This Lens Cap Holder from Capbuckle holds 37mm, 40.5mm, 43mm, and 46mm lens caps, and provides you with a secure and out-of-the-way system to hold your lens cap. The design copies the front of your lens and is sized to hold the cap. The Capbuckle threads to your shoulder strap eliminating the need for any dangling cap holder that might swing in front of your lens. Just squeeze the locking mechanism on your lens cap and put it in the Capbuckle where it remains locked on the camera's strap.
The Capbuckle holds different sizes of lens caps on each side of the holder. Multiple Capbuckles can be attached to your camera strap to accommodate various size lens caps. This is a lightweight, durable way to make sure your lens cap is safe and readily accessible.
