Certainly not perfect. What matters however is the the final image quality after software correction (in camera/ in Raw converter). If the lens delivers a sufficently high border/corner distortion, the quality loss caused by the distortion correction may not be of much concern and the final image quality could still be better than competing offers.
What counts in the end is the final image. Nowadys distotion corrects in any decent raw converter with a good lens profile automatically.
This is why I trade less distortion for better border resolution anyday. if your subject doent show the distortion you dont need to correct it and you end up with an even image.

Well, the associated interpolation has a negative impact on the MTFs at 12mm. It is a lossy procedure which is clearly recognized by Imatest (see the early Samsung tests where I measured both). Normally I would rather measure the RAW data but in MFT land you don't really have a serious choice.
