Plenty of people have posted photos...or are you being sarcastic and I didn't get it?
I see that you own the 1.2. I am referring to the 1.4.
I'm referring to the 1.2, which while not know for having perfect distortion correction, it's not known for being abnormal.....such as the 1.4.
It is out of production, and not many come up for sale.
That's because the owners tend to hold onto them. Like me.
... minimum focus distance maybe? all I've got are screwmount lenses right now and that 1 m thing gets really annoying.
Both 1.2 and 1.4 have similar levels of distortion. What is known is that people have opinions about lenses without actually trying them - as your post shows. Even the 35/1.4 Summilux ASPH has 2% distortion which comes close. The 1.7 Ultron has less distortion than all three of them.

It's a very fine lens optically. It does not take hard use well however - a bit fragile.I loved mine. I only sold it because it was falling apart.
It performed very well at f/2.8
