二手 Sigma 50-100mm F1.8 DC 鏡頭（Nikon用）

Picked this up used and the autofocus is snappy, definitely faster than I expected for a third-party lens. The f/1.8 aperture throughout the zoom range is a game-changer for indoor sports shots.

The 50-100mm f/1.8 is exactly the sharpness monster I hoped for, and even used it feels solid with the tripod foot included. The hood and caps were all there, and the 100-day warranty gives me some peace of mind on a secondhand lens. Focus is quick enough for my sports shots, and the bokeh is creamy

Bought this used lens and the glass is spotless, plus the tripod foot came included which saves a hassle. It’s heavy as expected for an f/1.8 zoom, but the sharpness at 50mm wide open makes it worth the shoulder workout.
