OM SYSTEM LC-77C Lens Cap, 77mm 

Pinch design lens cap suitable for all lenses with a 77mm front filter thread.

A front lens cap is one of the simplest and most effective ways to protect your camera lens. While it might seem like a small accessory, it helps prevent damage that can be expensive to repair.  

Use the lens cap in conjunction with a clear / UV filter for added protection.

• Helps protect the front element from scratches
• Keeps dust and dirt off the lens. A cleaner front element means less time spent cleaning and less chance of rubbing abrasive particles across the glass
• Prevents fingerprints and smudges. Oils from your fingers can reduce contrast and increase flare, especially when shooting into bright light.
• Provides some protection against bumps. If your camera knocks into a doorframe, table, or another object, the cap often takes the impact instead of the lens itself
