The Defender was designed to protect the front element of your lens from dirt, moisture, and minor collisions. Compatible with most pro-level lenses on the market, the Defender’s dual-density construction combines a hard, rigid lens plate, and an easy-to-install flexible polymer exterior; ensuring a snug and secure fit compared to standard plastic lens caps and flimsy universal lens covers.

To choose the correct fit, simply measure your lens' outer barrel diameter in millimeters and select the Defender cover within that range. For example, if you have an 84mm outer lens barrel, the "77mm-82mm" option would be for you!
