Four Thirds (4/3) f2.8 14-54 on E-M5 AF speed

For less than $125. including a $33. adapter I have a high quality f2.8 zoom that's equal if not better IQ and build quality than the native 12-40. Yes, it's bigger and heavier and slower AF but for 1/8 the price I can live with that. Even on the E-M5 the non-SWD 14-54 locks focus in 3 sec. On the E-M1 it should be almost as fast as native. Here's a demonstration of focus speed.
