二手 Canon 70-300mm F4-5.6 L IS USM 鏡頭

The zoom ring is silky smooth, and the autofocus snaps onto birds in flight faster than I expected from a used lens. Even wide open at 300mm, the image quality is sharp enough for my sports shots. This glass is built like a tank and feels solid in the hand.

I was a bit nervous buying a used L-series lens, but the autofocus is lightning fast and the images are tack sharp even at 300mm. The build quality feels reassuringly solid, perfect for the muddy sidelines of my kid's soccer games.

Picked this up used, and the image stabilization is seriously impressive for handheld shooting at 300mm. Even in mediocre light at a local soccer game, the autofocus locked on quickly and the shots came out sharp.
