二手 Sigma 17-70mm f2.8-4.5 (PK-A) 鏡頭

The hood and caps all came included, which saved me a trip to the camera shop. Glass is spotless for a used lens and the f2.8 at 17mm gives nice creamy backgrounds for portraits. Focus ring turns smooth, feels like it's barely been used.

Picked this up used and it’s honestly in better shape than some new lenses I’ve handled — the glass is spotless and the zoom ring moves smooth as butter. The f2.8 at the wide end gives me just enough light for indoor shots without flash.

The 100-day warranty gave me peace of mind buying used, and the glass itself is genuinely spotless—no dust or scratches that I can find. The f2.8 at 17mm is sharp enough for indoor shots, and the zoom range covers most of what I need on a daily walk.
