适马500mm f/4 Sports镜头因其锐度、快速自动对焦和坚固的做工而广受好评。用户表示，通过FTZ转接环，它与尼康Z系列相机配合良好，在野生动物和鸟类摄影中，尤其是在弱光环境下，能提供出色的画质。有人提醒，长时间手持拍摄会有点重，但大多数人认为它平衡性不错。这款镜头被视为昂贵原厂定焦镜头的高性价比替代品，还能通过适马镜头底座进行自定义设置。
优点
- 图像锐利
- 快速准确的自动对焦
- 做工扎实
- 弱光表现优秀
- 平衡性良好
缺点

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

- 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
