While I've been lucky never to have actually misplaced a lens cap for my digital SLR, there have been times when I've been lost for somewhere to put it between shots (no suggestions please). Chicago's Mark Stevenson has designed a simple solution to allow photographers to secure the wandering lens cap to a camera strap or camera bag.

Stevenson says that the idea for the holder came to him after he lost his camera's lens cap while at the hospital to witness the birth of his daughter. Four prototypes later and the mechanical engineer's patent-pending plastic lens cap holder is ready for commercial production. As I write, his Kickstarter project has reached its funding target and production is scheduled to start within the next couple of weeks, with shipping promised a few week after.

The lens cap's clamping mechanism is used to grip or release the circular recess between the buckle holes of the holder. A camera strap is slotted through the buckles and then the holder can be positioned where it's convenient for you to pop your cap in it when it's not busy protecting your precious lens. Each lens cap holder is designed to hold three or four different-sized lens caps (two on one side and one or two on the other), although (obviously) only one cap can be secured in the holder at any one time.

The holder will initially support 40.5, 46, 49, 52, 55, 58, 62, 72, 76 and 77 mm lens cap sizes which will make the solution compatible with lenses from Nikon, Pentax, Fujifilm, Canon, Olympus and Sony, as well as lenses for Micro Four Thirds cameras, and vintage and Pro Series models.

Pricing will initially be set at US$19.95, availability information will be appear on the product page shortly.
