I didn't realize I'd miss having a standard portrait lens since I sold the Sigma 105 1.4 (utterly amazing). I will hold out either for a fast 105 or 85.We'll see a GM 85 with f/1.2 within a year or so - don't worry - it'll come and it'll be as good as the Gm 50 f/1.2 - just an outstanding lens 2nd to none.In the meantime have fun with the existing GM 85.It is already a very very nice lens with prefect out of focus blur and it's more than sharp enough. The number of situations where you'll need f/1.2 is limited. Though I have to admit in the situations where it works it's indispensable for my taste.Don't listen to the nay sayers that don't understand the usefulness of a fast prime.Fun fact - the Canon 85 f/1.2 L was so soft wide open that it was unusable for me. Rented it twice and never liked it. My GM 50 is just amazing in sharpness wide open - the Gm 85 f/1.2 will be surely similar in capabilities but it will be on the pricy side as all new lenses.Just educated guessing but I am pretty sure that we'll see a 100 MP camera body and some really nice lenses.I didn't read anyone questioning the usefulness of a fast prime. It is needing 1.2 vs 1.4 in 85mm, with the lens size, weight and cost increases because of 1.2, that people are questioning.This is similar to what we have with 35mm. Sigma 35 1.2 substantially larger and heavier than the Sigma 35 1.4 and Sony 1.4 GM.I am sure a new 85mm GM will be an awesome lens. Question is how much better it will be over current lenses besides aperture.As Sony users, we are spoiled with quality lens choices.+1Agree with that. It's all a question about how much blurry background one needs or wants, and how much weight, size and $$$ one is willing to spend to achieve that last little extra in blur. To me f1.8 in a 85mm lens is perfectly fine. Gives perfectly pleasing portraits. So I guess I am luckyThe choices we have in E-mount are astounding!agreed - in case the new GM 85 f/1.2 will follow the pedigree of the GM 50 vs the ZA 50 it will be similar in weight and size to the current GM 85.No need to worry - the intend use is not hiking.

You then interjected with the Z 200-600, something completely unrelated to the topic.If you haven't used the 85mm f/1.4, you'll find that it's very slow to focus. Heck the f/1.8 focuses qyite a bit faster. Does it need to be quick? For portraits, no, but for what I want to do with it, yes.Sounds like you need to stop shooting down and worrying about what others want.

Thread is about an 85mm f/1.2, the impetus of which was the announcement of the Z 85mm.i'll try to make things simple, since you are apparently having issues with the english language.nikon has nothing to do with what sony releases, as i pointed out with the nikon failure to release a z200-600 that they have had on their roadmap for three years or whatever it's been, and vice-versa.fyi, there isn't any z85/1.4; sony has it, nikon doesn't, it's entirely different scenarios.you keep claiming that sony has to do what nikon does = failure to understand that these companies have different marketing priorities and different lens lineups.You then interjected with the Z 200-600, something completely unrelated to the topic at hand in an attempt to defend Sony.wrong again, the irrelevance started with the absurd notion by the o.p. that just because nikon has an 85/1.2 on preorder, sony now has to do the same thing.that's a ridiculous notion, that you clearly don't understand.If you actually used the 85mm f/1.4, you'll find that it's very slow to focus.sony says it's 20fps on the a1, i think that they know more about it than you do.the 85/1.4, 90/2.8, 200-600, etc. all use ddssm focus motors... i own two of those lenses, they both work well for sports; certainly better than the slow stepper motors that nikon uses.i think that you don't shoot sports so you don't understand why focus motors matter.Does it need to be quick? For portraits, no, but for what I want to do with it, yes.oh, you didn't know that the z85/1.2 is going to have slow stepper motors in it? tell us again how sony has to do everything that nikon does.Don't know why you're upset over what OTHERS want -you just attacked me over what i want, lolpot calling the kettle black.

