中古 Nikon TC-201 2X テレコンバーター AI-S マニュアルフォーカス

For the price of a single modern lens I get double the reach on my old 50mm, and the glass is still incredibly sharp even wide open. The focus ring turns smooth and damped, just like my other AI-S gear, and it locks onto the body with zero play.

The all-metal mount feels reassuringly solid compared to modern plastic ones. Paired with my 200mm f/4, I'm getting sharp results that surprised me for a used teleconverter.

Glass is spotless and the mount is tight as a drum, so it feels like a fresh piece even though it's used. Doubling my 105mm to 210mm for manual focus shots is exactly what I needed, and the AI-S coupling works perfectly on my camera.
