Danubia Brief 1: 8 f = 500mm

This lens fell into my hands by accident.

Danubia 1: 8 f = 500mm

Danubia 1: 8 f = 500mm. increase.

In short

Danubia 1: 8 f = 500mm is a modern very cheap super telephoto lens for cameras with different mounts. The lens uses the T2 interchangeable shank system. The review shows a version with a shank for the Pentax K mount. Most likely Danubia 1: 8 f = 500mm is sold under other names, for example, JINTU 1: 8 f = 500mm.

Danubia 1: 8 f = 500mm uses manual focus only. Poor image quality. Very light weight (as for this kind of lenses).

First of all, the Danubia 1: 8 f = 500mm lens is interesting for its low cost, huge focal length and 14 aperture blades.

Shooting with Danubia 1: 8 f = 500mm is difficult. The lens requires a powerful tripod. Take off hand it is possible without problems only at very short shutter speeds, in the region of 1/2000 seconds, and this requires high ISO values ​​(remember, the maximum aperture is only F / 8). Due to the fact that the lens is very light and long, it 'shakes' a lot (the picture is blurry when shooting handheld).

Assembly, control, focus

Lens body assembled not bad. The focus ring has a wide anti-slip insert made of hard rubber or similar material.

The diaphragm has fourteen blades. At any aperture value, the aperture has a regular rounded shape.

Danubia 1: 8 f = 500mm uses small filters with a diameter of 67mm.

Focus ring Danubia 1: 8 f = 500mm rotates approximately 180 degrees (half of a full turn). During focusing, the lens trunk extends forward and rotates with the front lens and filter thread. The rear lens remains stationary during focusing. The rotation of the focusing ring is very smooth and pleasant.

It's important: The minimum focusing distance is approx. 10 meters... This gets in the way when shooting small objects.

Danubia 1: 8 f = 500mm has a ring for setting and presetting aperture 'O <-> C'. Use the aperture control ring to set the desired value. With the help of the 'O <-> C' ring, at the right moment, the diaphragm is physically closed to the selected value. This implementation serves to always focus on an open aperture, the aperture closes only at the moment of shooting.

The lens is equipped with a tripod foot. The foot has a nice metal clip. The foot can rotate 360 ​​degrees freely

On the body there is a scale for focusing distance in meters and feet and a DOF scale.

Image quality

Danubia 1: 8 f = 500mm is optically weak. First of all, at an open aperture, there is a noticeable amount of spherical and chromatic aberrations, as well as a low resolution. With the aperture closed to f / 11, sharpness bounces back. At the same time, sharpness practically does not sag to the edges and corners of the image. Unfortunately, the lens has poor contrast and does not tolerate backlight very well.

Camera used Sony α3500 (Sony ILCE-3500) based on EXMOR APS-C CMOS 20 MP sensor. All photos are JPEG straight from the camera. Shooting from an inexpensive monopod. Source codes here.

Results

Danubia 1: 8 f = 500mm is a very controversial lens. The user gets exactly what he paid for. Danubia 1: 8 f = 500mm needs a good tripod, which will allow shooting at apertures of f / 11-f / 16 (for better image quality). Most likely analogs (or clones) by type JINTU 1: 8 f = 500mm are no different from Danubia 1: 8 f = 500mm.

  • Dmitriy

    “Sources” are RAW files, when reviewing digital photographic equipment and, in particular, lenses, only a RAW file can be viewed to get an idea of ​​the parameters, when will you understand this?
    More photos from the mobile phone scans of photos printed on an inkjet printer would be laid out as examples.

    • Arkady Shapoval

      Not necessary

    • Joe

      "To get an idea of ​​the parameters" you can look at the metadata in jpg. You have not given any reason why raw is preferred over jpg as raw materials when reviewing this lens. But raw has at least two drawbacks - a larger size, which potentially leads to higher hosting costs, and the need to have a raw converter for viewing with support for the cameras that were used for shooting. At the same time, raw compared to jpg does not provide any significant additional information to get a general idea of ​​this lens.

      • Dmitriy

        Well, if you prefer to judge a picture by its copies, then this is your right, a camera JPG is a “copy” of RAW with its own improvements, the white balance is set to an average statistical value, the detail is adjusted by an in-camera converter as it is set in the camera, the same the most with contrast, saturation, everything is according to the camera settings, and each camera and each manufacturer has their own vision of these settings, but RAW gives the most accurate representation, although it also depends on the matrix manufacturer, but this is, so to speak, “the first copy”. And with the size, now it is not as tense as 10 years ago, hosting "rubber" for a long time.

