Review: Zeiss Batis 18mm 2.8

Introduction

Sony A7s with Zeiss 18mm 2.8 E Batis
Sony A7s with Zeiss 18mm 2.8 E Batis

The Zeiss Batis 18mm 2.8 is the latest addition to Zeiss’ line up of modern autofocus lenses and also the widest AF prime lens to date for Sony E-Mount. As many people (include me here) are now engaged in landscape astrophotography I am especially interested how the new Batis fares in this regard.

Specifications / Version History

This is the third lens of the Batis line up (the former two being the 25mm 2.0 and the 85mm 1.8) and to my knowledge the first 18mm lens by Zeiss with a maximum aperture of 2.8 (there has already been a 18mm 3.5 for (D)SLRs and a 18mm 4.0 for rangefinder cameras, though). According to Zeiss this lens has quite the complex optical design, as only two of the eleven elements are “normal” glass and the others are either aspherical, made from special glass, or both. It also has a floating elements design so I expect very good performance at close distances.

The Zeiss Batis 18mm 2.8 has the following specifications:

    • Diameter: 100 mm (with lens hood)
    • Field of view: 99° (diagonally)
    • Length:  80 mm
    • Weight: 330g
    • Filter Diameter: 77 mm
    • Number of Aperture Blades: 9 (rounded)
    • Elements/Groups: 11/10
    • Close Focusing Distance: 0.25 m
    • Maximum Magnification: 1:9.5
    • Mount: Sony-E

You may also have a look at Zeiss’ official page.

The availability is very limited right now, there are some on ebay.com (affiliate link) but mostly way above the MSRP, which is 1500$/1500€. The lens is now also available on amazon.de (affiliate link).

Disclosure

The Batis 18mm 2.8 E was kindly provided free of charge by Zeiss Germany for reviewing purpose for a duration of 4 weeks.

Handling / Build Quality

Zeiss Batis 18mm 2.8 and Voigtlander 15mm 4.5 SWH E

The Zeiss Batis 18mm 2.8 is a quite big (epsecially with the lens hood in position) albeit rather light lens. In the picture above I included the Voigtlander 15mm 4.5 E for a size comparison, which is significantly smaller but only 30g lighter.
The housing is made from metal (as it feels very similar to the A7s and is quite light I suspect the use of magnesium alloy) and dust and weatherproof according to Zeiss, but also attracts fingerprints quite easily.
The fly-by-wire focusing ring is rubberized and – as most FE-lenses – has a non linear coupling to the internal focus motor, which means turning the ring fast will result in greater movements than turning it slowly. I am not so fond of this and would prefer a linear coupling. The focusing ring also easily collects dust and dirt.
The rubber gasket is a little thinner than that on the Loxia 35mm 2.0.
The lens hood is made from plastic (one piece) and can also be mounted reversed for storing.
I rarely use autofocus for my landscape work and the A7s does not offer phase detect focusing as well, so I am certainly no expert in this regard, but during my brief testing of this feature the focusing was quite snappy and accurate.

OLED distance scale

Zeiss 18mm 2.8 E Batis (OLED Display)

As well as the former Batis lenses also the 18 mm is equipped with a digital distance scale. There are three settings: always on, always off and only on when in MF or DMF mode, the last one being the standard setting. The lens can also be set to show either feet or meters. Alongside the focusing distance there are also information on the closest and farthest distances with acceptable sharpness. In the picture above a focusing distance of 1.2 m is set and the area of acceaptable sharpness ranges from 1.2-0.26 = 0.94 m to 1.2+0.46 = 1.66 m.
I was very curious to find out how this works out in the field but after having used the lens for quite some time now I am a little disappointed because the lens pretends to show you exact values but simply doesn’t in real use.

To show you what I mean I have prepared a small example here:


I have neither moved the camera nor the focus-target but only changed the focus setting. In the “before” shot the correct focus setting was chosen. The distance scale on the camera says 0.3 m and the display on the lens says 0.3 m +0.01 -0.00 (the target is a measured 0.25 m away from the camera sensor).
For the “after” shot I turned the focusing ring a bit towards infinity (as can be seen by the bar on the camera display), the target is clearly out of focus now but the camera display still shows a focusing distance of 0.3 m and the display on the lens says 0.3 m +0.01 -0.01.
What is giving me quite a headache here is this: I have clearly and substantially changed the focusing distance but the values on the displays simply don’t show me that.
The situation isn’t that much better near infinity. The correct setting for infinity is at the turning point between XX.X m and infinity but the focusing ring can still be turned way farther and you are focusing behind infinity then, meaning nothing is in focus at all. Still the display on the lens will tell you infinity is sharp, which is not the case when having focused behind infinity, not even at f/11.

