The right choice for anyone who appreciates top-quality digiscoping, the TLS APO camera lens was developed as a complete system with the new ATX/STX spotting scopes. Its excellent optical quality makes it particularly attractive to the most discerning digiscopers who want to use system cameras (23mm), APS-C/DX single-lens reflex cameras (30mm) or full-frame cameras (43mm). The TLS APO is supplied without the T2 adapter ring.
