二手 Sigma 50-100mm F1.8 DC 鏡頭（Nikon用）

Picked this up used for portraits and that constant f/1.8 across the zoom range really lets in light, even in dim studios. The tripod foot feels solid, no wobble. Came with the hood and caps like described.

The tripod foot alone makes this worth it — solid metal, mounts perfectly, and the f/1.8 at 100mm gives that creamy background separation I was after. Glass is spotless, caps and hood all included, and the 100-day warranty takes the edge off buying used.

Bought this as a used lens and the glass is spotless, plus the tripod foot and hood arrived exactly as pictured. The f/1.8 at 100mm gives that creamy background separation I've been chasing, and the 100-day warranty is a nice safety net.
