iPhone5s比我的卡片相机好多了。而且，由于iPhone5s还让我可以编辑和分享照片，这部手机还常常替代了我价格更高的可换镜头单反相机——数周来我都没有找到给这台单反相机充电的理由。

The 5s is far better than my point-and-shoot , and because it lets me edit and share my pictures , it is often superior to my expensive , interchangeable-lens SLR ( whose battery I haven 't had reason to charge in weeks ) .

数码相机大致可分为四大类：口袋机（pocket-size）、傻瓜机（point-and-shoot）、高倍数或超级变焦相机（super-ormega-zooms）以及数码单反相机（D-SLRs）。
