Backscatter M52 81° Wide Angle Air Lens

The Backscatter M52 Wide Angle Air Lens is a wet-mount wide angle conversion lens designed to work best with Olympus TG series camera housings. The lens cancels out refraction and restores the camera’s topside field of view underwater while also enhancing the image clarity, sharpness, and contrast.
 
Olympus TG Lens Comparison

With an 81° angle of coverage, sharp corners, no vignetting at 24mm, and an easy to use 52mm threaded mount, this lens is perfect for both veteran and new wide angle underwater photographers. It’s the most versatile lens for shooting both macro and wide angle on the same dive with the Olympus TG-5 or TG-6 because you never have to remove the lens.
