Swarovski TLS APO Telephoto Adapter

Convert your Swarovski ATX/STX spotting scope into a super telephoto lens with the TLS APO telephoto adapter.

The average telephoto lens is about 200mm. The TSL APO converts the ATX/STX 65mm or 85mm spotting scopes into an 750 to 1800mm telephoto lens, or the ATX/STX 95mm spotting scopes into a 900mm to 2100mm telephoto lens. The effective focal length depends on size of camera chip, and scope zoom factor.

The TLS APO employs a 30mm pancake lens, as recommended by Clay Taylor from Swarovski Optik USA (an American naturalist), which when coupled with the Swarovski eyepiece produces razor-sharp images with excellent field characteristics.

This adapter works on a wide variety of cameras including Digital SLR's (DSLR), micro 4/3rds, and other mirrorless camera bodies (with detachable objective lens), using standard T-ring adapters. We recommend using cameras which produce low noise at higher ISO settings.
