In line with Minolta’s practice of labeling products differently in different markets, the lenses were labeled “Rokkor-X” in the North American market, and “Rokkor” throughout the rest of the world. It is noted that apart from this minor cosmetic change there is no difference between the Rokkor and Rokkor-X version of the same lens.
因此兩者應是一樣的,只是不同銷售區域所用的差別標示。
透過MD to 4/3轉接環應該都可轉接到4/3系統。
