#403. Zeiss BATIS 25 on Sony A7rII. A brief review

By pascaljappy | Review

Sep 14

As with the Zeiss Milvus 1.4/85 before, I took the opportunity of a workshop in Schwäbisch Gmünd during the recent Zeiss press launch to borrow a Batis 25 lens and make a series of test shots in the available time and location. As many of you know and lament, this is a hard lens to get your hands on, so I hope these few lines will prove useful for those of you still sitting on the fence and comforting for those having hit the button and still waiting for delivery.


Wladstetter Bach in the sun – Sony A7rII & Zeiss Batis 25


This lens is light, very lightweight. Coming from a long session with a bulletproof Milvus 85 on the camera, switching to the Batis 25 felt like I’d forgotten to actually mount a lens. Scary, initially, but the lens feels very taut and solid with no rattle or shakes.

The design codes are inherited from the prestigious Otus range and suits the lighter brothers very well. The whole Zeiss offering is getting that new family look that brings a modern edge to a traditional build. Less steampunk,  more Apple. This to say the lens sports a very elegant body and, on an A7x camera, is something of a designer statement.


It’s not always black or white – Sony A7rII & Zeiss Batis 25

It goes just a little bit down hill, in use. At least for me.

Automatic focusing, on a wide-angle lens, and one that focuses as quickly as this one … why not? When traveling, it coud even be very useful. It’s true that AF imposes constraints on the glass weight and limits the designer in his optical optimisation. But since there is no shortage of quality in this Batis 25, I really can’t complain.

The lack of an aperture ring on the lens bothers me a bit more. Sure, you can set the camera to A mode and chose the aperture via a knob on the camera. It’s not intuitive after 4 dog-lives of doing otherwise, but you soon get use to it. What I really don’t like is not knowing what aperture I’m in. It’s part of my shooting process to choose the aperture as I approach the subject then reset the aperture to f/4 or f/5.6 (whatever is closest to the middle of the aperture range) when the photo is made. Just as I set the focus distance to infinity after a shot. Small things that mean you always know where you are and allow you to capture quick-moving subjects efficiently.

But, again, this is just me. As with all of Zeiss’ range today, the Batis was imagined and designed with a use case in mind and the intended user clearly has fewer white hair than me. Younger generations will likely feel more happy with the equally fast and efficient point & shoot & turn the knob approach.


Objective “test”

This house along the Waldstetter Bach will serve as test scene. The following 3 photographs are made at f/2, f/4 and f/8 respectively with no profile correction in LightRoom. Click them to download a full size jpeg.

At 100%, f/2 is visibly less sharp than f/4. However, the subjective quality of the image doesn’t degrade as you open up. All 3 photographs below look almost identical at web resolutions and would probably continue to do so in 16″ prints. No sponginess or smear is to be seen anywhere at wider aperture, which is great on a wide-angle. Chromatic aberration is superbly controlled straight from full aperture (look for tiny green fringes along the roof).

And this, well, fascinating scene, shows how well flare is controlled. The sun is just outside the field at top left.

DSC06073It seems to me the limits of its optical quality are reached very close up. This bee, on the edge of the frame, at full aperture and at closest focus is not quite as sharp at 100% as more distant subjects (as befits a landscape oriented lens). Still, minimum focusing distance is very useful.


Bee nice – Sony A7rII & Zeiss Batis 25


Colours appear very clean. Possibly not as subtle as Zeiss’ very best, but full of life. 3D is very convincing, hardly surprising for a good wide-angle,  but the Batis 25 manages to maintain this illusion of depth in the out of focus areas, which is never a given.

A much longer test period would be necessary to evaluate the lens more thoroughly. I hope this can happen soon. But so far, so good 🙂


Subjective Test

My personal criteria and tastes for lens quality place neutrality to the front of the scene.

For me, the ability to post-process files in very different ways is a requirement. It’s surprising how many good lenses have a distinct look to them that glows when PP goes with the grain and deteriorate badly when your mood requires something different. My beloved Leica-R lenses are examples of this.

The three photographs below were made within 15 minutes of one another in the same location. The fact they can be made to look so different is a testament to the neutrality of the little Batis. This lens would make a really wonderful travel photography companion.

Afternoon walk – Sony A7r & Zeiss Batis 25

Subjectively, I don’t think this lens has as much bite and pop as my Distagon 2/25 ZF.2. It is much better behaved, though, and comes with that elegant “satin” rendering that seems to be the recent norm at Zeiss.


In conclusion

It’s easy to see why Zeiss ran out of these sweeties so quickly. In this short period of ownership, there was nothing but good stuff to write about.

In truth, the new AF and build place a question mark over long-term reliability, since Zeiss is a newcomer in that field. But having seen its test procedures, and given its numerous technical partnerships, I wouldn’t lose sleep over this.

It would take much more time to get into the details and find possible faults but, from my short experience with the Batis 25 I’d give it the full thumbs up.

    It’s hard to stay happy with the best of the best after the flaws or limits begin to appear. Those with deep pockets have harder choices to make than us mere mortals. A boxful of languishing Zeiss primes is the worst luxury. My exquisitely sharp and lively 135/3.5 Super-Tak just revealed it won’t focus at infinity on an adapter. Oh well, just go buy another one on eBay…

    Just for giggles, I’d love to see a comparo of these new designs with the old garde.

    • pascaljappy says:

      Ah well, at least I strongly believe we mere mortals enjoy what we have more than those for whom money means nothing. I sold a lifelong collection of lenses to buy an OTUS 85 and savour every second with it. Now, I’d love to try the cine lenses, just for a few hours, but can’t think of anything that would make the OTUS feel less gorgeous.

      Sorry to hear about the adaptor trouble. That can be worrying and infuriating. My last experience with a metabones put my camera on its knees. A little traumatic, on the moment …
      85mm lenses and possibly 25s as well. Will let you know 🙂

    I loaded a comparison of three lenses in full res.:
    Zeiss Batis 2/25mm vs. Sony/Zeiss 4/16-35 vs. Sony/Zeiss 4/24-70
    you find it here in a special flickr album:
    judge yourself, but for me the 16-35 looks very good.

    • pascaljappy says:

      Thanks Dierk, that’s a very useful resource ! I’m also surprised at how well the 24-70 is doing. It’s not a zoom with a very good reputation, unlike the 70-200. The Batis has strong distortion in those photographs. I didn’t notice that in the field. There was some wavy distortion on the top of the roofs but nothing as pronounced as that. Weird.

  • Jens Kotlenga says:

    Once again: great work on your reviews of recent Zeiss offerings.
    At the launch event in Oberkochen, did you get a chance to find out more about the Batis range regarding design of the lenses and production? I’m sure you bloggers fired off some questions regarding the rumors that Tamron is actually being the “original Zeiss” design that Zeiss claims for the 1.8/85mm – what with there being a patent for a very similar lens by Tamron – and the lack of a flat denial of 3rd party involvement on the Zeiss lens blog.
    Any insight would be welcome.

    • pascaljappy says:

      Thanks Jens. We have no official news about that. Zeiss acknowledges that the vast majority of lenses are made by 3rd party companies, trusted partners (in Japan, mostly) that have been around for a long time. Only the most expensive cine lenses are made in Oberkochen. It seems there are warranties on the Batis range that are being honoured by Cosina, so my guess is that they are building that range. But I really have no certainty about any of this.

      Cheers, Pascal
