We have two 35/1.2 on various Sony cameras and no problems at all, some wedding photographers we know, however, report issues. It is a bit weird.
It may be that, for whatever reason, not everyone is affected, or not everyone is aware of it, but Sigma wouldn't admit it if it wasn't a problem.
My body is an A7RIII and I have meanwhile also tried the A7RIII of a friend with the same result.
So if you don't have the problem you can be satisfied, but you will certainly understand that you cannot accept such (illegal) behaviour of their service department with a lens in this price range.
In fact, I have not been able to use the Sigma at f1.2 since the end of July 2020 and Sigma refuses to exchange or take back the lens. Sigma wrote, I should just wait until there is an update at some point. And when that is, I could check their homepage regularly.
After 2 months of waiting for a solution and non answers or unfriendly emails of Sigma, I will return the lens to the seller and if necessary file a lawsuit to get my money back.
So you should know that Sigma, if there should be a real problem, does not feel like fulfilling guarantee claims.
Sorry for off-topic, but I think that plays a role in the evaluation of new lenses when Sigma is obviously more interested in throwing new products on the market than fixing problems with a 1 year old premium product.
I'm very interested in this lens (the new 100mm) because I really like the focal length. I also had the 100mm macro on Canon and was very satisfied. Unfortunately, for the reasons mentioned, I can no longer buy a Sigma lens for the time being.

I know. As I said, others we know have problems, too. So we seem to be lucky. I mainly use the lens on the A9ii/A9. Sigma only referred to the A7rx in their announcement, but our friends use the A9, so it doesn't seem to be related to the A7rx alone.
My experience with Sigma was great until now, so I can't complain about their service, to the contrary. I am pretty sure they will provide a firmware update, too.

Following this lens with interest. I'm currently lacking anything above 85 and I've been considering selling my FE85/1.8 since I prefer Voigtländers and might get the CV75/1.5 instead. My main macro candidates have been the two apo-lanthars, but this might actually be the new preferred lens, if the af is good enough also when tracking moving subjects further away.
I really, really like that there's a physical Aperture ring and the build quality seems really nice. And the physical form factor seems really balanced with these Sony bodies.

Hmm that is indeed outrageous if they refuse to fix/exchange the lens for another copy. The question is whether it's a local service center decision or Sigma itself...
Sorry for the offtopic, but if that's how Sigma warranty service works globally and for all their lenses, then the 5-year warranty I have on mine is not worth much .

Arguably the Sigma "looks" less complex (you note complexity not limited to Sigma) than the Sony and CV 110, and I was able to get a good copy of the CV 110 on the first try. Arguably the Sigma is similar to the CV 125 (an older design) in terms of complexity. Watching the Sigma video posted in this thread, it seems like extra care was taking to keep ghosting (and I assume flare) under control.
Sony FE 90 G
15 elements in 11 groups
CV 110
14 elements in 12 groups
Sigma 105
12 elements in 7 groups
CV 125
11 elements in 9 groups
I haven't (as far as I know) had my CV 110 go out of whack, and I'm not sure how to evaluate whether something was underrepresented in the optimization.
The new Sigma is now 17 elements in 12 groups (spec per dpreview). To me this is crazy for a 100m non-Apo, non-IS Macro, considering the CV125 was at its time the highest considered APO design. On the other hand the focusing mechanism by moving a single lens block counters my argument of increased complexity on the mechanical side.
BTW, only Canon succeeded recently to reduce the complexity in their RF 70..200mm f2.8 from the latest EF version.

It looks like it will beat the FE 90/2.8 in axial CA control. That may not be enough for current Sony owners to make the switch but it's something to consider. The Sony is sharp and contrasty at center but how the corners compared to the new Sigma? I do not know but it's worth investigating, especially for those in the market for a macro lens.
To be clear, I skipped the Sony a few years ago because I was contemplating a huge slide scanning project. For that particular purpose the CA did not recommend it, I've seen somewhere on the net a comparison of Sony with vintage Nikkor and Zuiko for slide duplication purposes and the Sony wasn't the winner. The Sigma 70 was the better lens for that purpose, however I skipped it too since it would had little use beyond that project. And yes I am aware of the great APO Lanthar 110 however I didn't fancy manually focusing on thousands of slides.
Back to the Sony - beyond the specific purpose of slide scanning and repro use, I don't find any issues with it. If I were looking at flowers and bugs, the OIS would be more useful I think than less CA.

