Carl Zeiss Jena Flektogon 35mm 2.8

The Carl Zeiss Jena Flektogon 35 2.8 was the primary prime 35mm lens from the East German Carl Zeiss Jena company during the fifties, sixties and early seventies. It was produced for a quarter of a century before a new, improved 35mm 2.4 Flektogon was released. The 35mm 2.8 Flektogon is nowadays one of the most affordable 35mm “Zeiss” branded lenses you can buy. It is mostly available in M42/Pentax mount and Exa/Exakta mount. At the beginning of the production run, the lens was also manufactured in Praktina mount but in smaller quantities.
PROs:
- Minimum focusing distance
- Loads of character
- Built quality
- Sharp in the center
- Good for black and white photography
- Distortion is not too bad
The Flektogon 35 2.8 is a beautifully made lens, as you would expect from Carl Zeiss Jena. Both the early silver version and the follow up versions are well balanced. Focusing is buttery smooth and aperture settings are easily set. The lenses feel very solid – but also somewhat heavy. Overall the ergonomics are nice and the lens is easy to use.As any Flektogon lens, the minimum focusing distance of the 2.8 version is pretty impressive. The early version has a minimum focusing distance of only “36 cm”, but this was improved to 18cm with the follow up versions. This allows you to get pretty close to your subject.
Image sharpness is pretty remarkable for such an old wide angle lens, at least in the center of the image.
The lens manages to capture a lot of details, which is not a given for an old wide angle lens.
There is some falloff and vignetting in the corners. This gives the lens an interesting look, almost film like look. This can be pretty handy for landscape shots for example. If you enjoy landscape photography and want to have some natural vignetting the Flektogon 2.8 will be a lot of fun. On a beautiful, sunny day you will be able to take pretty shots with a lot of character. If you like slight vignetting and softer corners for a distinct vintage look, this lens is for you.
The Flektogon 35mm 2.8 is also pretty good at keeping distortion to a minimum. Distortion does occur but like with most Flektogon lenses, it is not that bad. This makes the Flektogon 35mm 2.8 an affordable wide angle lens for architectural photography.
Since the lens is pretty prone to flaring and all sorts of effects, it is also pretty nice when you do longtime exposures at nighttime to capture light-trails. If you like your lenses to have a slight artistic imperfection, the Flektogon 35mm 2.8 is a good option as it is very versatile and never gets boring.
The Flektogon 35 2.8 comes from a time when black and white photography ruled the world. And for this purpose the 35 2.8 is superb. The somewhat contrast-less images turn out really nicely in black and white.
CONs:
- Chromatic aberrations
- Flaring
- Slight sharpness falloff in the corners
- Not the prettiest bokeh
- Slight lack of contrast
- Not a forgiving lens
Don’t get me wrong, the Flektogon 2.8 is a great little lens but is has some drawbacks. There are reasons that the 2.8 was discontinued in favor of the faster Flektogon 2.4.
First of all the Flektogon 2.8 can have issues with flaring and chromatic aberrations. The coating used on the 2.8 are inferior to the 2.4, and it shows clearly in a lot of situations. Hard light sources and anything shinny are not the friends of the Flektogon 35 2.8. I would recommend using a lens shade as the front element is pretty exposed.
The lack of contrast can be a bit tedious sometimes. Images turn out rather flat. If you are more into colour photography I would recommend looking into spending a bit more on the newer Flektogon 2.4 35mm.
Another disappointment is the out of focus area. I know that this is totally subjective but I do not particularly like the bokeh of the Flektogon 35 2.8, especially on colour shots. It looks smudgy and loveless. It is rather blurry and not particularly pleasing to the eye. The Flektogon 35 2.4 performs much better when you stop down the lens.
Low light situations can also be tricky. When you shoot inside or at dusk and the light is not perfect, then the Flektogon 35 2.8 really struggles. Which is surprising when you consider that at f2.8 it is not a slow lens. But wide open the lens does not feel at ease. In these situations I would for example rather use a “slower” f3.5 35mm Takumar. Without the right light conditions the Flektogon 35 2.8 images lack clarity. This is where the age of this version of the Flektogon shows.
Overall the Flektogon 35 2.8 is a good and interesting lens but it has a few flaws. I would not recommend this lens to a beginner but rather for a more seasoned vintage glass shooter who wants to diversify the looks in his lens arsenal. It is not the easiest lens to shoot with and results do vary a lot.
