I received an M4-P recently, very happy about that.
I have a summicron 35 and summitar 50.
The 35/135mm bright lines appear in the viewfinder. When I put the 50 on, the bright lines do not change. Is it because the summitar is too old?
Any guidance for a newbie would be much appreciated.
I don't have another M lens to test the bright lines with.