I know f1.2 is great, but Canon and Nikon are already delivering it. What Sony should be delivering, IMO, is rather fast f1.4 lenses, which are compact.I personally don't care about f1.2 vs f1.4, but size matters. I've tested the Canon 85f1.2 which made me drool, but it was so huge when I had it in hands that I figured I'd never bring it with me "just in case". But a small 85f1.4? I'd bring it with me anyday.The 50f1.2 GM was great, but hopefully, Sony has learned that f1.2 lenses are very niche, while f1.4 compact lenses are much more practical.

That would be a wish of mine.Unlike these ultra slow 24, 40 & 50 that honestly didn’t deserve the G tag.

From a marketing standpoint, I get it.Sony already has quality 1.8 lenses. 20, 35, 55, 85.With Sony, Tamron, Sigma, Samyang, we are spoiled with great lens choices at different price points. Off the top of my head, I cannot think of any glaring gaps or wishlist lenses for my uses.I like my Samyang 85 1.4, but autofocus is a weakpoint.  A new 85 GM interests me. The current Sigma is there too.

Probably would get a 35/1.8, and a 24/1.8. Right now I don't know if the 20/1.8 G is too wide for me, the 24/1.4 might be more than necessary and thus is a bit too expensive.

With the 50mm f1.4 GM due next week I hope Sony do an 85mm f1.4 GM II, 85mm f1.2 GM and 35mm f1.2 GM. Similarly from Sigma I hope they make a 50mm f1.2 Art DG DN and 85mm f1.2 DG DN for those that want f1.2 glass at a lower price 🙏

Sony doesn’t seem to be in any sort of hurry with these.However I think 85/1.2 will be released close up to A9iii release that seem more and more like it won’t happen this side of summer. I also doubt we see more FF lenses then the 20-70 and the rumoured 50/1.4 and 16-35ii before summer hit.

If Sony do ever release a f1.2 GM it will be at minimum £1800 if not more. So if both Sigma and Sony had a line of 35mm, 50mm and 85mm f1.2 primes the Sigma versions would be significantly cheaper. That would be of interest to many users.

The Sigma one is pretty amazing optically, the Sony one would no doubt match the optics and be lighter and a bit better flare resistance.The 100mm GM is fine as is and offers a different look, so I think Sony can sell both the 100 GM and 105 GM.Edit: I guess a DG DN version is also possible, paired with Sigma's new AF motors would be sweet.

A new 85/1.4GM II would also be great as the autofocus speed (with closed down aperture) is, let's put it mildly, not great. I would hope that the bokeh will be great with really nice round bokeh balls and no cat's eyes. For that the front lens has to be sufficiently big, but as long is the lens is, relatively, light, I would be fine with it.

I think it did fairly well on chromatic aberration not GM performance but really I have no complaints either.Astigmatism, distortion, Coma where not the best I seen in a wide, it also had some mechanical vignetting and onion ringing that I personally found a bit disappointing. Vignetting was about the same on all 3 I could see no real difference there. For me it is a lens that is going to divide the waters and mostly about what 1.2 dos. I know some like it for that and it’s rendering but I really also think they made some compromise not all will appreciate.Overall it’s a fine lens, but better optics then the APO and GM absolutely not, there absolutely no objective data to back that up. For me it’s a purpose built lens, so I’m not going to say it worse either as that would be unfair, as 1.2 is alway going to have issues with center sharpness compared to 1.4 and 1.8/2 lenses as it currently stands. We seen the same now on GM 1.2 vs 1.4 On the 50mm where 1.4 is obviously sharper at center.But 1.2 will always have its crowds, who will insist that it’s the best lens with the best optics largely because of what 1.2 lenses tend to do rendering wise, we see the same with the different 50 1.2. Who insist it’s the best although objectively there really no data to support such claims. But 1.2 just have its fans and I don’t bother having a lengthy debate yet again over this.I do like the new 20 from Sigma perhaps a tiny bit better then the Sony 1.8.
