Canon E73 Lens Cap

I was worried the cap might be too tight on the fisheye, but it slides on easily and locks in place perfectly. It fits my EF 8-15mm lens like a glove, and I feel a lot better leaving it in my bag now knowing the front element is protected from dust.

The clip mechanism is snug and secure on my 8-15mm fisheye, so I'm not worried about it popping off in my bag. It's nice to finally have proper protection for that bulbous front element.

Finally, a cap that actually fits this lens snugly without any wobble — it clicks on perfectly. The rigid plastic feels sturdy enough to protect the front element from bumps in my bag.
