It’s a problem as old as photography: your camera is only as good as your lens. As cameras shrink, so do lenses, and so do the options for upgrading to a better lens. And forget about switching to a different focal length or aperture — it’s often just not an option. Unless you make it an option by adding a CS lens mount to a high-end webcam.

We’ll stipulate that at 4k resolution and packed with all sorts of goodies, the Logitech Brio Pro is a heck of a nice camera. And the lens isn’t bad either, as you’d hope for a camera with almost 9 megapixels at its disposal. But with an optical field of view optimized for video conferencing, it’s hard to use this premium camera for much else. [Saulius] fixed that by taking the camera apart and adding a new case with a built-in C- and CS-mount, resulting in literally thousands of lens choices. [Saulius]’ post has valuable teardown information, which includes exposing the CCD sensor completely. The new case is sold as a kit, but it looks like a 3D-printed case would be pretty easy to whip up.

[Salius] sure seems to love those optical hacks, whether they be a budget microscope camera, high-resolution LIDAR, or capturing license plates at great distances.
