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

The glass is clean and the focus ring turns buttery smooth—exactly what you want from a used manual-focus piece. Bolted it onto my 105mm f/2.5 and the 2X reach feels rock solid, no wobble at the mount. Slightly heavy, but that’s the trade-off for real Nikon optics that still hold their own.

Used this on my 300mm f/4.5 and the image quality stayed surprisingly sharp even wide open. The manual focus ring feels smooth and precise, no looseness at all.

Paired this with my 105mm f/2.5 and the combination locks focus solidly; the optics are clear with no haze, so image quality holds up even at 2x magnification.
