シグマ 70-200mm f2.8 DG DN OS (S) ソニー E マウント

I was able to shoot handheld in dim light at a wedding and the OS stabilization kept every frame sharp, even at 200mm. The constant f2.8 aperture really gives you flexibility without needing to swap lenses.

The f2.8 constant aperture is a lifesaver in low light—I shot an indoor wedding with it on my a7 IV and didn’t need to touch ISO past 3200. The build feels solid enough to survive a few knocks, and the zoom ring is buttery smooth.

The autofocus locks onto birds mid-flight faster than I expected, and the constant f2.8 keeps everything sharp even in dull winter light. It’s heavy, but the zoom ring is so smooth that I forgot about the weight during a whole day of shooting.
