I ask canon company , they said 5D cant use canon digtal lens, how about the other Tamron or Sigma??

[hanny]

digital lens is meaning low level and smaller size of the lens <inside>

of cos 5d can not
all the digital are can not use on it <tamron/sigma of dc or di2 all can not>

you must use the one only call <ef> for film machine use

[cfans]

我想問問樓WHAT IS THE MEANING OF Digtal Lens?
是否指EF-S MOUNT ?
因為 5D 係 FF SIZE 用唔到 EF-S D 鏡頭係正常

[hanny]

digital is ef-s

咁樣拗並無意思，跟本大家digital lens的定義不同。

因為5D唔需要crop x1.6, 所以用唔到比135細成像圈嘅"閹"鏡

"閹"鏡包括:
Canon -- EFS
Tamron -- Di II
Sigma -- DC
Tokina -- DX
Nikon -- DX
KM / Sony -- DT
Pentax -- DA
OM 4/3 -- 所有

用"閹"鏡, 後果如下
