    The alternating curvilinear field of sharpness is associated precisely with attempts to correct it. In this sense, this lens is not unique.

    About high aperture. I recently bought a speed booster adapter (focal reducer) 0,71x for installing lenses with a Nikon mount on a Micro 4/3 camera. Allows reducing exposure by 1EV. Thus, if we take Nikkor 50mm 1: 1.4, then with the adapter we get a 35.5mm 1: 1.0 lens.

        Adapter to adapter.
        I purchased a Viltrox EF-EOS M Speedbuster 6X adapter for my Canon EOS M0,7 yesterday.
        I shot test shots with Canon EF 40 / 2,8 STM pancake with and without adapter.
        The difference between the images is only in reducing the focal length of the lens-adapter bundle and in reducing the exposure by 1 step.
        The sharpness in the center of the picture and at the edges is visually the same as with the adapter, that without it, however, I iris the lens to 5,6-8.
        Color reproduction and contrast also do not change.

        It is clear that additional optics should introduce distortion into the image. Now I’m shooting more at him. I also read in the description of such adapters that they increase sharpness (or rather MTF). This could be explained so that the unsharp elements of the original image become smaller relative to the size of the new image after the adapter. While I understand it. :)

        Comments on the article were filled with comments on another topic. I'm not on purpose. :) There was an idea to write some review on your adapter. Such an adapter is interesting for crop cameras in that it uses that part of the image of a full-frame lens that is not used with conventional crop. For cameras with a crop factor of 1.5, the lens with the adapter should give the same image on the smaller sensor that gives the full frame.

        Arkady Shapoval, let me disagree, it all depends on the quality of the optics used in the speedbooster, it's not for nothing that the more complex the optical scheme and the more low-dispersion lenses, the better the lens. Tested on Canon EF 50mm f1.8 STM. At F1.2 aperture, wonderful photos with excellent detail within the depth of field, even a half-length portrait of two people with excellent detail, made a comparison with the Sigma 18-35 f1.8, I did not notice any particular shame except the depth of field, although the landscape is sharp at the edges at F6.3 .XNUMX

      You won't get aperture 1,0 and the corresponding blur, because the aperture value on the lens does not physically change.
      Only the light transmission of the lens-adapter bundle will increase by 1 stop, which will be accepted by the camera's automation as an increase in aperture.
      Example: in the adapter-lens bundle (Canon EF 40 / 2,8 STM), the camera processor sets the aperture value on the display to 2,0, although the aperture value is set to 2,8 on the lens itself.

        In the sense of? And what does the number of apertures on the lens have to do with it, if the speed booster changes its physical scheme - makes the focus smaller while maintaining the absolute aperture? It really will be 35/1, the only trouble is that distortions of higher orders will climb and eat up the quality.

        Standard aberrations - coma, astigmatism, spherical - are geometrically represented as third-order polynomials, as I recall. Beam distortion is described by a formula of this kind and makes the greatest contribution to the drop in image quality and its deviation from the “ideal” one. Higher-order aberrations are described, respectively, by degrees greater than the third.

        It turns out that the modern shirik is some kind of long-focus medium-sized lens (conventionally), to which a speed booster was attached, or even two, because of which it requires such disproportionately large front elements?

        I'm not sure about the widths - traditionally it is more of a telephoto lens turned upside down with an enlarged former rear group to provide a large angle of view (retrofocusing).
        But here 7partisan 35/2 from the previous review is essentially a tessar with a speed booster, which is funny enough. A similar technique was used when calculating a 50 / 0.7 Zeiss planar - there is a massive rear lens group that plays the role of a collecting system.

        This is just not it - Jupiter-12 is the analogue of Biogon, which was obtained from Sonnar. In other words, this is an extreme version of the development of the 50/2 type standard Sonnar lens.
        “It” is Mir-1, for example.