To me this matters, especially for astrophotography, but it may be no issue at all for you, as in case you solely rely on autofocus, you probably won’t even notice this.

Vignetting and colorcast

zeiss batis 18mm 2.8 E distagon sony e mount a7 a7r a7rii a7s vignette vignetting

Wide open there is some visible vignetting in the extreme corners which according to my measurements is around 2.6 EV and stopped down to f/4.0 around 1.9 EV. Zeiss’ data sheet shows only the values after the internal corrections which leads to only 1.4 EV wide open and around 0.8 EV by f/5.6. There is no Lightroom profile yet and color cast is unsuprisingly not an issue.

Sharpness

infinity

Sharpness across frame is very very good right from the maximum aperture. On the 12mp sensor I can see slightly reduced contrast in the extreme corners wide open, but otherwise simply excellent performance here. There is also no visible field curvature.
One thing to notice: in the compilation above I increased the exposure on the corner crops to make them comparable in terms of sharpness.

The centering quality of the review sample is very good, but I have to mention that another copy which Jannik from our team bought was visibly decentered.

close focus

Sharpness and contrast are unsuprisingly very good at close focus distances, even wide open. I already expected this because of the floating elements design. There is no softness and loss of contrast at closer distances seen in many of our reviews of older lenses.

Flare resistance

With the sun near the border or the corner of the frame it is possible to catch a rather unobstrusive red ghost and a little more obstrusive sickle shaped green ghost. The contrast seems to be not affected at all and stays on a very high level.
With the sun outside the frame the performance is excellent even without the lens hood.

Coma

coma correction batis 18mm 2.8 e review zeiss distagon sony e-mount
According to Zeiss one of the main applications of this lens is astrophotography, so I was very curious about the coma performance, which is indeed very good to say the least. Wide open even the extreme corners only show a negligible amount of coma but things get very interesting when comparing the Batis to my two main astro lenses (see my corresponding astro-landscape flickr album), the Nikon AF-S 14-24mm 2.8G and the Nikon AF-S 20mm 1.8G:

coma comparison batis 18mm 2.8
Nikon AF-S 20mm 1.8G – Zeiss Batis 18mm 2.8 E – Nikon AF-S 14-24mm 2.8G

In this comparison the Batis 18mm 2.8 E is clearly the best showing the least coma. I will soon try taking some shots of the milky way with this lens and adding them to the samples section.

coma correction batis 18mm 2.8 e review zeiss distagon sony e-mount comparison nikon 14-24mm 2.8G 20mm 1.8g af-s

Both Nikon lenses were adapted using the metabones adapter. My finding is that even this expensive adapter does not have the same exact flange distance as a native Nikon camera which can have a negative influence on the optical qualities, especially on lenses with floating elements design (which is the case with the 20mm 1.8G). Nevertheless I long ago made a comparison between the A7s with the metabones adapter and the Nikon D800 and in terms of coma I didn’t notice a visible difference with the 20mm 1.8G (corner sharpness wide open is better on the D800 though).

Use for astrophotography

This lens is advertised by Zeiss as a lens well suited for astrophotography and after having tested coma and vignetting I also had high hopes for it. Luckily I had the opportunity to shoot the milkyway under quite good conditions and the lens proved to be an excellent performer here. Stars are a little more forgiving to coma than cityscapes and I couldn’t find any traces of coma when shooting them at all. This is neither the widest (see Nikon 14-24mm 2.8G) nor the fastest (see Nikon 20mm 1.8G) lens for astrophotography but the sum of it’s parts makes it one of the best choices for astrophotography available to date, not just for E-mount but in general.

Distortion

Distorion characteristics of Zeiss Batis 18mm 2.8

There is some barrel distortion (mustache  style) which can also be clearly visible in architectural shots (see full resolution example below). This will be corrected in newer firmware versions (I am still running 2.0) and to my experience this lens will probably be included with the next Lightroom update as well.

