Big Mike's SLY500 500mm
62 满分 100 置信度低 8 条评价
这款廉价长焦镜头收到了褒贬不一的评价。许多用户称赞其性价比，指出对于偶尔使用（如拍摄月亮）来说，对焦清晰，画质尚可。然而，几位经过验证的买家报告了对焦偏软、灰尘污染和做工质量差的问题，尤其是在使用2倍增距镜时。它最适合那些有现实期望并愿意使用三脚架和手动对焦的用户。
优点
- 性价比极高
- 偶尔使用对焦清晰
- 三脚架上画质尚可
- 适合拍摄月亮和日食
- 适配器和转换器加工牢固
缺点
- 部分产品对焦偏软
- 2倍增距镜导致灰尘污染
- 需要大量光线（最大光圈f/8）
- 无防抖功能
- 适配器缺少后盖
