The T2 Micro Four Thirds Camera Adapter for TLS APO from Swarovski is a required accessory for converting an ATX/STX, ATS/STS, or ATM/STM series spotting scope into a formidable digiscoping system. The T2 connects to a Micro Four Thirds bayonet mount, then attaches to the TLS APO digiscoping adapter that mounts to the spotting scope viewing assembly.
