Capkeeper
Never lose your lens cap again with this Capkeeper from Sensei. One end of the CK-L has an elastic band which attaches securely around your lens barrel, while the other end fastens to your lens cap via an adhesive-backed disc. It can be used to secure your lens cap to your DSLR, video, or compact camera. The cap remains tethered while shooting and is easily retrieved when finished.
