중고 Sony FE 100-400mm F4.5-5.6 GM OSS 렌즈

I was a bit nervous buying a used lens, but this 100-400mm arrived looking practically new with no scratches on the glass, and the zoom ring is smooth as butter. It's already paid off getting sharp wildlife shots at the full 400mm range.

The autofocus locks on so fast at 400mm that I caught birds mid-flight without hunting through the frame. The zoom ring has a nice, damped feel that makes fine adjustments easy. Being a used copy, there's a tiny bit of wear on the barrel, but the glass is flawless and images stay tack sharp edge to

I’m honestly impressed with the build quality for a used lens; the autofocus is still snappy and quiet, even at the 400mm end. Paired with my a7III, it locks onto birds in flight without hesitation.
