Swarovski Demo Products Swarovski demo products have been slightly used for display or demonstrations by Swarovski during outdoor industry events. They may exhibit minor cosmetic imperfections that will vary from demo product to product. Swarovski demo products and their included accessories are guaranteed by Swarovski to operate to the standards for a new product. In rare cases, one or more accessories may be missing. All Swarovski demo products are covered by the Swarovski Limited Lifetime Warranty (View Warranty). The TLS APO Digiscoping Adapter was made for ATS/STS HD, ATM/STM Spotting Scopes. Swarovski uses a proprietary adapter to connect a DSLR or mirrorless camera body to the viewing module of ATS/STS HD, ATM/STM series spotting scopes. A T2 camera adapter is also a requirement to complete the Swarovski digiscoping system. When the TLS APO, T2 adapter, and camera body are mounted to the spotting scope eyepiece, users are treated to a truly stunning digiscoping experience. The TLS APO has a 30mm apochromatic pancake lens that perfectly aligns the camera sensor with the focal plane of the transmitted image. Regardless of the camera used, you will capture contrast-rich and sharp video and still images using the premium optics of your Swarovski spotting scope.
