The screen is fine, but the lens cover? Shattered. Now what? This is a scenario more action camera users face than you’d think. Whether you’re shredding down a mountain, racing FPV drones at breakneck speeds, or just filming your weekend adventures, one thing is certain: your camera’s lens is vulnerable.

And at under $30, it’s an affordable insurance policy for anyone who relies on their action camera for work or play. In this comprehensive review, I’ll walk you through everything you need to know about the DJI Osmo Action 4 Glass Lens Cover—from its build quality and real-world performance to customer feedback and whether it’s worth your money.
What is the DJI Osmo Action 4?
The DJI Osmo Action 4 is one of the most popular action cameras on the market, known for its exceptional image quality, rugged design, and advanced stabilization features. But even the toughest cameras need protection—especially the lens, which is constantly exposed to dust, dirt, impacts, and the elements. That’s where the DJI Osmo Action 4 Glass Lens Cover comes in. This isn’t just a spare part; it’s an essential accessory for anyone who pushes their camera to the limit.
This lens cover is a direct replacement for the original glass that comes pre-installed on the DJI Osmo Action 4. It’s crafted from high-strength optical glass and features an AF (anti-fingerprint) coating that resists smudges, oils, and everyday wear. The cover is precision-machined to match the exact dimensions of the original, ensuring a perfect fit without any gaps or misalignment. With a weight of just 7.2 grams and dimensions of 32.25×32.35×4.48 mm (L×W×H), it’s lightweight yet durable—designed to withstand the rigors of extreme sports, travel, and daily use.
The target audience for this product is broad but specific: action camera enthusiasts, outdoor adventurers, content creators, and professionals who rely on their DJI Osmo Action 4 for high-stakes filming. Whether you’re mountain biking, skiing, surfing, or racing drones, the risk of lens damage is real. Having a spare lens cover on hand means you can quickly swap out a cracked or scratched lens and get back to filming without missing a beat. It’s also ideal for users who’ve already experienced lens damage and want to ensure they’re using a genuine, high-quality replacement rather than a third-party alternative that could compromise image quality.
Key Features of DJI Osmo Action 4
High-Strength Optical Glass
One of the standout features of the DJI Osmo Action 4 Glass Lens Cover is its use of high-strength optical glass. This isn’t your average window pane glass—it’s engineered to resist impacts, scratches, and daily wear while maintaining optical clarity. In my testing, I found that the glass feels noticeably thicker and more robust than third-party alternatives I’ve tried in the past. When I dropped my camera (accidentally, of course) onto a rocky surface, the lens cover held up without a scratch, while the camera body took the brunt of the impact. This level of durability is crucial for action cameras, which are often subjected to harsh environments.
The optical quality is equally impressive. Unlike some aftermarket lens protectors that can introduce haze or reduce sharpness, this cover preserves the full clarity of the original lens. I compared footage shot with the original lens and the replacement cover side by side, and there was no noticeable difference in color accuracy, contrast, or detail. This is a big deal for content creators who rely on crisp, professional-looking video. The high-strength glass also resists cracking under pressure, which is especially important if you’re using your camera in cold conditions where materials can become more brittle.
AF (Anti-Fingerprint) Coating
Another key feature is the AF coating, which stands for anti-fingerprint. This hydrophobic and oleophobic layer repels oils, water, and smudges, making the lens easier to clean and less prone to buildup. In real-world use, I noticed that fingerprints and smudges wiped off easily with a microfiber cloth, and the lens stayed clearer longer during extended filming sessions. This is particularly useful when you’re filming in humid or sweaty conditions—like during a long hike or intense workout—where moisture and oils can quickly accumulate on the lens.
The AF coating also helps prevent water spots and dust adhesion, which can degrade image quality over time. I tested this by filming in light rain and near a beach, where salt spray and sand are common. The lens cover remained clear and functional, with no significant buildup or distortion. This coating is a subtle but valuable addition that enhances both usability and longevity. It’s the kind of detail that separates a premium product from a budget alternative.
Precision Fit and Seamless Installation
One of the biggest frustrations with third-party lens covers is poor fitment—either they’re too tight, too loose, or don’t align properly with the lens housing. The DJI Osmo Action 4 Glass Lens Cover eliminates these issues with a precision-engineered design that matches the original exactly. The dimensions—32.25×32.35×4.48 mm—are spot-on, and the cover snaps into place with a satisfying click. I installed it in under 30 seconds without any tools or adhesive, and it felt secure from the moment it was in.
The seamless fit also ensures that there’s no gap between the cover and the camera body, which helps prevent dust and moisture from seeping in. This is critical for maintaining the camera’s internal components and ensuring long-term reliability. I’ve used other lens covers in the past that left tiny gaps, and over time, dust accumulated around the edges, requiring frequent cleaning. With this DJI cover, I haven’t had that issue at all. It’s a small detail, but it makes a big difference in daily use.
Scratch and Stain Resistance
Durability is a major selling point for the DJI Osmo Action 4 Glass Lens Cover, and its scratch and stain resistance is a big part of that. The high-strength glass is treated to resist everyday abrasions, from sand and gravel to keys and other hard objects. I tested this by intentionally rubbing the cover against rough surfaces (in a controlled manner, of course), and it held up remarkably well. There were no visible scratches or scuffs, even after repeated exposure.
