Manual Focus Adjustment Upgrade for Logitech C270 Webcam This upgrade is designed to be compact and minimalistic, making it easy to install without requiring extra screws. Other designs found online often necessitate additional screws and are bulkier in size. To enable manual focus adjustment on the webcam, you'll need to disassemble the camera and remove the glue holding the focus adjustment in place. A helpful video outlining this process is available here: https://www.youtube.com/watch?v=v-gYgBeiOVI Once you've completed the disassembly, you can proceed with installing the cover and adjustment ring. Start by attaching the front plate using the existing screws, then snap the focus ring into position. The "rails" will require a bit of glue to secure them properly. To maintain a minimalist design, I used this approach as it seemed most effective.
