TELESIN Waterproof Dome Port for DJI Osmo Action - Split-Level

In this review of the TELESIN Waterproof Dome Port for DJI Osmo Action cameras, the bottom line is clear: this accessory is aimed at hobbyist and enthusiast underwater shooters who want reliable split-level or over-under images without fuss. The dome port moves the waterline away from the camera lens to capture aboveandbelow frames in one shot, and the all-in-one polycarbonate housing with included floating handle and accessories makes setup straightforward. For anyone using an Action 3, Action 4 or Action 5 Pro with a wide-angle lens, this accessory simplifies underwater photography while reducing risk of leakage from multi-piece assemblies.

Key Features

• Designed for Osmo Action: The dome is optically matched to DJI Osmo Action 3, 4 and Action 5 Pro lenses to deliver accurate wide-angle imagery without trial-and-error alignment.
• Above/below shooting: The semi-hemispherical dome moves the waterline away from the lens so you can capture immersive split-level photos and videos in a single frame.
• High transparency materials: Made from PC and acrylic for clear vision above and below the surface, helping preserve color and detail in photos and footage.
• One-piece waterproof design: The integrated polycarbonate body and housing reduce the number of assembly points and lower the chance of leakage compared with multi-part setups.
• Floating grip and strap: The updated handheld floating grip is rubberized for comfort, stores small items, and includes a 1/4' screw hole for mounting options while preventing loss in open water.
• Complete accessory kit: The package includes anti-fog inserts, wrench, cleaning cloth, spare screws, trigger shutter, wrist strap and a soft velvet pouch for transport and maintenance.

Who It's For

The dome port suits recreational divers, snorkelers and beach photographers who already own a DJI Osmo Action 3, 4 or Action 5 Pro and want to create striking over-under photos without complicated optical rigs. It is especially useful for wide-angle shots where the contrast between water and sky is part of the composition.

It is less appropriate for professional underwater cinematographers who require custom optics, interchangeable ports, or deep technical control over lens correction. Those needing housings for very deep technical diving should look for purpose-built cases rated for specific depth limits.
