Zeiss Loxia 85/2.4 vs Zeiss Batis 85/1.8 vs Sony FE 85/1.4 GM vs Sony SAL 85/1.4 ZA. Battle of 85mm lenses for Sony E Mount – Comparative Lens Review
Image Quality – sharpness
The verdict is simple here – all four tested lenses can render technically much better images that I can artistically follow. In other words, all four are among best portrait lenses that you can buy today.
There are some differences sure, I will try to comment on a few, but this will be rather for the purpose of the review itself, than for any practical purpose. At the end, if considering one of those lenses, you should be more focused on other aspects than image quality itself. All that in my humble opinion of course…
ISO 12333
Formal studio test can show some of the lens rendering tendencies. I made a 100% crops for easier comparison, but you can choose to see images in the original file size on my service Flickr album
One thing is immediately noticeable – Sony SAL Planar 85/1.4 ZA has significantly more pronounced chromatic aberration, especially wide open. At f/2.4 where Loxia starts though, this aberration correction dramatically improves and in most of the portrait applications in the field, it shouldn’t be a problem.
Apart of CA, Planar is actually very sharp from f/1.4, I would dare to say that it is slightly sharper than Sony FE 85/1.4 GM in the center of the frame. At f/2.4 in contrary, Loxia seems to be overall sharpest, closely followed by Batis. The differences are however so small than in practice it will matter much more on the particular technique, lighting condition, distance of the subject and its steadiness than on the absolute MTF numbers from the formal testing.
I included few more lenses for the reference, where Zeiss Otus 85/1.4 remain sharpest (but new Sigma Art 85/1.4 seems to beat it in that regard according to DxO).
On the other side, you should see how Loxia, pulls away from older lenses in the similar focal length.
For the specific purpose of the portrait lens, sharpness doesn’t necessarily have to be of the huge importance. However the combination of sharpness, high micro contrast and character of the bokeh, certainly creates specific look. In that regard, I am still amazed by the look of Otus 85/1.4 images wide open, even if the bokeh shows onion rings in the highlights, but I rarely use this lens for my work, where more commonly used apertures vary between f/2.8 and f/5.6. At those apertures, all tested lenses are super sharp, and I need to spend quite some time in retouching skin imperfections of my dear clients.
Another story is sharpness toward image borders. Because I usually want my models to separate from the background so that the viewer attention naturally fall on them (usually on model eyes), instead of expecting sharpness across the frame, I prefer more pronounced spherical aberration, that usually helps in creating bokeh with certain specific, painterly look. My most often used portrait lens is the old Zeiss Jena Biotar 75/1.5 which has exactly those characteristics.
This is main reason why I don’t really care about sharpness in the image corners at wide open aperture, for this type of lenses. Nevertheless all tested lenses show well corrected spherical aberration and surprisingly good performance even at the extreme corners of the image at wide open apertures. Loxia is probably winner in the corners (by very small edge) at comparable apertures.
At f/4 it is hard to tell the lenses apart from each other.
In the album bellow there is a scene with focus set at infinity. Aperture starts at f/2.8 and ends at f/16, where diffraction affect sharpness. For the images in the original size, please visit Flickr album
As I wrote at the beginning of this section, all four lenses are very sharp. Loxia is really great wide open for all purposes, but so are others when stopped to f/2.5 (2.8)
Thanks for all your hard work in doing this. Of these I have the Batis which I really enjoy and the Voightlander which, despite some flaws, is quite light and renders well. I also have a C/Y Zeiss 85mm 1.4 and the Helios 40-2 which is based on the Jena that you prefer. I am interested in the Loxia, which the budget may one day allow, as the Loxia 50mm I own is a personal favorite.
Hi Chris, you have lovely collection there. While Batis does everything very well, Loxia is certainly attractive on its own way. I’d love to own one myself.
Cheers,
Viktor
Thanks a lot, Viktor! This must have been a very hard comparison. I used the Batis and the GM. The Batis is sharper wide open as you mentioned in the review, but the bokeh is harsh at some situations (and great at others). Currently I’m keeping the GM until Sony releases a 135mm 1.8 for FE, because this is my favorite portrait focal length.
I think Sony marketing campaign overhyped the 85 GM. It’s kinda soft wide open, and gets to the level of sharpness I like at around F2. It is less than what I expected really, but the bokeh is better the Batis, that’s why I’m keeping it (for now).
Hi Yasser,
thank you for your comment. I tend to agree about Batis bokeh, but for the Sony FE, I think it is great lens in fact. As I said at the beginning of the review, all of those lenses are much ahead of my needs and competence, but Sony FE has very nice rendering of OOF areas and slightly lower contrast (in comparison to Zeiss), which makes it distinctive portrait choice. Batis however has faster AF, Planar is cheapest and sharp as hell and Loxia is smallest. Before you go with expected Sony 135/1.8 (shouldn’t take too long AFAIK), you might want to check new Batis announcement. I can’t say what it is until it is officially released, but since I had it for the test, I can say that it is exceptional lens in every regard. Give it a try if you can, when it comes. I promise you won’t regret 😉
You tested the new Batis 135 and you think it’s an exceptional lens in every regard? WOW
Thanks, Viktor for the Batis teaser 🙂 I think it will be announced tomorrow, so I’m looking forward to it.
