PUT CANON LENSES ON YOUR GOPRO!!! Remove the GoPro lens and swap it out with a cheap alternative, then take it apart to get your hands on the IR-Cut filter or buy one that fits your Canon lens. Use a spring from a ballpoint pen, cut in half, as the lock spring. Lens Instruction For IR-Cut The IR-Cut has nothing to do with focus; it simply cuts out IR light. You can shoot without this step, but the image will take on a pink hue in sunlight. Cheap Way With Less Cost Take out the original GoPro lens and replace it with a cheap alternative or disassemble the GoPro lens to get access to the IR-Cut Filter (the glass with a red/blue reflection). Leave just the IR-Cut filter and put the lens back together properly or upside down; pictures show the lens installed backwards. Easy Way With More Cost Alternatively, you can buy an IR-Cut filter that fits your Canon lens. I opted to modify my GoPro lens so it would work with all of my Canon lenses.
