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

佳能RF 24-105mm f/4-7.1 IS STM镜头被广泛称赞为一款轻便、多功能的套机镜头，以其价格提供了清晰的图像和有效的防抖。许多用户欣赏其旅行和日常使用的价值，尽管一些人注意到24mm处有明显的畸变和暗角、光圈较慢以及微距能力有限。它被视为一个坚实的入门级选择，但不能替代L系列或定焦镜头。
优点
- 轻巧紧凑
- 图像清晰
- 有效防抖
- 多功能变焦范围
- 性价比高
缺点
- 光圈较慢（f/4-7.1）
- 24mm处明显畸变
- 广角端暗角
- 校正后边缘柔软
- 真正的微距能力有限
