GoPro Anamorphic 3mm
Auto-detection by the HERO13 Black enables in-camera de-squeezing of the 3mm f/2.5 lens, delivering 21:9 footage with reduced distortion and cinematic horizontal flares. The 77-gram mod attaches tool-free and maintains waterproof durability with a scratch-resistant, hydrophobic coating, while HyperSmooth stabilization support steadies handheld shots. This lens is best for action vloggers and street filmmakers who want ready-to-edit widescreen footage straight from the camera.
