Viltrox AF 28mm f/4.5 饼干镜头因其超紧凑的尺寸、轻巧的设计和出色的性价比而广受好评，成为街头摄影和旅行的最爱。用户指出，它将全画幅相机变成了一个非常便携的设置，尽管固定光圈 f/4.5 和缺乏手动对焦环对某些人来说是限制。图像质量被认为物有所值，但弱光性能和暗光下的自动对焦是常见的缺点。少数用户报告了后镜头盖卡住或某些索尼型号电池耗尽的问题，但总体情绪对其预期的休闲用途是积极的。

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。

- 广角端近摄（半微距）

- 对APS-C来说又重又大
- 变焦环缩回时生涩
- 两端有中度畸变
