ソニー FE 100-400mm f/4.5-5.6 GM OSSレンズ

The zoom ring is incredibly smooth, and having that 100-400mm range in a single lens makes wildlife shooting so much easier. The autofocus locks on fast, even with birds in flight.

I was worried about the weight, but the magnesium alloy build actually makes it manageable for a day of wildlife shooting. The zoom ring tension is adjustable, which let me fine-tune it for fast-moving subjects.

The dual optical stabilization in this lens makes handheld shots at 400mm incredibly sharp, even in late afternoon light. Focus locks onto birds instantly, and the zoom ring tension is adjustable which I found really useful when panning.
