Lens Extender Cap RF by Canon — Compatible with Extender RF1.4x and RF2x, Black

Canon Lens Extender Cap RF is a protective cap designed specifically for Canon RF-mount extenders, including Extender RF1.4x and Extender RF2x. Finished in black, the cap shields extender mounts and optical contacts from dust, scratches and accidental impact during storage and transport. It is intended for use with digital camera systems that employ RF-mount extenders and provides a simple protective solution when the extender is not attached to a camera or lens.

Advantages

The cap offers form-fitting protection that helps maintain the integrity of the extender’s mechanical and electronic contacts. Its durable construction reduces exposure to dust and contaminants, while the snug fit minimizes the risk of scuffs or minor impacts during handling. The plain black finish integrates discreetly with camera gear and is lightweight for easy packing.

Suitable for

• Photographers who store RF1.4x or RF2x extenders between uses
• Travel and field use to protect extender mounts during transport
• Studio equipment storage where dust prevention is required

Key specifications

How to use

To use the cap, align it with the extender’s mount and press gently until it seats securely over the extender’s rear or front mount as applicable. Ensure the cap fully engages so that optical and electronic contacts are covered. Remove the cap by pulling it straight off without twisting to avoid contacting the extender’s surfaces. Store the extender with the cap attached in a padded bag or case to reduce movement and further protect against impacts.

Usage recommendations

Keep the cap clean and free of grit; wipe periodically with a soft, dry cloth. Avoid exposing the cap to extreme heat or prolonged sunlight to preserve its fit and material properties. When storing for extended periods, inspect contacts and clean the extender and cap before reattaching.
