Sigma DG OS 70-300mm f/4-5.6 DG Macro
84 满分 100 置信度中 16 条评价
这款适马70-300mm镜头因其出色的性价比而广受好评，能以实惠的价格提供锐利的图像、漂亮的虚化效果和实用的微距功能。许多用户指出它非常适合业余摄影师，但自动对焦可能较慢且噪音较大，在300mm端不借助三脚架时画质会略有下降。总体而言，对于不需要专业级远摄能力的人来说，这是一款性能与价格完美结合的产品。
优点
- 性价比极高
- 图像锐利
- 虚化效果良好
- 微距功能实用
- 做工扎实
缺点
- 弱光下对焦慢
- 自动对焦马达噪音大
- 300mm端手持画质偏软
- 前组镜片旋转不利于偏振镜
- 长时间携带较重
