I recommend looking up the reviews on Google for samples as they will probably have done it properly. But I have just done my very basic test, scoring the sharpness at close range and at infinity. The results are what the reviews say. But I feel like because I am into vintage lenses, what they said in the reviews made me expect worse e.g. ghosting/glowing wide open.
|the 7Artisans 35mm f1.2 is perfect for lowlight and nights out|
The lens does ghost/glow wide open but it is much less than my Super Takumar 50mm at f1.4. The Tak is sharper, but last night I used the 35 in street photo focal lengths and it was much less noticeable. I felt like there was no problem using at f1.2, whereas I always want to stop the bigger f1.4 down to f1.8 or f2.
The resolution/sharpness of the lens is low, like they say in the reviews. At f1.4 the Super Tak is clearly much sharper. However, the 35 scored slightly higher because of the lack of the glow. I remember commenting last night that at f1.2 the 35 is more like the beautifying effect (clarity turned down), which for people seems fine. Will be using on the street in the day soon. So might have more to say about this.
7Artisans 35mm f1.2 Bokeh Example
The bokeh is unique and has its own character, see the yellow shot below. It is not ultra smooth but it is heavy and has it's own "look".

Where is the 7Artisans 35mm f1.2 Best?
The 35 is sharpest at f5.6 and f8 where it is about the same sharpness as my Fuji 16-50mm II kit zoom i.e. perfectly acceptable. I gave it 7+ out of 10 and -8 at f8 for sharpness. But it is usable wide open at f1.2 as I gave it -6/10 which is my baseline for acceptability.
After owning this lens for quite a while I have sold it. I just couldn't be bothered manually focusing it and just didn't use it enough. Plus I have started using the Fuji 27mm f2.8 pancake which isn't much wider and isn't much more expensive. But I am into street photography. If you are into portraits then the 7Artisans 35mm f1.2 will be a great choice.
I will still be keeping other manual lenses which are easier to focus like the Minolta Rokkor PF 55mm f1.8. Or cuter like the Industar 69 28mm f2.8 which I use hyperfocal focusing for at f11, despite it being optically inferior. The 7Artisans beats most of my vintage lenses and is the only f1.2.

I wouldn't use this lens on landscape or anything else where sharpness is critical. I would use it for portraits as the lack of sharpness isn't too bad and the the thinner DOF gives subjects great subject separation.
It is definitely worth considering at the current $145 price tag. I sold mine for $80 and it went too fast (I undervalued it). Probably should have been $95 used in mint condition.
