CANON 的SLR 機EOS30V是用EF接環,而DSLR機EOS20D是用EF或EF-S接環,Nikon D70 是用Nikon F mount,但為何我在dcfever中看到的Sigma AF鏡頭,它說能適合 AF 接環 : 適馬、佳能、尼康D (以上皆配合 HSM 超聲速馬達)、美能達、賓得?
不是不同的接環嗎?
還有,想問問那麼是不是使用EF接環的鏡頭的所有功能都能EOS30V和EOS20D中使

Sigma have produced different mounts lenses for different cameras and the mount is fix. i.e. if you have bought a sigma 24-70mm lens to fit on your Canon 20D, this lens can only be used on Canon camera. If you want to fit it on a Nikon camera, no way. Please buy another lens with Nikon mount.
ok?
