Swarovski Optik's TLS APO 23mm Digiscoping Lens makes it easy to use a Swarovski spotting scope as a telephoto lens for a Micro Four Thirds camera, achieving sharp images and video of distant details. Its 23mm apochromatic lens eliminates spherical and chromatic aberrations, so images have true color rendition with zero distortion across the entire frame. When the TLS APO, a T2 adapter, and camera body are mounted to the spotting scope eyepiece, users are treated to a truly stunning digiscoping experience. The TLS APO's lens 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. A camera and T2 camera adapter are required to complete the Swarovski digiscoping system, and are not included.
