From CNet Asia comes a video on the lens cap you can’t misplace. That remains to be seen, but it’s clever.
The Flip Cap’s name speaks for itself and is a lens cap that flips up and out of the way when you want to take a picture. You attach the contraption to your camera lens via the filter thread and press a button for the spring-loaded cap to flip open.
I could buy a new camera with all the lens caps I’ve misplaced through the years.
I’ve used clunkier accessories.
