这款镜头因其性价比和画质而受到称赞，尤其适合人像和采访拍摄。用户喜欢它的虚化效果、色彩还原以及f/2.2下的梦幻外观，尽管自动对焦比其他一些镜头慢，并且在视频模式下有一个小的重置问题。它是一款APS-C镜头，因此全画幅用户需要使用Super 35模式。
优点
- 价格实惠
- 出色的虚化效果
- 良好的自动对焦
- 美丽的色彩还原
- f/2.2下的梦幻外观
缺点
- 自动对焦比75mm慢
- 视频模式重置问题
- 仅APS-C，非全画幅

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。
优点
- 全焦段成像锐利
- 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
- 对 APS-C 机身而言太重太大
- 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
