Judging from the published crops, cameralabs does not focus very precisely in their sharpness tests, and lenstip does the same as OL (focussing again for every tested area). So, I will trust lenstip results more than cameralab findings.

The Z 35mm LoCA is quite severe by the way (see the cameralabs sample images), for a modern 35mm f1.8 lens. Looks like my EF 35mm f2 (introduced in 1990).

 CameraLab's copy was de-centered BTW.
