用緊450d 如果用ff 鏡好似a09 咁鏡頭要x1.6?
非ff 鏡那用不用加乘 好似a16
謝謝ching解答!!

要。

咁咩野鏡先不用加乘??

[wesleyyau]

canon crop 機non-ff 用咩鏡都要乘1.6.. 機o既問題唔關鏡事...

咁啫係佢kit lens都要？？
１８－５５都x1.6 ?
謝

唔係
嗰支kit係EF-S mount
唔使x1.6

[bb1032003]

Wrong, it still needs to x 1.6 so that it will 'look' like the angle of view of a 29 mm - 90 at FF format.

應該咁講,
每支鏡都係show 緊actual focal length.
所以除FF外無機唔洗乘.

[iso_ray]

你+乘

你加乜鏡都要乘

因為crop機既感光原件比135菲林細, FF機既感光原件同135菲林一樣大

IC~
啫係話依家部450d 用咩鏡都要預果x1.6
除非係ff 機

咁點解好似a09 可以玩係ff 機到既??
係因為mount 嗎?

[莫加租]

a16 y 唔可能用係ff 機?

Tamron A09, A16 物理上可以插在FF機, 實際上影出來會起黑角. 根本原本係成象圈細, 專做比APS-C機用, 價錢亦會平D, 唔會死錯人.

CHING, 聽左咁多人o既意見, 知道點解要x1.6 或者咩係crop factor? 自己做D功課研究下啦:
