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

佳能 RF 24-50mm f/4.5-6.3 IS STM 镜头因其紧凑的尺寸、轻巧的重量和良好的图像质量而备受赞誉，是一款多功能且不显眼的旅行伴侣。用户欣赏其性价比，尤其是与相机捆绑购买时，并认为它适合休闲外出、云台工作和人像摄影。然而，一些人注意到它在变焦时会显著伸长，这可能令人惊讶，而塑料卡口和挑剔的镜头盖是次要缺点。总体而言，对于想要一个小型全画幅变焦镜头而又不想携带 L 系列镜头笨重体积的人来说，这是一个很棒的预算友好型选择。
优点
- 紧凑轻巧的设计
- 价格合理的良好图像质量
- 适合旅行的多功能变焦范围
- 不显眼的外观
- 与相机捆绑时性价比极高
缺点
- 变焦时显著伸长
- 塑料卡口感觉廉价
- 令人沮丧的镜头盖设计
- 小光圈导致虚化有限
- 跌落时卡扣系统易裂
