live view focus got nothing to do with VF focus .
In reply to liukaitc, Aug 27, 2012

LV focus is contrast based directly from sensor , it will always be the most accurate , but slow.

VF focus is phase detect focus , and its measured from the focusing screen at the bottom of the camera .

just because you get perfect focus with LV doesnt mean your lens is fine . it just means that the motor inside the lens "works" .
try with a different lens first , canon lens will be best .
