Magnetic Lens Cap K&F 67mm — M-cap magnetic lens cover, model SB8355

The Magnetic Lens Cap K&F 67mm (model SB8355) is a magnetic M-cap designed to protect camera lenses with a 67 mm filter thread. The cover secures to the front of compatible lenses by magnetic attraction, enabling fast attachment and removal while providing basic protection against dust, light and superficial scratches during storage or transport. The design accommodates common 67 mm filters and adapters without the need for additional clips or threads.

Advantages

The magnetic mount allows rapid on/off operation, saving time when changing lenses or moving between shooting conditions. Its low-profile construction maintains compatibility with screw-on filters and step-up/step-down rings that use a 67 mm thread. The cap provides a protective barrier for the front element while remaining easy to handle, and its simple mechanical design reduces the risk of wear compared with elastic or clip-based covers.

Suitable for

• Photographers who require quick lens protection during travel or storage
• Users who frequently attach or remove front filters on lenses with a 67 mm thread
• Owners of camera kits with adapters or step rings that preserve a 67 mm front thread

Key specifications

• Thread compatibility: 67 mm filter thread
• Attachment type: magnetic mounting to metal ring or magnetic adapter
• Purpose: front element protection from dust, light and light abrasion
• Profile: low-profile design suitable for use with front-mounted filters and rings
• Material: durable lightweight construction for everyday use

How to use

Align the magnetic lens cap with the front of the lens so the threads or metal mating surface sit flush, then let the magnets draw the cap into place until it is secure. To remove, grip the outer edge and pull straight away from the lens to disengage the magnetic connection. For lenses fitted with non-metallic rings or covers, ensure the mating surface is compatible or use an appropriate magnetic adapter to enable reliable attachment.

Usage recommendations

Store the cap clean and dry when not in use; wipe both the cap and the lens front with a soft, lint-free cloth if dust or grit is present before attaching to avoid scratching. Use the magnetic cap as a quick protective measure during transport and short-term storage, and continue to use screw-on rear or lens-specific caps when performing longer-term storage or exposure to harsher environments.
