<I'm just wondering that adding MD-12 to my FE and FM2n can improve: - handling convenience - stability - reduce shake (miror rebound) especially in slow speed> I own the FM2n + MD-12 combo (it's my main 35mm system). I am left-eyed and find the motor indispensible. It is the only way I can shoot & wind without having to move my face away from the finder. It does however add weight. Each motor weighs in the neighborhood of 1 lb. regards, Henry Posner/B&H Photo-Video http://www.bhphotovideo.com