Stain resistance is equally important, especially if you’re filming in environments where the lens might come into contact with dirt, mud, or other contaminants. The AF coating plays a role here too, but the glass itself is engineered to resist discoloration and etching. I filmed in a dusty desert environment for several hours, and while the lens did pick up some fine particles, they wiped off easily without leaving stains or residue. This level of resilience ensures that your lens stays clear and functional, even in the toughest conditions.
Lightweight and Compact Design
At just 7.2 grams, the DJI Osmo Action 4 Glass Lens Cover is incredibly lightweight—so light, in fact, that you barely notice it’s there. This is a major advantage for users who prioritize portability and minimal bulk. Whether you’re mounting your camera on a helmet, handlebar, or drone, every gram counts, and this cover adds virtually no weight to your setup. I’ve used heavier third-party protectors in the past, and the difference is noticeable, especially during long filming sessions or high-speed activities.
The compact dimensions also make it easy to store and transport. I keep a spare in my camera bag, and it takes up almost no space. It’s small enough to fit in a pocket, a small case, or even the original packaging. This makes it ideal for travelers, adventurers, and professionals who need to carry backup gear without adding bulk. Despite its small size, it doesn’t compromise on durability or performance—a rare combination in the world of camera accessories.
Official DJI Compatibility
One of the biggest advantages of the DJI Osmo Action 4 Glass Lens Cover is that it’s an official DJI product, designed specifically for the Osmo Action 4. This ensures full compatibility and eliminates the guesswork that comes with third-party alternatives. I’ve tried generic lens covers in the past, and while some work okay, others cause issues like autofocus problems, reduced image quality, or even damage to the camera housing. With this official cover, I’ve had zero compatibility issues.
Being an official product also means it’s backed by DJI’s quality assurance and customer support. If something goes wrong—though it’s unlikely—you can reach out to DJI directly for assistance. This level of support is invaluable, especially for professionals who rely on their gear for income-generating work. It’s also a sign of DJI’s commitment to their ecosystem, ensuring that users can maintain and repair their devices with genuine parts.
Affordable Replacement Solution
At $29.00, the DJI Osmo Action 4 Glass Lens Cover is an incredibly affordable way to protect your investment. Replacing a damaged lens on the Osmo Action 4 can cost significantly more if done through official repair channels, and third-party replacements often come with hidden costs in terms of quality and reliability. This cover offers a cost-effective solution that doesn’t compromise on performance.
Think of it as insurance for your camera. For less than the cost of a coffee and a pastry, you’re getting a high-quality, durable lens cover that can save you hundreds in potential repair bills. I keep two on hand—one as a spare and one as a backup—because the peace of mind is worth every penny. It’s a small price to pay for the confidence that your camera will keep rolling, no matter what you throw at it.
How Does DJI Osmo Action 4 Perform?
Real-World Testing: Mountain Biking
I took the DJI Osmo Action 4 with the new lens cover on a challenging mountain biking trail to test its performance under real-world conditions. The trail was rocky, dusty, and exposed to direct sunlight—perfect for putting the lens cover through its paces. I mounted the camera on my helmet and filmed for over two hours, navigating steep descents, sharp turns, and occasional jumps.
The results were impressive. The lens cover held up perfectly, with no scratches, cracks, or signs of wear. Even after hitting a few bumps that sent the camera bouncing, the glass remained intact. The AF coating did its job, repelling dust and sweat, and I only needed to wipe the lens once during the entire ride. The footage was crystal clear, with no distortion or haze—exactly what I’d expect from the original lens. This test confirmed that the cover is more than capable of handling the demands of extreme sports.
Performance in FPV Drone Racing
One of the most demanding uses for an action camera is FPV drone racing, where the camera is subjected to high speeds, sharp maneuvers, and the constant risk of crashes. I mounted the DJI Osmo Action 4 on a racing drone and flew several aggressive laps around a technical course. The drone took a few hard hits, including one that sent it skidding across concrete.
After the flight, I inspected the lens cover. It had a few minor scuffs from debris, but no cracks or deep scratches. The camera continued to function normally, and the footage was sharp and stable. This performance is a testament to the cover’s durability and impact resistance. For drone racers, having a reliable lens cover is essential—because crashes are inevitable, but missing the shot doesn’t have to be.
Everyday Use and Travel
I also tested the lens cover during everyday use—filming walks, city tours, and casual outings. The cover performed flawlessly, resisting fingerprints, smudges, and light scratches from daily handling. I accidentally dropped the camera once on a tiled floor, and while the body took a hit, the lens cover remained unscathed. The AF coating made cleaning a breeze, and the lens stayed clear throughout the day.
For travelers, this level of reliability is a game-changer. You don’t want to worry about your camera’s lens getting damaged while you’re exploring a new city or hiking a remote trail. The DJI Osmo Action 4 Glass Lens Cover gives you the confidence to film freely, knowing your gear is protected.
Comparison to Expectations
Before testing, I had high expectations for this lens cover, given DJI’s reputation for quality. I’m happy to say it exceeded them. The build quality, optical clarity, and ease of installation were all top-notch. It performed exactly as advertised, and in some cases—like impact resistance—it outperformed my expectations. This is a product that delivers on its promises, and that’s rare in the world of camera accessories.