Bokeh

With the 18mm focal length and a maximum aperture of f/2.8 you have to be close to your subject to throw the background visibly out of focus. The bokeh is quite nice without harsh outlinings but the bokeh balls can show an onion ring structure due to the many aspherical elements, as can be seen in this 100% crop:

Take a look at the following example to see what the bokeh looks like with the subject farther away:

Sunstars

You probably know by now I prefer sunstars produced by straight aperture blades but putting this aside sunstars produced by the Batis 18mm stopped down are well defined and quite nice.

Chromatic aberrations

Only some slight traces of green and magenta outlining can be found, pretty good performance here.

lateral

There is an embedded profile when using Lightroom for correcting the lateral CA which cannot be turned off. So to show you what it looks like without the correction, I took some shots without electronic contact between lens and camera.

As there are only minor CA this is a very good performance for an ultra wide anlge lens. The remaining CA can easily be corrected in post, as can be seen above.

Alternatives

Zeiss Loxia Distagon T* 21mm 2.8:
We got asked a lot about this comparsion – so I will try to go a little bit into detail here – but nitpicking between the optical qualities of these two lenses is pretty much pointless as they are both excellent performers in almost every regard. Nevertheless, I think the Batis’ coma correction is a little better while the Loxia has better flare resistance and nicer sunstars, but what should really drive your decision here are the focal length and handling differences.
A horizontal field of view of 90° (18mm) versus 81° (21mm) is quite a meaningful difference and here it mostly comes down to your preferences and the other lenses in your kit. You may get by with the 18mm being your widest lens and I could think of it nicely complementing an AF-kit for landscaping/archtitecture already consisting of the Sony 28mm 2.0 and Sony/Zeiss 55mm 1.8.
What really matters are the handling differences: the Batis is a designated AF-lens and pretty much meant to be used that way (I am not really fond of the fly by wire focusing ring and the OLED distance scale for manual focusing) while the Loxia is an all manual lens (when properly calibrated with hard infinity stop), which is also significantly smaller.
There is no simple “lens x is better than lens y” here, actually, there rarely ever is. Sorry. 

Nikon AF-S 20mm 1.8G:
You are of course loosing AF, Exif-data and 2mm but you also gain 4/3rds of a stop maximum aperture and more subject isolation. But the 20mm 1.8G also has higher vignetting, especially at infinity, and worse coma, so as of today, the Batis 18mm 2.8 would be my choice for astrophotography among lenses with a focal length of 18 to 21mm.

Sony/Zeiss FE 16-35mm 4.0 ZA:
This is your widest option with AF and OSS and of course more flexible in terms of focal lengths. In case you don’t need the faster maximum aperture or the superior image quality of the Batis this may be a good choice for you.

Older manual SLR lenses:
There are many legacy 20mm and even some 18mm and 19mm lenses availabe. Some are quite cheap on the used market (Minolta MD 20mm 2.8 or Canon FD 20mm 2.8) while others are unbelievably expensive (Leica-R 19mm 2.8). You might start taking a look at our comparison between the Minolta and Canon 20mm 2.8. In case you are running on a tight budget this is where you should take a look.

Conclusion

good

  • coma correction
  • very good sharpness and contrast
    already at maximum aperture
    across the whole frame at all distances
  • sunstars
  • CA correction
average

  • vignetting
  • distortion
  • flare resistance
not good

  • price
  • manual focus experience
    (in case you intend to use manual focus with this lens)

In case you took a look at the table above you probably know by now this is a very good lens with no real flaws.  The optics are great (at all distances and aperture values), the build quality ins’t bad either and the coma correction is really outstanding. Because of the last point I was also really tempted to buy this lens but I didn’t.

While the lens is really lightweight it is also quite big, especially with the lens hood, and I am not a fan of fly-by-wire focusing and the OLED distance scale.

Someone at Zeiss knew people would have different opinions on how the ideal lens feels and operates like and decided to settle for two different lines: Batis (lightweight but rather big, modern OLED display, AF, fly-by-wire-focusing, 9 rounded aperture blades) and Loxia (a little more solid (= heavier), all manual, smaller size, 10 straight aperture blades). In my opinion this was a really smart move.

I am more of a Loxia person. For my landscape work I mostly use manual focus and I highly value the smaller size, the smaller filter diameter and the 10-bladed aperture. But this does not mean the Batis 18mm 2.8 is a bad lens, it is actually a damn good one.

