Sony FE SEL2070G 20-70mm
Its unprecedented 20-70mm zoom range starts at an ultra-wide 20mm, a first for a standard f/4 zoom, paired with a constant f/4 aperture and a lightweight 488g, weather-sealed build. The lens delivers outstanding G-series resolution across the frame and refined video performance with minimized focus breathing, while its 0.39x maximum magnification offers excellent close-up capability throughout the zoom range. This is the ideal single-lens solution for travel photographers and hybrid shooters who need wide landscapes and standard framing without swapping optics.

竞品对比
价格区间收窄到 $1040 到 $10936，竞争格局也变了。Sony E 11mm F1.8 在超广角端更轻更便宜，Tamron 17-70mm f/2.8 带防抖还便宜，Sigma 28-70mm f/2.8 体积小一圈，Nikon Z 17-28mm f/2.8 画质接近但更轻，Panasonic Leica 12-35mm 在 M43 系统里更小巧。这款镜头现在夹在中间，优势没以前那么明显。

价格
性价比分析
价格没涨，但分数从 93 掉到 81，说明性价比感知变差了。$1040 起步价在同类里不算便宜，尤其 Tamron 和 Sigma 的 f/2.8 变焦都更亲民。除非你特别需要这个焦段和光圈组合，否则现在这个价位有点尴尬。

最终评价
分数下滑到 81，主要因为新对手太强。镜头本身没变差，但市场变了。如果你已经入手，继续用没问题。如果还在观望，建议先看看 Tamron 17-70mm 和 Sigma 28-70mm，它们可能更划算。
