Just bought a lens from a fellow CSer, happy with its sharpness, but got one problem:
the actual focusing point is always behind where my camera is aimed at, in simple words - misfocus.
I want to know whether it's my camera's problem or the lens'. Initially I thought it's the lens' fault, because I have never had this misfocusing problem before with other lenses.
However, after some study, I begin to doubt theoratically the lens itself is able to "misfocus" at all! I mean, the lens is always doing what the body tells it to do, the lens is always focusing and giving the body the perfect point, just that the body gives wrong info on where to focus accurately. Am I right?
Really hope someone here share their explanations. Thanks in advance!
