I bought it. I still have also the EF 50mm f/1.2L USM lens so I did a little comparison:

These are my first photos taken with this lens:

Do I have any conclusions?
Stay away from Christmas lighting, where LEDs give cold light. Why? Becaue in this case this lens generates horrible onion bokeh in full de-focus mode.

I know, I know, it's a similar story like with Zeiss Otus lenses

In my opinion, the weakest point of this lens is its housing. Why?
Look at your copy of the lens. In my copy you can see the joining of two fragments of the housing (this is probably one of the places where the material is welded, second two are located on both sides of the switches). When you squeeze the casing in a specific way (as shown in one of the pictures posted below), you will hear a click type sound.
I hope this is not a factory defect.
Do you have joining of two fragments of the housing in the same place as me, different place or you don't have it at all?
Generally the part of the housing below the MF ring is very flexible and bends under stronger finger pressure. In the EF 50mm f/1.2L USM lens housing is definitely more solid.
