佳能EF-S 18-135mm f/3.5-5.6 IS STM镜头被广泛称赞为APS-C相机上多功能的全能旅行镜头。用户一致强调其安静流畅的STM自动对焦、有效的图像稳定以及覆盖从广角到中长焦的实用变焦范围。虽然对于套机镜头来说画质被认为非常好，但一些评论者指出在极端焦距下画质偏软、18mm处有桶形畸变，以及可变光圈限制了弱光性能。做工被描述为以塑料为主但尚可，不过电子对焦环和偶尔发涩的变焦环受到了批评。
优点
- 安静流畅的STM自动对焦
- 有效的图像稳定
- 多功能的18-135mm变焦范围
- 套机镜头中良好的画质
- 轻巧紧凑的设计
缺点
- 极端焦距下画质偏软
- 18mm处桶形畸变
- 可变光圈限制弱光使用
- 电子对焦环
- 塑料机身感觉廉价
