唔知 KM 5D可唔可以用番以前的舊鏡, (如同KM 7D一樣 ), 用舊鏡同新鏡有可分別, 見有評論話會多了1.5X, 咁即係咩,好定唔好, 唔該各位大佬

唔知 KM 5D可唔可以用番以前的舊鏡, (如同KM 7D一樣 ), --> Yes

用舊鏡同新鏡有可分別, --> Some new lens has SSM (like Canon USM) and D (ADI) function, others no diff.

見有評論話會多了1.5X, 咁即係咩,好定唔好
--> Focal lenght will be multiplied by 1.5
e.g. 20mm will become 30mm
not good for wide angle but good for tele
e.g. 200mm -> 300mm
