The LockCircle billet aluminum camera body cap replaces the plastic body cap that comes with your DSLR. The LockCircle folks say that it locks in place with a Swiss watch feel.
These camera body caps are available in silver, titanium or black finishes and cost $99 each. They are available in Canon EF-mount and Nikon F-mount flavors.
Frankly, I don’t see the utility of this device; however, I’m open to your thoughts on why a camera body cap should cost $99.
