Abstract
A permanently-affixed lens cap is presented here. This is a lens cap which one does not have to separate from the camera, to use the camera. Unlike the existing lens caps which clip on the front, and are then removed, these caps remain on the front of the lens practically at all the times. Thus, they do not get lost, and the camera/lens is much safer because of it. Some of the features are: Crystal Clear: a Lens cover which looks like a filter, in that it screws into the filter thread at the end of the lens. This protects the expensive lens from impact and scratches. As an option, the user never has to remove it. Nano-Technology coating: Two separate layers of fine silica particles prevent scratches, and fluorine-containing resins in each layer repel ink marks. This has been used for DVD protection in the industry. Bullet-Proof: Layers of glass and (clear) plastic sandwiched to give great optical clarity, but an incredibly impact resistant front. Non-clear lens, which is permanently attached. The lens cap has a mechanism to flip out of the way. Press a button and the lens cap expands to become a shade, and exposes the front of the lens. Many other variations and extensions are also discussed in the specification and figures.
