Realised that my M42 lens has issue when focusing at inifity,subject which are more than 1metres away cannot be focused.
I'm using the M42 adaptor for sony/minolta and various cause of the problem i heard is that this common issue is attributed to the thickness of the M42 adaptor.
Have actually gotton some advises from other bros but i would like to understand more.
1)sandpaper it which i heard is being done by certain people..messy job though.
2)get a more expensive adaptor...they are more expensive for a reason right?
