I have a strange issue with my canon ef 40 STM while focusing manually.
You can see the issue on 200% part of picture here:

you need to roll over the image or out to see the difference.
The picture is moved slightly. This move was cause depending if I set the focus turning MF ring from infinity to close, or the other way round.
I have checked on 50 1.8 and EF-S 18-55IS and such situationi does not appear.
Is my lens faulty?
thanks,
Chris
