Digital cameras have one of four types of lenses:
1) Fixed-focus, fixed-zoom lenses - These are the kinds of lenses on disposable and inexpensive film cameras -- inexpensive and great for snapshots, but fairly limited.
2) Optical-zoom lenses with automatic focus - Similar to the lens on a video camcorder; these have "wide" and "telephoto" options and automatic focus. The camera may or may not support manual focus. These actually change the focal length of the lens rather than just magnifying the information that hits the sensor.
3) Digital-zoom lenses - With digital zoom, the camera takes pixels from the center of the image sensor and interpolates them to make a full-sized image. Depending on the resolution of the image and the sensor, this approach may create a grainy or fuzzy image. You can manually do the same thing with image processing software -- simply snap a picture, cut out the center and magnify it.
4) Replaceable lens systems -- These

数码相机一般配有以下4种镜头中的一种
1.固定焦距，固定变焦镜头---可抛弃式和廉价的胶卷相机一般配制此种镜头---有点是廉价和有利于快照，但是功能很有限
2.自动变焦的光学变焦镜头-类似于摄像机的镜头，具有广角和远距功能和自动对焦功能。此类相机也许会支持手动对焦。此种镜头是真实的改变镜头的焦距，而不是对光学传感器所得到的信息进行增益。
3.数码变焦镜头-相机从图像传感器中取得各种像素，然后得到一整幅图像。这种方法所得图像是精细还是模糊取决于传感器的分辨率。你也可以用处理软件对相片进行同样的处理---只要简单的按下镜头，拷出照片，修改它。
4.可更换镜头系统---类似于35mm相机上的可更换镜头。一些数码相机可使用35mm的镜头。
希望对你有帮助，觉得可以就对给点分哦,hehe
数码相机机有四种类型的镜头：
1）固定焦距，固定变焦镜头——这些种类的镜头适用于一次性的且价格便宜的胶片照相机——价格便宜非常适合拍摄，但相当有限。
2）光学变焦镜头用于自动聚焦——类似于录像摄像机，这些镜头有“大范围”和“远距离摄像”以及自动聚焦的选择。照相机可能会或可能不会支持手动对焦。这些实际上改变了镜头的焦距而不是仅仅放大传感器采样数的信息资料。
3）数字变焦镜头——适用于数字变焦，照相机降低了摄像传感器中心像素并且把它们修改成实际大小的图像。这要取决于图像与传感器的分辨力，此方法也许会产生粒状或模糊影像。你也可以运用图像处理软件亲自动手做出同样的效果——简单拍张图片，删掉中心部分然后放大它。
4）可更换镜头系统——这些类似于35毫米摄像机的可更换镜头。有些数码相机能运用35毫米摄像镜头。