So, who is this lens for? Anyone, who looks for a very good, native ultra wide angle E-mount lens with AF, nice build quality and very good optical properties or simply one of the best lenses for landscape astro photography available to date. Of course this is no cheap lens and compared to the 16-35mm 4.0 you give up quite a bit of flexibility, so you better be sure this is the right focal length for you before buying one. Apart from this I have no reservations recommending this lens.

      1. I can absolutely understand this and will talk to Jannik – who owns and reviewed the Loxia 21mm 2.8 – about this and will certainly give you our thoughts on this.

        Bastian

  1. While I generally very much appreciate your work here at phillipreeve.net, I do not really understand why to test a presumably highly resolving lens on today’s least demanding 12 MP body. I mean, we all have our (mostly SLR) history, which is full of such cases. In my case it’s Nikon, where almost all (full frame) lenses perform well on the good old 12 MP D700, but take a D800 class camera and you will see that the pool of useful lenses is shrinking rapidly – I could tell a painful story here. In the Sony case: while I perfectly understand that an A7s(II) may have it’s merits, I would at least prefer 24 MP to challenge a lens.

    1. For resolution(sharpness) test I agree with you. The other tests (bokeh, sunstar, vignetting, ect.) should not be affected by the MP number.

    2. Thank you for your feedback!
      I personally think sharpness is heavily overrated and there are quite some people out there (lensrentals and dxomark to just name two) with expensive equipment to measure it way more exact than I could ever do (and they probably will do that in the near future).

      Finding reviews that are about the photos and not about the pixels on the other hand has become quite difficult but this is exactly what I want to provide:
      A review from a user’s standpoint and not from a technician or an optics engineer.
      So I put my efforts into providing useful sample images as well as information on handling, bokeh, sunstars and coma which are things the more technical reviewers often don’t cover and are also mostly not affected by the megapixel count.

      Apart from this I also see this as a lens for astrophotography and the A7s(II) is challengened by no other camera in this category so far.

      But I of course do understand the importance of the sharpness measurements for some of you and I will try to get hand on an A7rII and repeat the sharpness test as the difference between 12mp and 24mp is not nearly as meaningful as it sounds.

      Bastian

      1. Zeiss does the same thing on their site. On all photos except the one that should display resolving power of lens they use a7rii but on only true landscape they use a 7s… Why???

        1. Dear Jerre,

          of course getting hands on an A7rII should be less of an issue for Zeiss (in comparison to me at least),
          but they also lend the lenses to some real photographers for these images.

          As someone who sells architecture and landscape photos from time to time I can say customers mostly don’t care about the pixels.
          I can sell a 36mp D800 photo or a 12mp A7s photo, no one cares for or even sees the difference. Most of these images are printed in magazines or used for presentations or on websites, not printed on house walls.
          When shooting weddings I usually upload all the photos with 2000px (long side) in my dropbox to get them as fast as possible to the customer and always say to contact me when in need for higher resolution shots.
          Never ever happened.
          Most stock agencies’ (considering the ones I worked with) biggest upload size is 3000px (long side).

          I always welcome more pixels, all else equal, but rarely is all else equal.
          So I can understand, not every landscape or architecture photographer is using a 36mp+ camera.

          Bastian

  2. Hi Bastian,

    Does the focus (in AF or MF) reset on the Batis 18 when you power off the camera and power back on? If so, this might be a problem when shooting trails and battery needs to be replaced or you turn off the camera to conserve battery.

    Is infinity focus easy to achieve by looking at the OLED display?

    Great review as always. I have not seen a better comparison of coma. I am wondering if you had a chance to compare night sky pictures taken with Batis 18 and Samyang lenses.

    Thanks,
    Rajesh

    1. Dear Rajesh,

      first let me thank you for your feedback!

      Fortunately the focus setting does not change when turning the camera off and on.
      Just looking at the OLED screen may not be sufficient, but I found Infinity is best at the turning point between the infinity symbol and something like 20-200m.

      Right now Samyang only offers a 14mm 2.8 and a 24mm 1.4 (and a 21mm 1.4 for APS-C only), I think their focal lenghts are too different for a useful comparison.

      Bastian

  3. Dear Bastian,
    Thank you greatly for the detailed review. Exactly all the categories I would like to know. For one thing however, I’m not fully convinced by the coma comparison. Shots with Nikon lenses seem to be more over-exposed, with more highlight blown out and might thus cause more coma. Are these pictures done on one night using same exposure?

