Olympus TCON-14B 1.45 Tele Conversion Lens (E10, E20N) Review

The Olympus TCON-14B is a 1.45x tele conversion lens designed exclusively for the Olympus E-10 and E-20N digital cameras. It screws onto the camera's lens and extends the focal length to a 35mm-equivalent 200mm at f/2.4, offering a meaningful reach boost for telephoto work. The metal body construction suggests durability, and its availability as a used item at $11 makes it an inexpensive way to extend the range of these legacy camera systems. This lens is strictly for owners of the E-10 or E-20N, two cameras that were released in the early 2000s and have long since been discontinued. For those still shooting with these models, the TCON-14B remains a practical accessory to increase telephoto reach without investing in a full lens system upgrade.
