중고 Olympus EC-20 2x 텔레컨버터 4/3 (M43 시스템 비호환)

The glass is spotless and the contacts are clean, exactly what you want from a used converter. Mounted it on my 4/3 lens and the autofocus still locks on fine, though it does hunt a bit in low light. For the price, it's a solid way to double your reach without buying a new lens.

I've been using this 2x tele converter with my 4/3 lenses and the image quality is surprisingly sharp for a used piece of gear. The build feels solid and it clicks into place perfectly, no wobble at all. Exactly what I needed to double my reach without breaking the bank.

Was a little nervous buying used optics, but this tele converter is optically perfect with no scratches or haze. Doubled my reach on the 40-150mm nicely for wildlife shots. Really glad I took the chance on it.