    1. Dear George
      same night, same exposure, different WB and of course different vignetting characteristics (which is probably the reason for the differences here.
      Bastian

  4. Dear Bastian,
    I am confused with how to set infinity focus.
    I received today my batis 18mm, and as i am an astro/landscape photographer set infinity focus is really important to me.
    I saw on oled that when we see infinity mark first time we can continue turn focus wheel and oled continue to show infinity mark. So where is really the infinity focus ?
    Normaly in other lens this also happen but we have a small mark above infinity mark to set with percision infinity focus.
    You said “Just looking at the OLED screen may not be sufficient, but I found Infinity is best at the turning point between the infinity symbol and something like 20-200m.”
    This not look loje to be really precise…can you explain a litle more?
    Thanks in advance!!! Excelent review.

    1. Dear Paulo,
      with my lens the turning point where you see the infinity mark for the first time was the right spot for good infinity focus and sufficiently precise.
      If this is not the case with your lens please share your further experiences here!

      I don’t really like using fly-by-wire lenses like these for astrophotography and also sent Zeiss my feedback regarding this.
      Bastian

  5. Can you compare the Nikon 20/1.8 to the 18/2.8 a little more? The Nikon is smaller and less expensive, but how different do you find corner-to-corner sharpness and micro-contrast between the two?

  6. Dear Brian,
    regarding micro contrast the Zeiss may be a little bit better but not by much. This is more like splitting hairs here.
    The Loxia lenses – at least to my knowledge – are more optimized for contrast and I can absolutely say that for the 21mm and the 35mm.

    The corner-to-corner sharpness highly depends on the adapter you are using.
    With my D800 (36mp) corner sharpness of the 20mm 1.8G ist at least good wide open, on the A7s (12mp) with the metabones adapter I had to stop down to f/2.8 for the same level of sharpness.
    I have not yet found the perfect adapter and lenses with floating elements design (like the 20mm 1.8G) suffer from incorrect flange distance.

    The safe bet would definetly be the 18mm 2.8 Batis here.

    In case you have any further questions dont hesitate to ask!

    Bastian

  7. Thanks for the great review, giving a very meaningful user perspective!

    Any chance of a Voigtlander 15mm (for Sony FE mount) comparison when it arrives? I also prefer a smaller lens if it has similar quality.

    Regards

    Richard

  8. Is it Milaneo and the Libary in Stuttgart? I was leave in Stuttgart and i leave in Böblingen. Nice to now a Photo expert in the near. Thank you for the Information. I would like to buy the lens for my A7R2.

  9. Sony admit in the manual that the distance and DOF numbers on the OLED screen are not accurate.Maybe it will be improved in a future FW update.

  10. Thanks for this review but almost regret to have gone for the Loxia 21mm…
    Would have preferred wider, 18mm is nice, but maybe there will be a Loxia 14mm somewhere in the future.
    But when I look at this review I must say that I’m hesitating again about buying the Nikon 14-24mm f2.8.
    Weight and a number of lenses is always a problem when traveling. Must say that I don’t like to change lenses to often (changing filters, danger of dropping,..)
    For the moment I’m using the A7r2, A7s plus as wide angles for day-landscaping the Sony 16-35mmF4 + Loxia 21mm and for astrophotography the Samyang 14mm f2.8 + sometimes the Samyang 24mm and/or 35mm F1.4, recently also the Loxia.
    Would prefer a lens like the Nikon 14-24mmF2.8 but I’m hesitating because I don’t know how it performs on the A7R2 (would not sell the Loxia but definitely the others).
    You seem to mention that the Nikon 14-24 is performing as good on the A7 series as on the D800.
    Would be nice to see a review of this lens in combination with the A7 series, A7r2 if possible.
    Until now, I didn’t find any review of this combo (A7 + Nikon) but could you, or someone else, confirm that the IQ is no issue.

    Friendly greetings.

  11. Thanks, Bastian, and to Philip, for this very thorough review. I’m shooting the Sony Zeiss Distagon 35 1.4 and absolutely love the lens… though I’m primarily shooting portraits these days with the Batis 85 1.8, which I’m very very happy with and not regretful for not further (italics) waiting for the Sony 85 1.4 as I frankly find the Batis bokeh charming and full of character… I also find the Distagon does fantastic portrait/environmental captures! Sharp, clear, lovely.

