Compact cameras feature lenses that automatically “cap” themselves when retracted and not in use. Interchangeable lenses, on the other hand, usually don’t. The X-Cap changes that. It’s a Taiwan-designed lens cap that snaps onto the front of certain lenses that feature a retracting front element (the Micro Four Thirds system has lenses like this). When the front element retracts, the cap automatically closes — great for people who hate dealing with lens caps.
Here’s a video showing the cap in action:
