Lomography Daguerreotype Achromat Art Lens

This article was a very long time in the pipeline. For one reason or another I always postponed it even though I promised to Thomas (who kindly lend me this lens) to write my opinion about it. It might be that I don’t really write about gear which I don’t particularly in love with.

The controversy

I have a love/meh relationship with Lomography. There are products which I absolutely love such as the LomoGraflock 4×5 Instax back and some of their film stocks. In general I am really happy that they are there, form a community and bring more diverse options to photography.
But on the other hand I am not interested in funky plastic toy like gear like Holgas. I totally get why they appeal to a lot of people, it is just not my cup of tea. And also I am outright allergic to cringy marketing.

The Achromat lens while being made of glass and metal by its very nature leans into the lo-fi category to me especially with the creatively shaped aperture inserts.

As for why the cringy marketing nerve was pushed for me? The massive decorative text on the barrel of the lens:

Daguerreotype Achromat
by Chevalier
a Paris 1839

Achromat simply means that the lens is designed to focus two colors at the same point exactly.
While this is true that such a lens design was used on the official Daguerreotype cameras in 1839, and that lens was created by Charles Chevalier, this lens is a very far relative to the original one.

The original lens while had the same amount of lens elements and the placement of the aperture was similar was a very different beast. It had a much bigger image circle, the lens elements had different shapes and it was a lot slower. It was also nicknamed as the landscape lens.

In the end, I decided to give Lomography a break on this though as they clearly say that the lens is an Achromat inspired by the original design of Chevalier which is not wrong.

I had to reevaluate my feelings after I realized that the naming of the Lomo Petzval lens did not bother me at all. Could be that my judgment is tainted by the how much I actually like that lens….

So I had some baggage to unpack and process before I have even held the lens in my hands.
But let’s see how my opinion shifted after actually using the lens.

My setup

I used my mirrorless digital camera (Fujifilm XT2) with the Achromat. Initially I tested a simple adapter which allows mounting of Canon EOS mount lenses to my Fuji X camera. But because I wanted to experience as much of the image circle with all the lens character that comes with it, I decided to use my EOS to X focal length reducer aka speed-booster.

This setup allowed me to play with the lens very comfortably. Using a mirrorless digital camera means that I could stop down the lens while being able to still see a clear image in the viewfinder as the camera compensates for the darker lens by boosting the signal. Focus peaking and punch in focus was also really useful.
The speed-booster helped to combat the crop factor and made the lens a stop brighter while supposedly should not had made any change on the way the lens rendered.

The best setup would had been a native full frame camera with Live view + focus peaking and in body image stabilization. Of course any other setup would be fine including EOS film bodies, though the viewfinder can get really dark once stopped down to any usable aperture.

Image quality

The image quality of this lens is certainly a mixed bag. Wide open it is simply terrible, soft and full with all kinds of aberrations. There is no big surprise there, this is after all one of the simplest lens design imaginable.

What is quite interesting though is how much things improve by stopping down. Around f8 the images are kind of OK, but certainly usable with a touch of character.
It really is crazy how much can be achieved by such a primitive optical formula if moderate apertures are acceptable for the photographer.

Sharpness

Let’s not talk about it. From f11, it is usable. This is not a lens for critical high resolution use cases.

Flares

The lens is not particularly prone to flaring. Less glass-air surfaces means there are less opportunities for internal reflections. Still, it is possible to throw some rainbow flares into the mix. I am not sure if it has anything to do with the lens, the UV filter I used or perhaps the speedbooster played a role.

I like the soft gloomy effect here

Bokeh

An aspect which I like is the bokeh. The fewer glass elements also means that the background blur is really soft without onion rings, or any other madness produced by complex modern aspherical lenses. Especially in close focus scenarios the bokeh is really pleasing indeed.

I have not played too much with the different non spherical aperture inserts. I am sure they could be fun, but I was more focused on the “normal” image quality.

Conclusion

Without a doubt the Achromat is a special lens. It looks apart both from the distance and the images it produces are also recognizable. It is for sure a good conversation starter which can be very useful for street photography.

The lens is well built, no plastic involved and stopping down improves on the image quality dramatically which makes it usable as a normal lens. It is manual focus only, but on a mirrorless camera, nailing focus is not very hard.

Otherwise you can embrace the pictorial nature of the lens which is again something that stands out from the crowd.

Could be a painting


All in all, I think Lomography has achieved what they set out to do with this lens and I it has it’s audience. Am I part of this audience? Not really. While interesting, this lens is not something I would buy. In addition, the fact that I can borrow this lens from a friend any time I need it for a project also eases my urge to get one. I will probably try it again on film in the future.

It definitely raised my curiosity towards other Lomo lenses in the lineup such as the Petzval with it’s crazy swirly bokeh. Hopefully it will take less time to put together an article about that lens.

A second opinion

In order to get a more well rounded review, I have asked Thomas (the proud owner of the Achromat), to share some of his photos taken with this lens.

So far I only have the pictures and I know that he used a mid range film EOS body to take them. I may update the post with more details regarding film stock and maybe even with his thoughts about the lens.

I really like this portrait. Even though it is very soft, potentially even out of focus, it successfully captures an expression.

The funny highlights in the bokeh are not obvious upon first inspection, but they provide enough eye candy to move the viewers attention from the subject on a longer look. I think this gives a bit extra kick to this image. It is already a killer shot as it depicts a Cannonet camera.

These abstract photographs are part of a four seasons series. Though to me a bit too far gone, it is hard to argue that they are unique. I have to admit that as a series they kind of work. These ones were shot on Kodak Ektar 100 using the Aquarelle Plates f6.3.

And finally a psychedelic one. Not sure what is going on with the colors, but I can imagine that temperature control was deliberately sabotaged by Thomas during development for artistic effect. I would certainly consider this lens to produce cover art for goa trance albums.

You can find the work of Thomas here.

If I get more context or photos with this lens, I will update the article and I hope that you enjoyed this second set of pictures as much I did. If so, please drop a comment.

Meyer-Optik Görlitz Trioplan 100mm f/2.8

I have already written a few lines about this lens in my Exakta Varex IIa review where I have published some film shots taken with it. Recently I have purchased an adapter which allows me to attach any EXA mount lens to my Canon DSLR so it is about time to inspect a little deeper what is the Meyer Trioplan 100mm capable of.

The Cooke Triplet

The Meyer Trioplan is a classic triplet (it has three strong lens elements separated by sizable air spaces). It is eventually a modern version of the Cooke triplet which was developed by H. Dennis Taylor (1862 – 1943) in 1893.

The simplest design that is capable of correcting all of the seven Seidel aberrations over a wide field of view is the Cooke triplet. H. Dennis Taylor invented this in 1893, using the advances of Seidel’s theory. It is named after the optical company in York, England, for which Taylor worked at the time, Cooke and Sons (later to become Cooke, Troughton and Sims). The lens is described in two very interesting United States patents, Nos. 540,132 (1895) and 568,053 (1896). Taylor’s designs, despite their antiquity, are close to optimum for the aperture and field he intended, given the glass types available in his day. The triplet uses two of the principles of a good design. First, the Petzval sum is corrected by the use of spaced positive and negative lenses, as described in Chapter 9 on telephoto lenses. Secondly, it has approximate front-back symmetry about a central stop, to control the odd-order aberrations, coma, distortion, and transverse color.

Even though countless variants had been patented of the Triplet designs they cannot be considered as original inventions rather routine designs based on Taylors work.[1]

Fun facts

  • Taylor developed his own mathematical tools to design lenses and if we can believe him he never traced any rays. His method was to design and optimize the lens on paper until he reached the best possible solution and then he got the lens manufactured. Finally, changes were recommended based on the experiments on a testbench with the prototype.[1]
  • Cookie of York is still an existing company with slightly different profile and name Cooke Optics Limited.
  • Even though triplets are simple lenses it was difficult to manufacture them initially because the position of the lens elements has to be very precise. Therefore many manufacturers preferred to produce four element lenses instead.[1]
  • Despite that the Triplet design is strongly outdated today, it is still used in the case of many lower-end cameras.

Characteristics

The interestingness of the Meyer Optik Trioplan is the unusually large aperture (f/2.8) which is remarkable because triplets are usually moderate speed lenses for good reasons.
This relatively high maximum aperture comes with a price as the lens shows a wide range of aberrations when used in this setting. On the other hand, this makes the lens somewhat unique with an interesting footprint some might use for artistic purposes.
The out of focus areas  (bokeh) looks very interesting at f2.8, especially when highlights are involved in the background. The light circles (for examples traffic lights) are surrounded by light circles which makes the bokeh really special and as many say psychedelic. In addition, there is a heavy glow around the objects in the in-focus areas, most notably around highlights. This effect can be very dramatic or almost not notable depending on the conditions of the shoot. Last but not least the produced image is rather soft all around the frame in most cases wide open.

Many buy and uses this lens because of the way it behaves at widest aperture,  but we have to admit that this lens is not a bad performer at all if stopped down just a slight bit. At f/4 and below the lens produces sharp images without glow or distractive psychedelic bokeh. In fact, it has some properties which are very respectable. The lens produces a very low amount of purple fringing around high contrast areas even at modern standards. The lens is definitely sharp enough for most purposes an due to the almost perfectly round iris it produces wonderful creamy bokeh. Furthermore, due to the staples aperture ring, it can be appropriated by videographers as it allows smooth continuous aperture control.

How the Trioplan looks like

My Trioplan came as a part of a beautiful Exakta kit along with the original box and invoice.

The lens can be disassembled very easily almost without any tools. I wanted to unscrew the lens hood only but as a side effect, I have managed to remove an entire lens group. It is not that bad as it sounds because eventually, I could take advantage of the accident. I could clean up the dust from the inside of the lens and fortunately, the assembly went well and the lens performs just the way it did before.  Last but not least you can get a very intimate view of the wonderful circle shaped iris of the Trioplan.

My film shoots with this lens (with Exakta Varex IIa) can be seen here.

Wide open softness and glow can be beneficial when shooting portraits, although I admit isn’t fit all portraits.

Recommendation

Pros

  • Reasonably good image quality when stopped down
  • Very low chromatic aberration
  • Circular iris
  • Good bokeh when stopped down
  • The special character at maximum aperture (crazy bokeh)
  • Continuous aperture selection ring without stops/clicks
  • Good built quality
  •  Aged glue can’t be a problem between lens elements as the number of cemented elements is zero
  • Focusing is very smooth (on my instance)
  • Cheap

Cons

  • The outdated optical formula does not deliver cutting-edge performance
  • Very soft and loaded with aberrations at maximum aperture

The Meyer Optik Trioplan is a fun lens to use, it is out of the question. It is also a cheap lens so the investment won’t make your family mad on you.

I would recommend to those who like to experiment with old lenses hoping to achieve some unusual results due to the character of the vintage glass. On the other hand, it is not a toy so you can rely on it when you need good image quality, you just need to avoid f/2.8.

Videographers could also appreciate this lens due to the click-less aperture ring so they can change aperture very smoothly while filming.

But this lens is not for everyone of course if you are looking for top image quality or features like auto-focus than you should definitely look elsewhere.
