如果不考虑FD以前的卡口来说,佳能现在的主流镜头一共有三种卡口:
1、EF卡口镜头:通用性最好,能够用于现今佳能的所有型号主流单反相机。而且目前绝大多数佳能镜头都使用EF卡口
2、EF-S卡口镜头:通用性稍差,专门为APS-C幅面(有人称之半幅或残幅)的数码单反设计,于2003年推出,只能用于APS-C幅面的数码相机,无法用于全幅相机
3、EF-M卡口镜头:通用性最差,专门为无反光板可换镜头的数码相机设计(俗称微单),于2012年推出,只能用于EOS-M系列相机
对于上述三种卡口的适应性,可作以下概括:
1、EF卡口的相机,对于镜头的通用性相对来说最差,只能使用EF卡口的镜头,但是目前绝大多数镜头,尤其高端镜头都是EF卡口的。这类相机大多数为全画幅相机,代表机型有1Ds系列、1DX、5D系列、6D;其次,1D系列虽非全幅(APS-H幅面),但亦必须用EF镜头;再次,佳能早期的APS-C幅机型(2003年之前),因EF-S卡口尚未问世,亦只能使用EF镜头,代表机型有D30、D60、10D
2、EF-S卡口的相机,对于镜头的通用性很强,除可以使用全部的EF镜头外,亦可以使用全部EF-S卡口的镜头,但无论在使用何种镜头,实际焦距均相当于镜头焦距的1.6倍。这类相机均为2003年以后的APS-C幅面相机,代表机型有:7D、70D、700D、1100D等绝大多数佳能在售的入门级相机
3、EF-M卡口的相机,在某种意义上对于镜头的通用性是最强的,除了可以使用与之匹配的EF-M镜头外,也可以加装转接环,使用全数EF和EF-S镜头,焦距转换系数亦为1.6。目前只有佳能的无反相机使用(其实即微单,只是因为微单这个名称被索尼注册了,别家不能再用),代表机型:EOS-M以及EOS-M2
EF 镜头是通用的,EF-S 镜头只能在APS-C画幅的机身上用。
各家的镜头只在自家的机身通用,比如尼康的镜头不能用在佳能的机身上。
但转接环可以转换镜头接口实现不同镜头和机身的对接。
因技术的革新,各家不同时期的接口也会改变。
不同品牌接口都不一样的,就是同一品牌也会有不同时期就是同一时期都会有不同的接口镜头,说明书上都会有的,但是可以使用转接环,注意什么镜头都可以转佳能,其它要看情况,但是转后就是手动头啦。
不是~~以前手动胶片单反机的镜头就不通用,现代的自动胶片单反和自动数码单反就通用~~
