Lens Cap for Canon RF 10-20mm f/4 L IS STM lens.

High Quality and Excellent Selling Service, Fully Satisfied With My Needs.

Excellent product - I was impressed with the quality, fine detail and ease of fitting this to the lens. I also found that one lens cover manufacturer (Chasing Birds) was well attuned to your products and promptly provided the appropriate cover (perfect fit) for your tailor-made lens hood. Thank you.

A much better solution than the stock Canon lens cap

This fits flush on the end of the lens so it stays on when in a camera bag or a pouch. The stock Canon cap is wider at the end so it is always getting knocked off when in a bag or pouch, risking that something could damage the end convex element.
As always, Zemlin is solving problems that the manufacturers ignore.
