二手 Canon EF 400mm F5.6 L USM 鏡頭

I’ve been using this 400mm for two weeks now and the image detail on distant birds is just stunning, even in dim morning light. The lens feels surprisingly well-balanced on my camera body for such a long reach.

Autofocus snaps onto birds mid-flight faster than I can track them, and the reach at 400mm makes distant subjects feel like they're right in front of me. The L-series build feels rock solid in hand, even after years of use.

I've been using this lens for bird photography and the image sharpness even wide open at f/5.6 is impressive for a used piece. The build quality feels solid, and it's lighter than I expected for a 400mm, making handheld shooting much easier.
