BlurFix

BlurFix™ Adapter

CNC machined aluminum (6061-T6)
Tested to a depth of 130ft -- advanced open water (AOW) max dive depth
Accepts all 55 mm camera filters including clear, UV, FLD, red, and polarizing
Clear filter included
Has superior optical qualities of glass filters compared to plastic lenses
Can be used above water with no vignetting in all modes when filter and o-ring are removed (you can use one GoPro housing both above and below water!!)
With the included low-profile UV filter installed for underwater use, there is limited vignetting in r4 (960p mode) with no vignetting in r1 (480p mode), r2 & r3 (720p modes), and r5 (1080p mode)*
Stepped chamfer on inside of lens
Type III Anodized (MIL-A-8625) that improves optical qualities as well as provides a robust finish to the aluminum
Ceramic desiccant ball groove so that fogging is never an issue (reusable desiccant balls included)
Should your filter shatter while you are diving because you dive too deep or bump the filter against a rock, your GoPro camera will stay dry because the integrity of the OEM housing and lens stays intact.

* Some Hero2 cameras have experienced minimal vignetting in two corners in WIDE mode. This typically only applies to above water applications as the mechanical vignetting usually disappears underwater.

Includes everything seen in the picture. GoPro camera, case, and mount not included.
