The Olympus TCON-T01 Teleconverter is a dedicated teleconverter for use with the Olympus TG-1 Waterproof Digital Camera. The Olympus TCON-T01 lets you increase the optical zoom on the TG-1 from 4x to 6.8x for dramatic, vibrant close-ups with a professional background blur. Using the Super-resolution Zoom feature of the TG-1 you can even reach 13.6x magnification. The TCON-T01 Teleconverter is waterproof to 12 meters and is particularly useful when shooting subjects at a distance. In order to attach the T01 Teleconverter to the Olympus TG-1 you will need to purchase the Olympus CLA-T01 Conversion Lens Adapter (available separately).
