You guys are going to love your lens. Check to make sure your copy is sharp. It should be tack sharp if it's a good one. I exchanged the first one I got and I'm beyond happy with the second.
Regarding Onion Bokeh: they are still there for some subjects.
It doesn’t happen all the time as it depends on the background....however for well defined contrasty specural highlights I can see onions.
Can post something later.
I've been lurking here for a few months, learning bits and bobs about photography and drooling over pictures posted in this thread.
Today I received my copy of the lens and went for a quick walk, I am mostly happy with the performance (which doesn't say much as I am very much a newbie), but I would like to double check with fellow forumites if the amount of distortion I am seeing is expected.
The uncorrected image:
And the image corrected by the lens profile that came with Capture One Pro 12:
I am not too sure what to think, it still looks pretty distorted even after moving the slider from 100 to 0.
I chose another picture from my short stroll today, uncorrected:
And corrected:
Does this seem more in line with people's expectations? I am a bit surprised, it looks like barrel distortion to me but a while back in this thread someone reported pincushion.
On another note my brand new one came in today. This is really my 2nd copy of this lens . I sold my first one a couple months ago. Yea yea I had a wild hair. Anyway I did test for onion rings and sure enough they are there. I’ll post my test. Actually it’s not horrible but not great either, I’m picky too.
Side note I’m very excited since on 2 lenses I was able to make them smaller foot print in my bag the CV 21 and Leica 75 it made more room for my 40 now. Now my PEak Design holds 4 lenses nice and comfortable now.

I concur you need a better wall. It also looks to me like you are looking up at the wall, and it needs to be a straight-on level shot when looking for distortion.
With Capture One v12 and this lens, I have found the "Manufacturer Profile" preferable to the one provided by Phase One, which to my eye seemed to introduce its own distortion. So you might try that and see what you think.

I also think the profile in Capture One for this 40/1.2 (E-mount) is doing something wrong, it seems to add quite noticeable distortion. I switched back to using "Manufacturer Profile" for this lens as well in C1 Pro. The manufacturer profile seems to match the corrections that are done in OOC JPEGs when distortion correction is set to Auto in Camera and those results look much better for this lens.
I noticed the problem since the CV profile was first added on C1 Pro 11.x but I haven't checked it again on C1 Pro 12 yet though.
just be sure it's not just another brick in the wall.

Thank you gents, I will retest and report back. Meanwhile, I have opened a support ticket with Phase One inquiring about an updated lens profile.
Okay just tested my CV 40 1.2 . Starters DO NOT use the profile in C1. Its totally distorted, not sure why the heck that is. So select Manufactures profile for sure for your first image than do a select all than do a copy adjustments and apply adjustments out of the gate to your whole file. Than your done screwing with that. Its very close you could go in and work the distortion slider if you want to get critical.
Second news of the day. i got a extremely good copy
My notes
Interesting even at 2.8 the corners look outstanding but to the very very extremes F5.6 but seriously F4 is perfect. At F6.3 its diffracting. So its that good. On center test 1.2 is 1.2 but 1.6 is magic with that little extra contrast boast and 1.4 totally very very good. This one is a winner copy
Sunstars are starting at 2.8 and almost all CA stuff is gone at 2.8. All this equals a perfect copy of the CV 40
