The integrated folding handle design of the Don Zeck Lens Cap allows you to quickly install or remove it when traditional snap-on lens caps are too awkward and slow to keep up with sports or action shooting. Regular lens caps can be challenging to use with deep lens hoods, but these rigid plastic protective caps can be used with the hood in the active or stored position, or even without the hood at all. When you're ready to shoot just pull the cap off by its handle and you're ready to go.

The lens cap is held in place using six O-rings, which provide a tight, perfect fit without touching the lens surface or damaging your lens.
