二手 Sony FE 28-70mm F2 GM 鏡頭 (Sony E)

The constant f/2 aperture is a lifesaver for indoor events; I can finally shoot at lower ISOs without worrying about noise. The zoom ring feels incredibly smooth, just like a brand-new lens. I'm thrilled with how sharp the images are even wide open.

Third-party autofocus lenses have let me down before, but this used GM zoom locked onto moving subjects instantly during a family shoot — the constant f/2 aperture made indoor shots look effortless. Handled like a much newer lens, and the glass is still crystal clear.

Switching to this used lens was a smart move—the constant f2 aperture lets me shoot indoor events without raising my ISO too much. The focusing feels snappy even on my older body, and it balances perfectly on the camera. A solid workhorse, especially at this used price.
