Lens cap JJC L-r1 — compatible with Canon camera bodies and lenses

JJC L-r1 is a replacement rear lens cap compatible with Canon camera bodies and a range of Canon-mount lenses. Designed to protect the lens mount and rear glass element from dust, moisture and scratches, this lightweight cap helps maintain optical performance and keeps equipment clean during storage or transportation. It fits securely onto lenses and camera bodies that accept Canon-compatible rear caps and is intended as a practical accessory for photographers who swap lenses or store gear between shoots.

Advantages

The cap provides reliable protection for the rear element and the lens mount surface while remaining compact and easy to carry. Its simple bayonet-style fit allows quick attachment and removal without tools, and the durable construction resists minor impacts and abrasion. Because it is lightweight, it does not add noticeable bulk when stored in a camera bag or kit pouch.

Suitable for

• Protecting Canon-mount lenses during storage
• Covering lens mount when transporting loose lenses
• Protecting the rear element during lens changes in the field
• Keeping spare lenses dust- and moisture-free in a camera bag

How to use

Align the cap with the lens rear or camera mount so that the locating marks match, then press gently and rotate until it locks into place. To remove, press the release tabs (if present) and rotate the cap in the opposite direction until it releases. Use the cap whenever a lens is detached from the camera body or when storing lenses to avoid dust and moisture settling on the mount or rear element.

Usage recommendations

Store the JJC L-r1 cap clean and dry; wipe it with a soft cloth if it becomes dusty. Avoid exposing the cap to extreme heat or solvents. Before attaching the cap, check the lens mount and rear element for large debris that could scratch the glass. Replace or complement with a front lens cap for full protection of the lens when not in use.
