Everything is compromise in life:
You're apparently right about Sonnars being distortion free.
trouble is, they bring with them focus shift and limited min focus.
it may sound like I'm looking for the summilux asph, but paying 2000$ (over the cron I have) for my very occasional use of 1.4 is way past silly.
The canon/Nokton may well be the best compromise for me. Haven't decided yet. I just wanted to check the Nokton in that regard, to see if it was distortion free, and unfortunately it's not.
