Tamron 18-300mm F/3.5-6.3 Di III-A VC VXD 被广泛称赞为索尼APS-C相机的一款多功能全能变焦镜头。用户喜爱其惊人的16.6倍变焦范围、广角端的近摄能力以及扎实的画质，尽管有人指出在70-80mm以上画质变软且自动对焦较慢。该镜头比典型的APS-C镜头更重，但仍被认为便携。少数已验证买家报告长焦端锐度问题和变焦环生涩，但大多数人认为它是替代多支定焦和变焦镜头的出色全能镜头。
优点
- 惊人的16.6倍变焦范围
- 广角端近摄（半微距）
- 良好的画质和色彩还原
- 坚固的机身带防尘防滴
- 有效的防抖（VC）
缺点
- 70-80mm以上画质变软
- 自动对焦比小型变焦慢
- 对APS-C来说又重又大
- 变焦环缩回时生涩
- 两端有中度畸变