That being said, the sample shots I saw so far showed a bit harsh bokeh, but you are one of the few lens reviewer I trust, so I will definitely give it a try. I already put my GM on sale because I really cannot stand the size and wight. I will continue to use the Apo sonnar with metabones until I can get that Batis 🙂
Victor, is that Sony 135/1,8 information based on just a guess or do you have some information that there is one coming up? I’m trying to decide if I should get the Sigma 135mm + adapter or hold off until there is a native sony lens. I don’t want to wait more than 6 months. Thanks
Hi Maciej,
let’s call it a rumor and threat it as so. Even when we know something, things can rapdidly change (firmware problems, production optimization, delivery prospect etc.) so just go ahead with what is recently available. I will certainly consider also Sony SAL 135/1.8 (if you are after super fast aperture), since it is very good lens that you can have for as low as 1000 USD (second-hand) and if/when Sony E become available, you can re-sell it with a small loss. With new Sigma, you might lost a bit more and I wasn’t impressed by its bokeh from the sample images that I have seen so far.
If you can live with f/2.8, Batis 135/2.8 is a superb lens.
Cheers,
Viktor
Thanks Viktor, much appreciated. By the way I am a big fan of your review style, it’s very comprehensive. Keep it up!
Thanks Maciej, we will try!

Hi Yasser, Batis 135/2.8 review is online now and you can check many sample images in VBL review here. As for the bokeh, it is neutral with well corrected aberrations – there is no sphero-chromatism (colored highlight outlines and no significant stroking of highlights either). Highlights are also free of artifacts such as onion rings and the only downside is pronounced mechanical vignetting causing cat eye highlights toward image edge. Bokeh is smooth and in combination with great sharpness and hogh micro contrast it delivers superb subject isolation.
Cheers,
Viktor
Thanks a lot, Viktor! I read the review, and it’s a good lens, but the price is crazy, given how similar it is to the Samyang.
If your GM is soft wide open, return it because that is NOT how this lens performance. I did not pay that amount of money for a soft lens…if it was, I would have sent it back. Mine is fantastic!
Hi Mark,
It’s not soft, I never said that, it is slightly softer in comparison to Planar ZA in the center, but IMHO it is deliberate design choice. In comparison to other two lenses (Batis and Loxia) it is a bit apples to oranges, since it is much faster lens. It is indeed great lens, enjoy yours!
The 85mm GM is just a beast!
🙂 I assume you have it. Congrats!
Another comparo tour de force, Viktor, thank you. 3D Kraft did an excellent early comparo of O85 and B85, and I concur with your views on these two. I shoot travel (street portraits and scapes) and favour slower, simple design lenses, so the L85 is a lay down misere for me. People miss that ‘found’ human subjects (esp. strangers, esp. women) react very differently depending on the ‘frontal area’ of (mainly) lens diameter.
MTF wise, L85 is Milvus85 level IQ at half weight/size and has better corners. Needs no distortion correction in post. It’s true Sonnar design (no asph) with CZ’s very good APD glass (hence the high weight for 7/7 manual lens). I feel very fortunate to have one. Typical Zeiss micro color/micro contrast and deadly infinity results at f5.6-f8 too. Feels bomb proof, ‘industrial art’. cheers.
I agree Philip, Loxia is little (relatively speaking) gem. I bet it will keep its value better than its electronic peers over time.
Thanks for the comment and support,
Viktor
Fantastic article Victor. Maybe the Loxia one day.
Thanks David, I wish you get one!
Very good comparison in deed, thanks Viktor! Nice to see the ZA 85 included in here, the first wow-lens I ever got. Great to see that it holds its own against the new designs (despite its flaws). I dont have it anymore as it was stolen from me and when I switched from A to E mount I got the batis and later the GM as well. It somehow still has its place in my heart, as the later two never really replaced it completely. It had this special something for me… Dont get me wrong, the later two are great (batis for traveling GM for serious work), but still, sometimes I miss the ZA rendering…or perhaps its just nostalgy 🙂
Thanks Jozef, It might be the lack of focus breathing what makes Planar ZA special. At the minimum focus distance, it is capable of creating larger highlight circles in comparison to GM at the same conditions, which makes subject standing out more/differently from the background. It is also very sharp (at least my copy), but it suffers from heavy CA. I like it to.
Cheers,
Viktor
The loxia is simply breathtaking! I could live with any of them, but give me the loxia!
Great lens for sure!
Hi Viktor and thank you for your objective reviews. In this article on the specifications page there’s a small typographic misplacement of filter diameters (should be Batis 67mm while Loxia is 52).
Again thanks for all you efforts.
Thank you Harout for your kind words and spotted fault. I will correct it asap.
Best review ever
