Canon EF S 鏡設計上是用於 1.6X上? 但可用在 全篇幅 or 1.3X 機上嗎?

若 EF S 鏡 (例如: EF S 10-22mm) 用於 1.3X 機上,

在 wide 時是否會有黑角或黑邊情况出現呢??

Thanks.

EF S 鏡唔可以用在 1Ds, 1D, 5D，只可以用在 1.6X 機身上

理論上插唔入﹐改o左 mount 都應該有黑角。

Well, it depends on the black unit at the back of the lens I have Sigma 10-20 and try it on a old EOS film camera it is ok. The different is if there is an element extended from the back into the camera body then it can't be use as mentioned before the mirror will be obstructed by the extended portion of the len.

But there is no extended portion it can be use but black corner will be find in some focal length on the wide end.

Simply check and compare the len mount side of an EF-S len with a EF len if the black element at the len mount side are similar in shape the EF-S len can be used on FF or 1.3 but with black corners.
