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

佳能RF-S 10-18mm f/4.5-6.3 IS STM镜头因其锐度、紧凑尺寸和出色的性价比而广受赞誉，尤其适用于R7和R50等APS-C相机上的风景和旅行摄影。用户欣赏其图像稳定和安静的自动对焦，但一些人指出，慢光圈限制了在弱光下不使用闪光灯或三脚架时的性能。少数人希望有更近的对焦距离，但总体而言，它被认为是一款多功能、轻便的广角变焦镜头，以其价格提供了令人印象深刻的效果。
优点

- 紧凑轻巧的设计
- 出色的性价比

缺点