OIS isn't very helpful at all in the macro range. If you need stabilization for this type of work, IMO, you need a tripod for flowers and either a tripod for critters if they aren't moving very fast or a monopod if they are. Image stabilization just doesn't add much for such close distances. CA control, however, I have found to be a very important feature and I wouldn't get a macro without good CA control.

This Sigma release got me thinking what's the best (well the best all-rounder at least) macro choice for Sony now...
Does OIS gives significantly better results then IBIS alone in macro usage?

The more exact question is: does the OIS+IBIS on the Sony 90 work significantly better than IBIS on the Sigma 105? We don't know at this point, but as an educated guess, electronically controlled things like AF and stabilization have historically worked better on Sony lenses than third party ones.

You are correct, it looks like B&H has incorrect specs (I used their compare functionality for the 3 lenses that are still in production.) I'll put a warning on my post to reflect my mistake.
My post was genuine based on the incorrect info I was seeing.

Yes, I noticed that too in the video. It will be interesting to see how things pan out in regards to your concerns. It did take a second try for me to get an acceptable (in my eye) copy of the Sigma 14-24.

You're completely ignoring the fact that many public conservatories (chock-full of interesting plants) won't allow one to deploy a tripod. It's either OIS or flash there. Plus, with good light, at magnifications lesser than 0.25 a tripod is not that needed anyway.

My Sony FE 90 tested to be about "equal" for overall IQ compared to the Voigtlander 105 APO macro I had; and posted some of those results on the CV 105 APO thread. The main advantage of the Voigtlander was obviously the APO'ness, but even the 90 isn't too bad in that regard I love the colors, contrast, and bokeh I get from the FE 90 AF/MF clutch works great in the field. It is also 110g lighter than the new Sigma. I'm a big fan of the 14-24 and 24-70 Sigma Arts's, but this one doesn't do it for me. I don't see anything about the Sigma that would make me want it over the Sony 90. ...Show more →
As I said, my comment is based on Dustin's test and for the price, I wouldnt pick the Sony over the Sigma IF those results prove to be the norm but I wouldnt go out of my way to sell the Sony if I had it already either.
I was hoping for something else announced from Sigma as well :/

Yet another factor to consider (down the road) is the support and compatibility. There is a recent thread by freaklikeme on the sad Sigma 150mm macro in EOS mount.

I am not completely ignoring anything, but I am reporting on my experience and in my experience OIS, IBIS, or even the combo are not effective at high magnification--they add very little stabilization. As to whether public conservatories allow tripods I have never been told I can't use a tripod at such places. Maybe you go to different places than I do, but the key to taking pictures in such places is making sure you don't inconvenience any one else, and if I ever encountered a public garden that forbid tripods I would pick flash way over OIS, because flash could be useful if available light required too slow of shutter speed, whereas OIS would not help much. Further at magnifications less than .25 in good light not only is a tripod not needed but neither is OIS, so for those situations OIS is hardly an advantage. Now if someone uses a lens for other purposes than flowers and bugs, then I can see why they would want to have OIS. I am not saying it isn't a useful feature to have, but it isn't going to help much at high magnification whereas a tripod will be very useful.

The thing about 35mm f1.2 firmware update bug is that there seems to be some randomness to it as some people are not reporting any issues at all under the same conditions. In general, I'm happy with the way Sigma supports its DG DN lenses, so I hope this one is an exception, rather than the rule .
Sigma's CEO commented that AF was slower compared to non-macro lenses because an entire element group has to move back and forward and although not fast, it would be extremely accurate when shooting macro. I'm not sure if this is marketing talk but at least there was an explanation for this. He also said that tolerance would have to be even tighter for the optical design to work as designed.

Thanks, I'll guess we'll have to see how slow it really is in actual use.

I think I am the only person not in awe of the sony 90. It was an ok lens but not amazing to me and I actually hated the background rendering / bokeh. I've been looking to add back a macro with AF although was almost ready to go on the CV 65 or 110 because I love CV lenses.
I preordered this, it is right at that price point of ok if I dont like it I can sell it and only lose a little.

Good to know that 90mm f2.8 has some issues. I wasn't aware of it. Right now I use GF 120mm f4 (almost 90mm FF). Not sure anyone going to compare the Sigma FF glass with Fuji GF series.
