The Don Zeck Lens Cap is unique in the world of lens accessories. It is the first lens cap designed with an ergonomic handle to help you both place and remove the cap. The advantage of this is obvious.
This cap can be used with a long hood in place. During such times, it can be difficult to use a traditional "snap on" lens cap. Using this particular, cleverly designed cap means that you can set up your long lens (that has a deep hood) and leave the cap on. Yet, when it comes time to actually shoot, all you need to do is grab the neat little handle, pull the cap off and you're ready to shoot. No more having to remove the hood or awkwardly reach inside the hood to try to unhook the cap.
The cap is held in place using six "O" rings that create a tight, perfect fit. In addition, the unique handle will compress to an ultra thin 3/16" when you store your lens in its case. The "O" rings never touch the lens surface and will not damage your lens. This cap is a thick design and will guard your optics from the damage that we all fear with long (or short) expensive lenses.
Cap can be mounted on the lens while the hood is in the shooting position or in the stored position
Handle allows a firm grip on the cap so that it can be easily installed
Can be used with or without the factory lens hood
An interesting alternative to the traditional "sock" hoods that come with longer lenses
