Included with every GoPro HD HERO2 camera from FreediveStore.com is your choice of an additional free item; a flat Makrolon lens that fixes the GoPro underwater focus problem, a pistol grip handle, or a 16GB SD card. The flat lens fixes the underwater focus/blurry problem caused by the original Gopro curved lens. Now you can take crisp high definition undewater video without resorting to do it yourself housing lens fixes, which were previously the only way to have the GoPro to take good underwater video.

The flat lens is a drop in replacement for the original GoPro housing curved lens. It has a depth rating of up to 180ft, the same as the Gopro housing. The lens is made of Makrolon, an amorphous thermoplastic material noted for its outstanding impact strength, superior dimensional stability, glass-like transparency, excellent thermal resistance, and low-temperature toughness. See complete description of the lens including important installation instructions in the lens product pages.

* It's a must to test any housing at depth before using it with the camera. This holds true for the GoPro housing whether with the original lens or the flat lens. FreediveStore.com will not assume responsibility for water damage to cameras under any circumstances.

Spearfishing video shot in high definition with the Gopro Hero HD and a flat lens.

Video demonstrating effect of the flat underwater lens at the 5 different available settings available in the GoPro HD HERO camera; R1, R2, R3, R4, and R5. R5 is the most suitable high definition setting for filming underwater and has no vignette effect. The equivalent setting to R5 in the HERO2 camera is 1080p @ 127 FOV 30 FPS.

We often get asked if it's difficult to install the flat lens in the Gopro housing. What better way to demonstrate how easy it is than by doing it outdoors, on a breezy day, with a small uneven work surface, and two lenses at once. Adding the risk factor of dropping something in the water for extra tension Total install time less than 5 minutes. Video was shot with a GoPro HD HERO camera in R5 setting, mounted on a head strap.
