DJI Osmo Action 4 Glass Lens Cover, scratch- and smudge-resistant glass

Made from glass and measuring 32L x 32W millimetres, the DJI Osmo Action 4 Glass Lens Cover is a protective cover for the camera lens. Its AF coating is described as stain- and scratch-resistant, making it relevant if you want an extra layer between the lens and marks from everyday handling.

The package includes one lens protective glass, weighing 7.2 g. It is listed as compatible with the Osmo Action 4, it is not a general-purpose cover for other cameras or mobile phones.

Key takeaways

This is a small, single-purpose accessory rather than a camera upgrade: it adds glass protection to the Osmo Action 4 lens. The scratch- and smudge-resistant properties are useful considerations for a camera that is handled, packed away or carried between filming locations. The matte finish is also specified, though the listing does not explain how it affects the image or handling.

It’s a good fit if you own an Osmo Action 4 and want protective glass for its lens. Not the best choice if you need a cover for another camera, or if your priority is water protection: the stated water-resistance level is “Not Water Resistant”.

Fit and sizing

Compatibility is specifically given as Osmo Action 4, so the main buying check is whether that is the camera you have. The stated dimensions are 32L x 32W millimetres, and the product weighs 7.2 g. Those details give a sense of its compact format, but the listing does not provide fitting instructions or additional measurements such as thickness. Avoid treating it as a screen protector: it is described as a lens cover.

If you are choosing between this and a more basic approach, such as carrying the camera without separate lens protection, this accessory is the dedicated option for adding glass over the lens. It does not replace a broader camera case, and its stated resistance to marks should not be confused with protection from water.

Usage tips

Use the product for the Osmo Action 4 lens, keeping its intended role in mind: extra protection against scratches and smudges. For example, it may suit someone packing the camera with other kit and wanting a separate glass layer over the lens. The included quantity is one, so the box contents are straightforward. The available details do not explain how the cover attaches or how to remove it, follow the product’s fitting guidance rather than assuming a particular installation method.

The AF coating and glass construction are the key distinguishing details here. They make this more specific than a generic camera accessory, but they do not establish that it will prevent every mark or withstand impact. The listed water-resistance level is also not water resistant, so this cover should not be chosen as a way to make the camera suitable for wet conditions.

Final verdict

Choose the DJI Osmo Action 4 Glass Lens Cover if you want a dedicated glass layer for that camera’s lens and value the stated scratch- and smudge-resistant coating. Its clearly stated compatibility, compact dimensions and 7.2 g weight help identify what is being bought, while the one-piece pack keeps the purpose narrow. If you need water protection, a cover for a different device or a complete camera case, the details here do not support treating this as a substitute.
