The DJI Osmo Action 5 is one of the most advanced action cameras available, combining rugged build quality with impressive video performance. While it can hold its own in demanding conditions, many creators seek ways to expand what it can do. The Ulanzi OA-14 Camera Cage is designed with this in mind. Compatible with the DJI Osmo Action 3, 4, and 5, it provides an extra layer of protection and a host of mounting options that make the camera far more adaptable in professional and creative setups.
For the purposes of this review, the focus will be on how the OA-14 works with the Osmo Action 5. This pairing demonstrates how the cage can transform DJI’s flagship action camera into a more versatile tool, suitable for vlogging, sports shooting, or creating social media content. At 87 grams, the aluminium alloy frame adds minimal bulk but significantly expands the range of accessories that can be attached.
The OA-14 stands out for its quick-release lock, which makes inserting and removing the camera fast and straightforward, while precision cut-outs ensure the Type-C port, battery door, and controls remain usable. It is designed to allow creators to work quickly without having to strip down their setup, making it a convenient option for extended shooting sessions.
Strong and lightweight aluminium design
The OA-14 is built from aluminium alloy, which immediately sets it apart from DJI’s lighter plastic protective case. The material provides a strong, rigid frame that can withstand knocks and drops while also dissipating heat effectively during extended recording sessions. At just under 90 grams, it is surprisingly lightweight for a metal frame, keeping portability intact while offering enhanced durability.
The dimensions (79.8 x 61.1 x 32.7 mm) ensure a snug fit for the Osmo Action 5. Once installed, the camera sits firmly inside the cage, with no unwanted movement. A sponge gasket lining adds stability and prevents direct metal-to-camera contact, reducing the risk of scratches while dampening vibrations. This detail shows Ulanzi’s attention to the practical realities of action shooting.
From a design perspective, the OA-14 is both functional and minimalistic. Its precision cut-outs ensure the camera’s buttons, ports, and screens remain accessible. The aluminium frame avoids being bulky, retaining the compact feel of the Action 5 while offering significantly more security. The camera still looks sleek, and the cage feels like an extension of the design rather than an intrusive add-on.
Importantly, the design keeps the battery door accessible, so users can replace batteries or memory cards without removing the Action 5 from the cage — a convenience for creators shooting long sessions that require multiple power packs.
Features that expand creative setups
The Ulanzi OA-14 distinguishes itself through the number of mounting options it offers. Multiple 1/4-inch threaded holes, cold shoe mounts, and a GoPro-style folding port give users the flexibility to attach microphones, lights, tripods, or grips. This makes it a much more versatile option than DJI’s official case, which is primarily limited to basic mounting.
The quick-release lock system is one of its most practical features. The cage can be opened and closed with a single click, eliminating the need for screws or clamps. This makes it fast to mount or remove the Osmo Action 5, even in the middle of a shoot. The lock feels secure, ensuring that the camera stays in place while in use.
The OA-14 also allows creators to shoot in both horizontal and vertical orientations. This dual-orientation support makes it especially valuable in today’s multi-platform landscape. For example, wide shots can be filmed in landscape mode for YouTube, then quickly shifted to portrait for TikTok or Instagram Reels without needing to rebuild the rig.
Another key functional benefit is the ability to charge the Action 5 while it is still inside the cage. The cut-out for the Type-C port is well-positioned, allowing cables to connect without obstruction. This is ideal for timelapse shooting, livestreaming, or long sessions where external power is needed. Just as importantly, the battery door remains accessible, making battery swaps straightforward, even when the camera is caged.
Day-to-day usability and workflow
In real-world use, the OA-14 enhances the DJI Osmo Action 5 experience for those who want to go beyond simple point-and-shoot usage. Its lightweight means it does not add unnecessary bulk to rigs, whether mounted on a helmet, handlebars, or handheld on a selfie stick. For creators who prioritise protection without sacrificing portability, the OA-14 finds the right balance.
Battery changes are simple, as the cut-out provides clear access to the door, letting users swap power packs directly without removing the camera. For creators who shoot long sessions with multiple batteries, this accessibility is an important advantage over bulkier cages. For those who prefer continuous power through a power bank, the cage also supports external charging without compromise.
On the positive side, the cage opens up creative opportunities. With a microphone and compact light attached, the Action 5 transforms into a full vlogging rig, while still being small enough to carry around easily. Accessory mounting feels natural, with no interference with the lens or rear screen. This makes the OA-14 particularly useful for hybrid shooters who move between action footage and talking-head segments.
The horizontal and vertical shooting flexibility worked as intended during testing. Switching between the two orientations was quick and reliable, making it easy to capture content for multiple platforms without needing to reconfigure the entire setup. For creators who produce both long-form and short-form video, this is one of the cage’s biggest advantages.
How it compares with DJI’s official Action 5 case
DJI’s official protective case for the Action 5 has a different design philosophy compared to the Ulanzi OA-14. It prioritises portability and ease of use, offering lighter protection while keeping all functions unobstructed. For users who mainly need basic safeguarding and very fast access, the DJI case is the simpler choice.
The OA-14, however, is geared toward creators who need more flexibility. Its aluminium alloy build provides stronger protection, and its multiple cold shoe and threaded mounts make it possible to build complex rigs. While DJI’s case is convenient, it does not offer this level of expandability.
Ultimately, the official DJI case is best suited for simplicity and casual use, while the OA-14 is better for creators who want to push their Action 5 further. The choice depends on whether speed or versatility is the higher priority.
The verdict: Ulanzi OA-14 Camera Cage for DJI Osmo Action 3/4/5
The Ulanzi OA-14 Camera Cage is a solid companion for the DJI Osmo Action 5, and while it is also compatible with the Action 3 and 4, it shines brightest when paired with DJI’s latest model. Its aluminium alloy construction offers excellent protection, while its mounting options unlock new creative possibilities.
Battery access is not compromised, as the door can be opened while the cage is on. For creators who rely on multiple power packs, this makes the OA-14 practical for longer shoots. Combined with its support for external charging, the cage ensures uninterrupted shooting even in demanding conditions.
Its quick-release lock, multi-orientation shooting support, and accessory mounts make it far more versatile than the stock case. Real-world use demonstrates that it is well-suited for vloggers, adventure sports enthusiasts, and social media creators who want to maximise the benefits of their Action 5.
For users who want simple, lightweight protection, DJI’s own case will suffice. However, for creators seeking to elevate their shooting setup, the OA-14 offers the durability, flexibility, and creative freedom that make it a smart investment.
