Triplet-69-3 4/40. Review from the reader Radozhiva.

Overview of the non-removable Triplet-69-3 4/40 (BelOMO) lens of the Viliya-Avto camera transplanted to the EF mount specifically for Radozhiva, prepared Rodion Eshmakov.

This review will be short because there is practically nothing to review.

Triplet-69 is a regular lens of the Viliya scale cameras, with which many began acquaintance with photography. More than 3 million cameras were released; the lens is extremely affordable and widespread. Moreover, it is non-removable, i.e. alteration is required for use on modern cameras.

Features Triplet-69-3:
Optical design: triplet
Focal Length: 40mm
Relative Hole: 1: 4
Field of view: 55 degrees (for 35 mm film)
Aperture: Lens, Square, Auto
Features: fixed lens, aperture separated from the lens block, built-in central shutter.

Features of adaptation and constructive T-69-3

It would seem, what surprises can await after the T-43 during the rework of his "brother" T-69? It turned out - they are enough. Despite the idea of ​​adaptation common to the T-43, a number of features surfaced when working on this lens.

And the first one is the zlinsovy diaphragm, which is controlled by automation. When remaking, there is absolutely no place for her - it is simply not clear where and how to place it, what to manage it. Therefore, it was decided not to bother and, for testing, to make the lens without a diaphragm. What a pity - it would be interesting to get photos with his own square aperture.

The second problem was a helicoid, the stroke of which is rather small, and the thread pitch is large - at the same time the lens block can make a maximum of half a turn, and (taking into account the absence of an MDF stopper) it will have to be caught further, which is very inconvenient. The T-43 helicoid has a small thread pitch, due to which such a problem does not arise - you need to twist the lens with very great enthusiasm so that it falls out.

The third feature, on the contrary, is positive: the lens has an unexpectedly large back segment, which is why adaptation for full-frame SLR cameras is possible! With the T-43, this number will not work - its rear lens sticks out very far. Strictly speaking, it was this feature that caused the desire to get something from this small lens.

It can be noted that the lens cannot be completely redone for SLR cameras (with an aperture and convenient focuser) without investing significant funds and effort, unlike the LOMO T-43. However, this lens can be used on full-frame SLR cameras, unlike the T-43, which is a decisive advantage. On mirrorless cameras, adapting both the T-43 and T-69 is almost equally simple.

Optical properties of T-69

As the simplest anastigmat for cheap cameras, the T-69 at the open aperture forms a sharp image only in the center of the frame. Even on mine 600D the edges are drowning in chromatics, coma and astigmatism. It's a shame that due to the lack of aperture it will not work even to try to get a sharp image across the field. The presence of vignetting is also clearly visible. Contrast can be rated as satisfactory.

But the inherent T-69 bouquet of aberrations can be interesting in the field of art photography. Due to optical imperfections, the lens has an interesting twisted bokeh.

Sample photos on Sony A7s:

I can’t say that the lens impressed me like the T-43 - the latter seemed to me to be of higher quality and, of course, convenient to use and adapt. Take a look at the topic Triplet 69-3 4/40 from the Silhouette-Electro camera.

Conclusions

T-69 - a lens unsuitable for full adaptation for SLR cameras. Optically, it is close to the widespread and famous T-43 from Smena-8. The main and, perhaps, the only advantage of this lens is the ability to mount on full-frame SLR cameras, which will allow owners of expensive monsters to receive photos, like from family albums of the 80s.

  • Alexey Shch

    And I just started to miss Rodion))

    • anonym

      Another review is about nothing. Amused by this - "the opposite feature is positive: the lens has an unexpectedly large back section, which makes it possible to adapt for full-frame SLR cameras! "

  • zengarden

    Yes, there is no point in using it on a modern figure; but, probably, it was interesting to tinker with him :) Thanks for the review, Rodion.

    • Rodion

      This "tinkering" well, somehow it was quite an amateur, to be honest.

  • Victor

    Oh, finally again that Radozhiva that I love so much! By the way, inspired by your handicrafts, last fall I unleashed my grandfather's "Vilya" and tried to put the hero of today's review on Sony E, but nothing good came of it precisely because of the large back section, it turned out only macro. Apparently, in order to use it normally at the UPC, you need to model and print a special adapter on a 3D printer ...

    • Rodion

      If it turned out only macro, it means that you just didn’t have enough working length and you need to deepen the lens block)

  • Stepan

    Where are the meanings? Where are the results? Ideas? Photo?

  • anonym

    Thanks for the interesting review. Inspiring to experiment.

    • Yuri Molchanov

      Thanks for the interesting review. Inspiring to experiment.

  • Alexey

    And if you put a front diaphragm lens?

    • Rodion

      This is not a projection 90/2 - here the vignette will be from this option. It is possible, if you lay down 5 thousand rubles, to make a lens with a za-lens diaphragm, but with a different aperture. Non-native. But who needs it at such a price?

  • Kamil

    Why not just cut out “diaphragms” out of black cardboard?
    In the center of clean Helios-44, I did not see any interesting artistry

  • Alexey de Paris

    Thanks for the review, maybe something shifted during the rework? for example, a lens ... If the picture is on the crop, then what was it on the full frame?

    • Rodion

      The lens block did not understand.
      In full frame ... Look at the photo of Viliya)

  • Andrei

    Viliya-Auto is the worst Soviet camera that I have ever met.
    The quality is so-so, but the price and dimensions are not the smallest.
    The change is essentially the same, but it was almost 2 times cheaper, and in photo schools it was handed out at all.

  • Ilyas

    Well sooo ... you can indulge)

  • Koba

    In my opinion this is an extremely valuable review. The fact is that now it is already possible to safely use any lens from any manufacturer in any condition and not worry about the quality of optics, etc. If by this, in fact, optical garbage, one can get such frames as are shown in the examples, then what is there to talk about? Everything else depends on the photographer himself and his skills. Thanks for the review again!

    • Rodion

      Thank you for your health.
      Yes, given that I made the footage just for show ... Perhaps a thoughtful application will reveal it.

  • Rodion

    The lens reappeared for several days in my hands, so I was able to add a photo from a full-frame camera.

  • Eugene

    Good afternoon! First of all, I have a question - can you please tell me how to remove the lens from Viliya? There are no screws on it, everything is covered by the outer lens housing.

    • B. R. P.

      The camera body is disassembled, most likely.

    • R'RёS,R ° F "RёR№

      A round nut with slots is unscrewed from the inside of the camera.

  • R'RёS,R ° F "RёR№

    I unscrewed the Triplet from Orion, experimented with the diaphragm. I changed it to control not a standard lever, but a shutter speed ring, the mechanism of which, together with the shutter, was almost completely removed except for the figured brass ring. On this ring, I fastened a leash-fork to the glue with a screw, which goes into the cut off the diaphragm lever, into its thin part. I checked it by putting it on Nikon 1 - everything worked out, now you need to invent a mount. On Nikon 3100, only macro is obtained, it is necessary to cut the skirt of the case.

  • Yura

    Tsіkavі photos viishli (especially on Ff).

    Є, maybe, in whom the square is on the 4/3-th. Theoretically, on a microcircuit of an object, it is a regular one))