        • Arkady Shapoval

          Of course, I understand what you are talking about, but still I can't help but play a joke:

          You will still be looking at the RAW after debayering (i.e. the original RAW you will not see). Then what algorithm will you use to see the image, there are 9 basic ones? Or will you still look in the original rgb-gray palette, such as the one attached here? (this is exactly how + - RAW is encoded) and already from this “green” image through the RAW digger it will draw conclusions about the lens :)

          • Dmitriy

            I will greatly surprise you, with your own methods:
            human vision is extremely mediocre, and depends on the proportional ratio of certain types of sensitive cells in a very small area in the center of the retina, if the proportions are slightly changed in relation to the average, then this is interpreted as color blindness, the area of ​​the retina in the center is the size of a poppy seed and has a very mediocre parameters of detail (in the common people - sharpness) and the image is added by superimposing "frames", in the same way as in Photoshop they improve the picture and minimize noise, everything else that we see is completed by the brain and looks like a dull spot, so we see the wrong thing what really is, but what nature allowed to see in the process of evolution, also with converters, there is nothing absolute and correct, there is only some approximate and averaged, but the source codes must be minimally processed to understand the quality of optics and equipment, here is that's what I got started for those RAWs.

            • Arkady Shapoval

              I was not surprised, and I did not hear from you about the original palette how you will debayerize.

              Seriously though, the original RAW is tightly tied to the original developers. In the rest of the developers, we will not see what the engineers put in the camera. That is, we will see a distorted reality. I have a video on this about.

              By the way, over the past many years, this is one of the few reviews where I was too lazy to upload RAW. In the previous review Pergear there is RAW with a3500, you can enjoy it.

              In general, RAW is very important for a camera, because it partially characterizes the capabilities of its sensor, but for viewing the same lens, RAW is often not something that cannot be discarded, especially for cameras that do not correct basic distortions (distortion, vignetting, aberrations) ... In the case of Danubia, this is exactly the case. Cameras simply do not know what kind of lens it is and their software does not include correction parameters

              • Dmitriy

                For the layman, the converter used for debayering is not so important, usually a person gets used to working with any one, and from this he proceeds, he is already accustomed to the final color rendering to the color temperature, it's like a low-quality tape measure, where a millimeter is not a millimeter, if you take measurements for her and measure out the blanks with her, then everything will be exactly the same, and here, the person is already accustomed to colors, contrasts and can easily form his own opinion about the color rendition, distortions of the presented lens, but it is difficult to do this using the in-camera JPG.

  • Sergei

    Leica had a Telyt-R 560mm / 6,8 lens
    which had only two lenses (one achromatic gluing).
    And no one expressed any complaints about the quality of the picture at that time of film.
    True, and weighed much more.

    • Artyom

      That's just a problem, now it's 2021)))

      Previously, they removed the wooden box and did not complain, times are changing

  • Koba

    Pentax cameras have a built-in stabilizer, unlike other DSLR cameras, so it will be possible to shoot with this lens at shorter exposures, moreover, Pentax cameras produce low-noise images of very high quality.

    • Andrei

      "Pentax cameras have a built-in stabilizer, unlike other DSLR cameras ..."
      Coba, have you heard of Sony or Konica Minolta cameras?

    • Arkady Shapoval

      about “low-noise images of very high quality” is a moot point, since there they are all cropped, except for two K1 / K1 II. And all of their sensors are Sony sensors, which are also used in Nikon cameras and make noise + - the same sensors as in Nikon, Pentax, Sony (when it was still doing SLT / DSLR) the same.
      And now, almost all UPCs also have a built-in image stabilizer, so the mirror Pentax no longer has a particular advantage. In addition, in the convenience of working with manual optics, the mirror Pentax loses to almost any mirrorless.

  • Oleg

    I would like to translate the name of the lens into Russian - Danublya.

    • Joe

      Danube is the Danube, Danubia is a region in the Danube basin in Central and Eastern Europe.
      A Russian example of such a name would be “Volga Region”.

      • Arkady Shapoval

        Privolzh'e 500/8 - and will be sold like pies

    • Arkady Shapoval

      Or "Dubina"

  • Oleg

    I tried to joke.

    • Oleg Shevchenko

      The joke was not appreciated. Danublya to buy this, that's for sure.

  • Sergei

    I have his twin brother ... Only under the KIMUNOR brand. Here's a single shot from a tripod. Both for the Moon and the norms of TV sets 🙂

    • Max

      Very much nothing like a cheap lens.
