The Canon 8-15 Lens Cap is a specialized protective accessory designed to shield the protruding front glass of the EF 8-15mm f/4L Fisheye USM lens, which cannot accommodate standard screw-in filters.

No, this cap is specifically designed for the unique dimensions of the EF 8-15mm f/4L Fisheye USM. It will not fit standard threaded lenses like the 24-70mm or 70-200mm.
The cap is made of moisture-resistant plastic and protects against splashes and dust, but it does not create a waterproof seal for the lens.
It uses a side-pinch mechanism. You squeeze the two side buttons to retract the internal clips, slide it over the lens front, and release to lock it into the dedicated groove.
