Are you testing distortion correction...... algorithm?

I believe you have made a mistake.
0.6% distortion of Touit 32/1.8 is camera firmware corrected result.
You can refer to
Without distortion correction, the distortion is much higher (-1.8%)
How can you compare lens performance without disabling these correction first?
When mounting on different mounts (e.g. X-Pro1), the measured value will be different due to different algorithm.
I'm not to say Touit 32/1.8 is a bad lens.
I own one. Its image quality is really fantastic (great details, vibrant colors, typical Zeiss pop)!
