一、广角镜头的概念广角镜头通俗地讲就是焦距较短、视角较大的镜头。对于135单反相机来说,广角镜头一般是指焦距在24~35mm之间的镜头,而超广角镜头的焦距一般在14~20mm之间,使用广角镜头可以获得更加开阔的视野以及宏伟壮观的视觉效果。广角镜头在旅途中使用广泛,和长焦镜头相比具有相反的某些特点。广角镜头携带及使用较方便,体积一般不会过大,在空间有限的地方拍摄或拍摄场面宏大的画面时尤为好用。另外,

For 135 SLR cameras, the wide-angle lens generally refers to the focal length of the lens between 24 ~ 35mm, while the ultra-wide-angle lens focal length is generally 14 ~ 20mm, the use of wide-angle lens can get a broader vision and magnificent visual effects. Wide-angle lenses are widely used on the go and have some of the opposite characteristics of telephoto lenses. Wide-angle lens to carry and use more convenient, the volume is generally not too large, limited space in the area where the filming or shooting scenes especially useful when large images.
