So today I tried to get comfortable with M120 I'm shooting this month.
Wide open:
1 step down:
Pixelshift at f8:
Wide open sharpness is the questionable feature with this lens. One step down and it gets a lot sharper, so this is excellent f4 lens
Maybe the widest aperture could've been bit slower, if that would have given better wide open performance. On the other hand wide open can be viewed as soft lens feature. We'll see if I use it as often with this lens as I have been shooting with M100/2.8 and M150/3.5 earlier this year.
