这款腾龙70-300mm镜头因其出色的性价比而广受好评，以实惠的价格提供了可靠的远摄和微距性能。许多用户强调中距离和微距下的清晰度，但也有一些用户指出长焦端画质偏软，以及在高对比度场景中明显的色差。做工在同价位中不错，变焦环顺滑，金属卡口，但少数评论者反映对焦不稳定，变焦环有轻微卡顿。总体而言，对于能接受其局限性的用户，这是一款非常推荐的平价远摄镜头。
优点
- 性价比极高
- 微距性能良好（1:2）
- 同价位做工扎实
- 中距离和微距成像锐利
- 自动对焦快速准确
缺点
- 300mm端画质偏软
- 明显的色差
- 变焦环在180-200mm附近有卡顿
- 在某些机身上对焦不稳定
- 不如高端镜头锐利
