With the Insta360 X4 Air Standard Lens Guards, you protect the lenses of your Insta360 X4 Air action camera from scratches and bumps. The special coating on the glass lens guards lets you capture your favorite action moments in clear 360-degree footage. The camera automatically switches to Lens Guard Mode when you attach the lens guards. The camera removes the edge of the lens guards from the image, so they don't appear in your footage.
