The White S Clip Lens Cap Clip from hufa is designed to prevent the loss of your lens cap when it has been removed for shooting. It's a follow-up to their standard Lens Cap Clip and is designed for narrower sling style straps and 1" wide camera and bag straps.
The S Clip is oriented vertically rather than horizontally which stabilizes it once clipped on the more narrow straps. The S clip attaches to the camera strap in the same manner as the original but provides an under then over design to keep the clip (and your lens cap) securely in place.
Of course, the S Clip does not have to attach to a camera strap, you can clip to your backpack, camera bag or belt and you'll always know exactly where your lens cap is. No more fishing through five pockets to find your lens cap when it's time to change lenses and no more lost lens caps.
The S clip holds any kind of flat lens cap and if you have more than one cap, the S clip can be stacked along your strap for multiple lens caps. S Clips are available in black, red and white and can be mixed and matched for style or to help organize your lens caps.
