The Olympus tele conversion lens increases the existing focal length by factor of 1.7 but without changing the aperture. Therefore it is possible to enjoy the high brightness even for far away motifs. The TCON‑17X is compatible with XZ‑1, XZ‑2 and STYLUS 1 series. Depending on the camera model used, a special conversion lens adapter is required; in case of the XZ‑1 & XZ‑2 it is the CLA‑12, for the STYLUS 1 it is the CLA‑13.
