The Swarovski Snap Shot Adapter forms the link between a Swarovski SLC or 42mm EL series binocular and a digital camera resulting in clearly focused long range images. Using this adapter, you can easily turn your binocular into a digiscoping lens. All that is necessary is a digital camera with a maximum 4x optical zoom lens. It helps if your camera has manual focusing or an infinity mode, and manual or aperture-priority exposure as well (you should manually focus your camera to infinity, and always use the largest aperture).Affixing the Snap Shot to your binocular is easy; it simply fits by friction to the camera, and then camera and Snap Shot adapter together take the place of your binocular's eyecup (which must be removed)Perfect for nature observation, for outdoor activities and as a traveling companionAffixes to camera via simple push-fit friction Swarovski EL Range SSA S2 44077
