Computar 1/2″ 9mm f2.0 High Res M12. Great for low light, this lens features a relative aperture of f2.0 as opposed to the f3.0 commonly found in other M12 lenses. The stock GoPro lens has an aperture of f2.8. This lens comes without an IR-Cut filter built in, so it’s perfect for night vision use! If you have permanently installed the IR cut filter in your Ribcage this lens will shoot great footage in daylight as well. Those who have configured their IR-cut as removable will have to remove the filter to use this lens. 35mm equivalent focal length ~50mm. Note: this lens requires an M12 to CS adapter in order to focus with the Ribcage. We recommend purchasing one if you don’t already have one. You can always get one adapter for each or your M12 lenses that require one so you can do quick lens changes on the fly!

We recommend connecting your camera to a monitor when focusing the lens in order to ensure a perfectly sharp image. Screw the lens in while pointing the camera at a detailed area 12 – 15 feet away until the image becomes clear. Make sure you achieve crisp focus across the entire image from left to right and then lock it in with the Ribcage set screw, or if using the M12 to CS adapter use the provided locking nut when the correct focus position is found. Tighten only until snug as over-tightening can cause damage. If you don’t have access to a monitor or HDMI cable you can check focus with the mobile app or LCD bacpac. An M12 locking ring is also included with the lens.
