佳能EF-S 17-55mm f/2.8 IS USM因其出色的图像质量、快速恒定光圈和有效的防抖功能而广受赞誉，是APS-C画幅用户喜爱的全能镜头。然而，许多用户报告了严重的进灰问题、镜头垂头和与其高昂价格不符的做工质量。虽然光学性能媲美L系列镜头，但缺乏防尘防滴密封以及随着时间的推移偶尔出现的自动对焦或防抖故障是常见的痛点。总体而言，它是一款光学性能出色但耐用性存在明显问题的镜头。
优点

- 快速恒定f/2.8光圈
- 有效的图像稳定（3档）
- 适用于APS-C的17-55mm多功能焦段
- 快速安静的USM自动对焦
缺点
- 镜头内部严重进灰
- 长时间使用后镜头垂头
- 无防尘防滴密封
