Carl Zeiss Jena Flektogon 35mm f2.4

Carl Zeiss Jena Flektogon 35mm f2.4

To put it simply; I love this lens. On my E420 it has a focal length equivalent to 70mm, which is a rather nice portrait focal length or any general purpose really. It’s not a really a conventional landscape lens, but can still be used to take landscapes. Although not the brightest of lenses f2.4 is generally good enough for most low light situations or freezing motion in good light. The best thing about this lens though is its very close focusing distance, which on my E420 is almost standard macro yet with extension tubes it becomes a super macro lens !

The close focusing distance does result in large movement of the front element when focusing.

The build quality is generally good although not as solid as some other lenses, metal all over with a fair weight, yet the focus ring is a bit stiff and not silky smooth.

Image Quality Test

At f2.4 things are a little soft (probably due to the shallow depth of field) by f4 things have sharpened up with a small increase at f5.6. By f8 things are looking nice and sharp with f11 only showing a small increase, f16 is almost identical and f22 shows a miniscule drop in sharpness from difraction. Generally I am happy with these results, especially how small the drop in quality is at f22 which is much better than my Olympus Zuiko 14-42mm.


Here are a few of examples of pictures I have taken with this lens.

For macro shots this lens will offer bags of detail, great contrast and a nice close focusing distance.

Also useful for portraits or in this case; the zoo. The relatively large aperture helps in the low light and gives pleasing backgrounds. Yet be careful with focusing, I was slightly off in this shot !

Finally it is great at bringing out fine textures such as on this flower.

  2. Thank you for the review. Loved your pictures and they really helped me in making my mind up to purchase this lens. I really love its closeup capabilities and a bit worried about its focussing performance for landscapes. Do you have any comment on it ??

    • Thanks for your kind comments ! 🙂 As for Landscape focusing, it will really depend on your camera. If it’s a Canon, Olympus, Sony or Pentax it will be absolutely fantastic, just as mine is. Yet if it’s a Nikon it will not be able to focus to infinity (a long way off) so you will struggle with Landscapes. It really is a superb lens and I would highly recommend it, hope you purchase it to enjoy it as much as I do !

  3. Your test is very helpful. I just bought one. Yes is pretty soft at F2.4 and its start getting better @4…up to F11.