    At any rate, I’ll often want something wider when out shooting nature – the Batis 24 or Loxia 21 or now the Batis 18. These reviews help with my thinking. I downloaded the library shot and the evening lake/town photographs. Goodness, what a great lens! Peace, thanks again, and happy shooting. Scott

  12. This lens looked to be a perfect solution for aerial work with the digital focus distance. As most modern lenses don’t have distance scales it can be a real pain as the cameras are mounted to the aircraft and impossible to see the display. Seems you had poor luck with the distance display. Can it be calibrated? Nothing worse than flying for hours and ending up with soft images.

    1. 18mm would be too wide and f/2.8 could be too slow for general purpose work in my opinion.
      I’d prefer the Batis 25mm, it’s real focal length is 23mm.

  13. Hi Bastian. Thanks for such a detailed review! I just purchased the Zeiss Batis 18mm. At first, I was really happy with the overall sharpness of this lens on landscape shots vs my Sony 16-35. The corner sharpness is so much better than the 16-35. With that being said, I took the Batis out for some Milky Way shots last night and was really disappointed with the results on both my A7rii and A7s. I was getting star trailing with 13sec exposures. I switched to 10sec and still had the same results. Tried putting the lens on my A7s and still same issues. I refocused a number of times without any luck. Just for kicks, I put my Sony 16-35 on and did the same tests with the same settings. It produced perfectly rounded sharp stars with no trailing. I’m really disappointed as the Batis 18mm was supposed to be my go to lens for Astro and was to replace my Sony 16-35. Any suggestions or ideas would be very much appreciated!

    1. Can you pleaes upload a shot taken with the Batis and with the 16-35mm 4.0 from the same position showing the differences?
      I can’t give any advise without having seen the pictures.

    2. Are you sure you didn’t have the 16-35 set at 16mm?

      Trailing is a function of exposure time and focal length; not optical qualities of the lens (except indirectly as with a slower lens needing longer exposure)

      A wider lens will produce less trailing for a given exposure time than a longer one: so if the exposure times were the same, you should expect more trailing on the B18 than the 16-35 set at 16.

  14. Innanzitutto grazie per questa approfondita e veritiera recensione! Io posseggo una sony 7s2 ed ho da poco acquistato lo zeiss 18mm 2.8, credo sia fantastico come nitidezza e velocità autofocus, ma a volte amo fotografare in manuale focus e con questo obiettivo non riesco a farlo facilmente perché non ce un tasto nell’obiettivo. Come faccio a passare in manuale focus ? mi puoi aiutare? grazie

  15. What was the result of your conversation with Trevor, August 27, 2016vsbout coma. Did he ever send the pictures for comparison? I am going to Iceland to see the aurora borealis and was considering rending this lens. Any thoughts or recommendations would get greatly appreciated.

  17. You say there’s no field curvature and that’s right at infinity; but my copy does have a bit at shorter distances ( which might explain why some imatest reviews complain about the corners which seem fine to me)

      1. It’s relatively slight, but a metre or so if you focus centrally, the optimum focus is a little behind the nominal plane of focus at the periphery. Enough that if you are picky you might want to bear it in mind. Not enough to worry about (and *much* less than the opposite tendency in the old f3.5 ZF). You might want to check, though! Unlikely to be sample variation, but you never know….It’s only field tests that tell me this; I haven’t mirror aligned a chart and focussed on the centre and edges separately..

  18. Voigtlander 15mm or Batis 18mm?

    Astro, indoor, landscape, unusual angles, general use. I’m leaning to the Batis simply for lower light performance. I dont like soft corners much either.

      1. What about the laowa 12mm? , i prefer the wider angle and lower 2.8 compared to voigtlander, but need to know if the consistency/quality is there. I wasnt impressed at all with the quality /control of the Samyung/Rokinon 14mm, it lost image quality over time on the corners severely. (With the 12mm one can also just crop down to 15/18mm if the corners are a little soft, compared to the Batis 18mm).

        1. I only tried the prototype of the Laowa 12mm 2.8 so far,
          it is a fine lens and much better made than the Samyang 14mm 2.8 (MF DSLR version),
          but it is also much bigger compared to either Batis 18 oder Voigtlander 15.
