Nikon lens cap LC-77B

The Nikon LC-77B 77mm Lens Cap is a snap-on protective cover designed for 77mm filter-thread NIKKOR lenses, helping protect the front optical element from dust, scratches, and impact.

The Nikon LC-77B 77mm Lens Cap is an original Nikon front lens cap designed for NIKKOR lenses with a 77mm filter thread, including high-performance zoom and prime lenses such as the 70–200mm f/2.8 S series.

It attaches securely to the front of the lens using a spring-loaded snap-on mechanism, allowing quick installation and removal while providing reliable protection when the lens is not in use. The cap helps prevent dust, dirt, moisture, and accidental scratches from reaching the front lens element—preserving optical clarity and extending lens life.

This type of cap is especially important for professional lenses, where front element damage or contamination can directly affect image quality and require costly maintenance.
