific lens and housing.
What happens if I use a 1:1 macro lens with this port at infinity focus?
A flat port long enough to fit the full length of a 1:1 macro lens may cause the lens to vignette when focused at infinity. If you need full-range focus access on that lens, including infinity, Ikelite recommends choosing a dome port instead of a flat port like the 5506.5.
