This is newly purchased from BH.
As a 2000 usd lens, I don't want any compromise.
Not sure if there is anything i can do to fix it, if not I will start a replacement process.

Seems pretty nit picky to me. Unless it’s effecting how the aperture is selected I would say that you’d be the only person to know it’s like that.

All the Sony aperture controls are like that. I have the ZA, three G's, and a GM all with vague detents that don't precisely align with markings. They feel even worse. If it bugs you you probably want to avoid Sony lenses. Sigma lenses have more precise detents and markings even on their least expensive lens, but Sigma also doesn't offer the ability to declick. At least Sony seems to do a decent job getting the optics aligned now.

I own the 1 G and 4 GM lenses with aperture rings and none of them are out of alignment like in the OP’s photo.
To the OP I suggest sending it back for another copy that is properly aligned.

Is it misaligned at every aperture or just at the "Auto" position? If the latter, maybe it is not an alignment problem but an engraving problem.

I checked my own lenses- the detent on my 70-200mm gm2 is"off" a few mm, as are a few others.
I could care less.
If the lens functions properly this is in my opinion a non issue.
A $2000 lens, or a $100000 car will have issues if you look for them.
Go shoot, make art. Worry about the big stuff.

I agree with posters that say "A" doesn't need to be exactly aligned mark-to-mark. If the apertures don't align, that is a big problem for me, as I usually shoot with manually set aperture priority.
It is too bad the quality control/engineering isn't a little more precise for such an expensive piece of equipment.

I own 5 GM lenses and this is the only one that has such obvious misalignment. All other gm lens have a much more acceptable misalignment.

If it works I wouldn't bother exchanging it. Never really thought to check the alignment and I don't shoot in auto-aperture in any event

the detent marker is off by maybe a third of the width of the line?
did you test it for a tilted element or decentering?

I just checked my 3 GM lenses with this type of aperture ring.
70-200 f/2.8 GM II
50 f/1.2 GM
35 f/1.4 GM
None are dead nuts perfect. All are about the same, at about 1/2 as misaligned as what is shown in your picture. That basically keeps the smaller line inside the wider line buy not perfectly centered. They all function perfectly, so all are fine for me.
I hope that information is helpful for you in making your decision.

I just checked the same three lenses. The 35 and 50 are 1/2 misaligned and the 70-200 is nearly perfect. My Sigma lenses are all perfectly aligned.
I’m really happy to see that there is someone more ‘anal retentive’ than I am.

Send it back for a better aligned one. Resale value will be less with an obvious defect.

Tough call. I understand you want it to be perfect, and it should. On the other hand if it's perfect where it counts, centered, sharp and accurate focus I wouldn't want to send it back for an inferior copy, that may also have a misaligned ring.

Frankly, I didn’t pay any attention to the aperture ring alignment of my lenses until this thread. I just checked all my GM lenses and they all are okay; some are perfectly aligned and some are not 100% but good enough for me to even notice that before.
To the OP, I don’t know whether you use the aperture ring to change your aperture or not but if NOT set on “A”, is the set aperture off as noticeable as on “A” or is it off but not as noticeable as on “A”? Just curious…

People here are sometimes criticized for sending back a decentered lens. So a lens that has an optical flaw...
This tiny misalignment of your aperture ring does nothing to the optical quality.
If it doesn't have any optical flaws I would absolutely keep it. I wouldn't be this nitpicky.
But it's your money in the end...

That's the most nit picky concern ever ^^
A 2000$ lens seems expensive for a lot of photographers, but a GM lens, even at this price, remains a consumer lens, it's not a 15000$ cinema lens and there will be copy to copy variation. In your case, this copy to copy variation is about something purely cosmetical.
So if everything else is perfect (like fotografur said : centered, sharp, accurate focus), you should keep it and don't come back to the lottery for such a silly thing...
But hey, after all, it's your money, if you want to gamble it again, no worries. But if you show us this, it tells me that you're expecting a few comments about it. Mine is this : this concern is silly and you should keep your lens ^^

Seriously, I thing that at worst there will be 1 photographer on 500 that will be concerned by that. It will have zero effect on resale value.

This is a pretty funny thread. Gold-plated problems to be sure.
But to the OP: does it matter? Not at all. Should you exchange it? Probably, if it's going to bug you every time you use the lens. Though it is a gamble, you may get another one that's the same or worse.
