广角镜头是指其焦距比标准镜头的短的摄影镜头,由于其视角范围比标准镜头广,故称为广角镜头,也称短焦距镜头。 广角镜头又分成两类:普通(小)广角镜头和超广角镜头。 对于135画幅而言,广角镜头现有的焦距范围约为14～40mm,视角范围为60~115°,其中焦距自17～21mm的称为超广角镜头;焦距自24～40mm的称为普通广角镜头。...
广角镜头(Wide-angle lens)系视角范围为60度以上的镜头。若为35毫米规格，35毫米、28毫米、24毫米镜头，若为6*6规格，50毫米以下是广角镜头。35毫米规格，20毫米以下称超广角镜头。若为单镜生产反光用的镜头，属于反远距焦点式。与标准镜头相比，景深大和远近感得到夸张，是其特点。当室内建筑物和人物...

The focal length doesn’t directly translate to the angle of view. How much you can actually fit in the frame depends on your camera’s sensor size. For example, a 24 mm lens translates to about 84 degrees of view on a full frame camera. But if you put that same lens on a cropped...
If your standard zoom has an f/2.8 max aperture, you may also desire a fixed focal length/prime wide-angle lens to gain a wider aperture. I very frequently encounter the need for focal lengths wider than those in my standard zoom lens and seldom go on a shoot without having the wide...
