The cap easily slips onto the front of your 58mm lens. An included adapter allows you to use the cap with a bayonet mount.

The older version of the 300mm f/2.8L IS has a front filter thread, and can take any 77mm lens cap, such as this one by Sensei: http://bhpho.to/1dXg1ua. It is not advised to use the E-145C with the lens hood.
