Zunows THC-19 Tele Converter is an excellent way to extend the reach of your zoom. It attaches quickly to the front of the lens, shifting focal length range in the telephoto direction. Unlike most external teleextenders, the THC-19 tele converter requires no exposure compensation and will add a 1.9x magnification onto your standard lens.
The THC-19 has been thoughtfully constructed without sacrificing quality. Manufactured in Japan, the craftsmanship is meticulous in every detail and the materials used are of the finest grade available. The THC-19 is produced according to the strict regulations of the Japanese Industrial Standards (J.I.S.). This guarantees the standard of quality and published specifications.

I use this lens for long distance outdoor action video (snowboarding, surfing, etc.) and it is delivering great images!
