Mine will be too.
Just kept it for the comparison

Thank you!
And yeah, it really is. Contrary to my first assumption field curvature is almost non existent.
That is even more impressive, considering most 35mm 1.4 lenses struggle here.
That is only an assumption of course, I have no insider contact to Sigma
I just agree with you on this. I think that over corrected lenses for SA and CA are not ideal for some applications like portraits for example.
Thanks again for that detailed and skilled comparison. I know the amount of work this stuff takes.

My 35 1.2 had the good idea saturday to just stop autofocusing after maybe 10 actuations at my wedding... I had the Zony not to far away so it had no consequence.
Right now, no one but Sony seems to make 100 % reliable lenses on Sony bodies. At least it's my feeling right now. So I will send it back and ask for a refund and not a replacement. I will wait a few month to see if other people have the same problem (or others) or if I've been very unlucky.

No, I didn't try during the wedding, I had of course other things to do, but I tried today, and no, it doesn't work anymore, at all. The aperture works, but the AF doesn't. I trid everything, switching several times the AF MF button, the AFL button as well. It just doesn't work anymore (I tried on my 2 A9s...) A big disappointment... I had this lens for just one week and probably less than 200 actuations...

Did you switch on/off to see whether it started working again?
That solved issues with the Samyang.
Edit:
Ah, just saw your post. That is unfortunate. Very weird behavior.

very bizarre behavior
dont give up, its an exceptional lens....you clearly just had a bad copy
i went out shooting today for the 3rd time with this lens and it just keeps impressing me with the rendering, totally beyond what i expected

get another copy :-)
I see your point and I don't try to convince anyone who has a functionnal copy to distrust it, but that's not what I'm going to do right now. It makes me angry. I already had a disappointment with my very good copy of the Samyang which gave me some freezes of my cameras, and I've realized that I wasn't the only one with this problem with Samyang lenses. But I kept it because it was not permanent, and nothing that could bother me for a personal trip. But here, it's worse.
I will wait a few month and then check on here, dpreview or other sources to see if this problem (or other problems) happens to other users before maybe buying another sample again...

Could/has anyone tested how good the light-transmission is, perhaps against one of the 1.4's?
If anyone can tell me how to properly measure it I will have a look.
Comparing it to other f/1.4 lenses is inherently pointless in my opinion, as they are just as imperfect in that regard.
But I guess you are referring to this question:
Does it let more light in at f/1.2 compared to 35mm 1.4 Art or 40mm 1.4 Art?
Yes, in the center it does.
Corners are another story though: the 35mm 1.2 I measured at 2.9 EV vignetting in the very corner, the 40mm 1.4 Art at 2.2 EV (those are median values, vignetting in different corners is rarely - if ever - the same).
So effectively in the corners we have a 35mm f/3.5 and a 40mm f/3.1 (this is neither exactly the t-Stop nor the f-Stop, but something in between).

anyone having an issue with this lens in on an a7iii in afc mode? or maybe im doing something wrong. in afc i see the pattern of af points going about, and then somewhere inbetween shooting only the centermost af point works. only retrying the shutter several times does afc begin to work again. i cant easily replicate the problem but it happens at least once every 15 shots or so. very annoying.

There's a German review up on youtube, which also has a download link to some high-res JPEGs. (not sure if I'm allowed to post the link per the forum rules, so I won't). I don't speak German, but from the Google auto-translate, I *think* it's a very positive review, except for video AF performance. The JPEGs are really impressive.
I'd instantly buy this lens, if not for the fact that I have a stellar copy of the Sony 35/1.4. So that makes the decision a little tougher. There's obviously no question that the Sigma's a better lens, more a question of whether I'm willing to carry around the extra weight relative to the extra image quality. Hoping that one of the local stores here ends up stocking the Sigma so I can do a direct comparison.
