索尼 FE 28-70mm F3.5-5.6 OSS 套机镜头因其出色的性价比而广受赞誉，提供令人惊讶的清晰度、安静的自动对焦以及紧凑轻便的设计。许多用户认为它足以满足日常摄影需求，尤其是在收缩光圈时，尽管它在弱光下表现不佳，并且在广角端显得柔和。一个反复出现的抱怨是在强光下出现明显的眩光和色彩暗淡，有些人认为它无法充分发挥相机传感器的潜力。总体而言，它被视为一款出色的入门或旅行镜头，但不能替代高端光学镜头。
优点

- 令人惊讶的清晰画质
- 紧凑轻巧的设计
- 安静快速的自动对焦
- 防尘防潮
缺点
- 28mm 广角端边缘画质偏软
- 强光下明显眩光
- 阳光下色彩暗淡
- 光圈小限制弱光使用
- 对高分辨率传感器不够锐利
