Olympus E-PL1 Micro 4/3 轉接環

Micro 4/3 have many different kinds of 轉接環, but all of them (except 4/3) have no af. also, you can only use m mode when you use 轉接環. some 轉接環have aperture control inside the轉接環 so you can still control the aperture with a real aperature ring. if you really want to buy a 天涯鏡, you must be careful because m43 have to x2 but most lens is for apsc.
