腾龙17-70mm f/2.8 Di III-A VC RXD镜头因锐度高、变焦范围广、恒定光圈和有效的防抖性能而广受好评，是APS-C相机的卓越全能镜头。用户赞赏其扎实的做工和性价比，但许多人指出它明显比套机镜头更重更大，在小型机身上会感到头重脚轻。少数评测提到长焦端色散和特定设置下的光圈叶片噪音等小问题，但整体来看评价非常积极。

- 恒定 f/2.8 光圈
- 有效的防抖性能
- 快速静音自动对焦
- 17-70mm 焦段非常实用
缺点

- 50-70mm 端色散明显
- 光圈在 f/5.6 以上有噪音
- 变焦环初始偏紧
- 富士版本没有光圈环

尼康AF-P 18-55mm镜头收到褒贬不一的反馈。许多用户称赞其清晰度、视频模式下的静音自动对焦和轻巧设计，但与较旧的尼康相机（如D5000和D3300，未更新固件）的兼容性问题是一个反复出现的抱怨。一些用户报告了自动对焦完全失效的缺陷产品，而另一些用户则认为它比旧款AF-S镜头在视频拍摄方面有显著改进。
优点
- 清晰的图像质量
- 视频模式下静音自动对焦
- 轻巧紧凑的设计
- 快速自动对焦速度
- 良好的性价比
缺点
- 与较旧相机的兼容性问题
- 部分产品自动对焦故障
- 内部麦克风拾取变焦噪音
- 镜头上没有VR或手动对焦按钮
- 某些相机需要固件更新
