A macro port compatible with the Canon EF-S 35mm Macro IS STM lens. It is used on its own with the MDX housing. This specially designed port fits very compactly into the housing when mounted.

※Although the M67 thread is present, the lens has a very short minimum focusing distance, so close-up lenses are effectively unusable.

Thanks to specially designed molds and high-precision injection molding, we have achieved a concave meniscus shape with the same precision as an optical lens.
The concave meniscus shape works well with the internal correction lens; when used together, they enable sharp imaging all the way to the edges of the frame without having to stop down the aperture.

By using optical-grade PMMA for the dome, we have achieved a refractive index close to that of glass and high light transmittance. The inner surface of the dome features a 7-layer AR (anti-reflection) coating, which prevents internal reflections—such as the reflection of lens markings—and minimizes the impact on image contrast.

The flange surface inside the port features light-blocking grooves and an anti-reflective coating, providing thorough protection against internal reflections.

*Compatible with all wide-angle lenses listed in the system chart.
*By replacing it with the included NA port bayonet, it can also be used with the N120 port mount on Nauticam housings.
*Port combinations are the same as those for the Universal Dome Port 210/AR.

A versatile port with a wide range of compatible lens diameters. Compatible with both fisheye and wide-angle zoom lenses. When used in combination with the internal correction lens, it improves image quality at the edges. Includes a dedicated port cover and port case.

・Made from BK7, an optical glass with a proven track record
・Delivers high image quality with two types of anti-reflective coatings
The convex surface features a multi-layer AR coating that effectively suppresses flare and ghosting. The concave surface features a SiO₂ coating. This reduces the refractive index of light passing through the glass to 0.01%, thereby maintaining high contrast.

The dome incorporates the new material “PLANEXT®.” Featuring high-precision injection molding and a 7-layer AR (anti-reflection) coating, this next-generation dome port combines excellent optical performance with versatility.
※PLANEXT is a registered trademark of Teijin Limited.

Optical Performance
PLANEXT® is a material that offers optical performance equal to or superior to that of conventional acrylic and optical glass. Using high-precision injection molding, we have successfully manufactured concave meniscus shapes with the same precision as optical lenses. The concave meniscus shape works well with internal correction lenses; when used together, they enable sharp imaging all the way to the edges of the frame without the need to stop down the aperture. Furthermore, despite being a resin material, it allows for a stable AR coating. Combined with the flange’s light-blocking design and anti-reflective coating, thorough measures have been taken to prevent internal reflections, effectively preventing lens markings from appearing in the image and minimizing contrast loss.

Strength Performance
Thanks to PLANEXT®’s superior molecular bonding strength (Charpy impact strength) and newly designed flanges, the pressure rating has been increased from the conventional 80 m to 100 m.

Versatility
Compatible with all wide-angle lenses listed in the port system chart.
※The port configuration is the same as that of the Fish-Eye Dome Port 240.

This Optical Glass port is ideal for wide-angle photography with AR multi-coated digital SLR cameras. Includes a port case and dome port cover.

* Less prone to peripheral distortion (aberration). (Less likely to produce blurring.)
* High light transmittance. Also makes it easier to capture sharp images.
* Less prone to flare.
* Made of glass, so water droplets slide off easily, making it effective for shooting on water surfaces.

Extension Ring with Focus Dial. Enables manual focusing on zoom lenses (with port lock mechanism).

*The Focus Gear FC is required for manual focus shooting (can be used in conjunction with the Zoom Gear).

●This popular short-zoom lens, which previously could only use autofocus underwater, now allows for manual focus shooting while zooming. For example, even if a subject no longer fits within the AF frame, you can make precise focus adjustments without changing the composition.
● This is useful when encountering situations where only manual focus is possible, such as with subjects that are difficult to focus on with autofocus (large, fast-swimming fish or mammals), or in dark environments or conditions with poor water clarity.
● We paid close attention to the length and angle of the dial shaft—which can be accessed while firmly gripping it between your index finger and thumb—as well as its placement to minimize interference with the zoom dial.
