Either you use the goggles and the 50 mm framelines are the correct ones for the lens, or you remove the goggles and the focussing will be off at all distances except infinity. The lens will lock at infinity without the goggles for this very reason.
In other words: you destroyed the functionality of the lens by filing off the frameline lug....Reduced the value to zero too.
Btw, the goggles for the m3 version do not go into the accesory shoe; they fit on the lens.