    Yes, in China this lens is sold for $ 130, as it turned out, for Canon M, Nikon mounts (no mistake - Nikon, although which mount is not indicated), Sony, Micro 4/3, Fujifilm. A very interesting lens, it has all the drawbacks, but this is what can be wrapped in interesting photographs in some cases, otherwise the world is already a little tired of completely fixed, large and expensive lenses. 35 / 1.2 and weighs only 160 grams, and with F4 it gives a sharp picture, that is, in fact we have two lenses in one, sharpness is required (usually it is required at closed apertures) - please, a fancy blur is required - for God's sake! There is no autofocus - it is for the best, it will last longer, and if it deteriorates after a few, then lose a little. Personally, I would buy such a lens and try to shoot it in the evening or even at night, somewhere in the Chinese villages (it's a pity that my FujifilmX-E2s does not have a built-in stabilizer!) ...

      as it turned out, they really have one, but for a full-frame Leica it costs an exorbitant $ 430 ... It's amazing that this lens has very good sales in China and users gave it the maximum average statistical score. Dig deeper into the reviews and it turned out that formally it does not have special glasses, but in fact all the glasses in it are made of crystal, so it is so heavy and will probably give a picture of old watering cans or fochtlenders. It will be really interesting to test it here, but this is from the realm of fantasy ...

    I looked at the examples and made a conclusion for myself - it is very clear that this is an ultra-budget lens in the best Chinese traditions (a lot of aperture is almost for nothing, indistinct loose color rendition). I compared it with my masterpiece Kamlan 50 \ 1.1 Mark II - which gives a premium picture in all respects. But this 35 \ 1.2 on the open is worse even than Kamlan MK I, which have already appeared on the flea market for a penny.
    In addition - I have 3 Sony E APS-C cameras including the A3500 and none of them have ever seen color shift matrices with both Camlans. Just my opinion - I could be wrong about the 7artisans brand

    On the open - it's funny, soap, but a kind of "with a karakhter". You can even play around.

    And why should they shoot at f / 8, I don't know, then AF should be taken ...

    I’m wondering what these Seven Handicrafts have with serial quality?
    Once played with CCTV, like all sorts of Fujians, there really are two out of ten you can’t suddenly find two identical ones in the picture (as well as in workmanship, hehe).

    But the price of Fujian is a ruble per bundle, and these guerrillas somehow don't want to buy in bundles.

    Arkady and other experts, there is a question - not really about this lens ... In short, in the review of some lens on this site I came across the phrase: “... this lens has a large depth of field ...” (it seems that there was a talk about some kind of GDR but never mind). Does this mean that the depth of field also depends on the optical design of the lens, or what other features besides distances and aperture? And if so, which 35 has the most depth of field compared to others, all other things being equal? I want to pick up something for shooting offhand (27 is still a bit short).

    It is a pity, Arkady, that in this review in the cards of examples you did not indicate the aperture on which the pictures were taken. Indeed, in my opinion, for the characteristics of the lens in the pictures, this is much more important than the value of shutter speed and light sensitivity.
    Of course, the lens is quite interesting, although it is clear that f / 1,2 is more of a marketing feature here than a really working aperture. But with what aperture and how the lens pattern changes according to your examples, alas, it is not clear. Although, in any case, this lens is probably better than the old, even branded lenses, it is not known how many times they fell and got over, and besides, those sold on the secondary market are sometimes twice or three times more expensive than these “seven masters”.
    I can imagine how much you have suffered, shooting with the open camera on the Sony A3500 - after all, despite the good matrix, the viewfinder and screen of this camera are simply awful and are only suitable for building a composition. By the way, my focus-peaking on it was also not very intelligible on the open one on many lenses - on Helios-103, Jupiter-8, Jupiter-11, Industar 69. With coverage up to 5,6, it begins to more or less highlight the contours. Even on the third model of the Nexov picking, kmk, it works better.

    Among the alternative super-fast prime lenses, you cited a Neewer lens. I would like to throw my own ... well, opinion at this Chinese manufacturer))). Bought them 3! top-end flashes for the Sony E system. I was puzzled by the search for a transmitter to build a full-fledged wireless flash light kit. Faced the fact that this transmitter is not supplied to us - in the USA - yes, to us - no. (In general, many of their products have a typical lifetime for Aliexpress - today a hit, and three months later, following the link to the product - a 404 error.) Transmitter ordered and bought on ebay. The purchase came without instructions. For a long time I tried to find a support section on their website with a transmitter control circuit - alas. The site does not contain absolutely any documentation on the products that this company allegedly produces (in fact, as I later realized, clones of the same products are sold on Ali under different brands and Neewer is just one of them). In addition, from time to time the site was hacked (or maybe the TIC was increased) and, mainly on weekends, instead of the catalog of photo accessories from the monitor, there was porn. In the end, I wrote to the company, described the situation, listed the order numbers in which I bought their products, asked only to send a pdf with a description of the purpose of the trigger buttons, well, or at least give a link to download. The answer was “Dear friend (they all are“ dear friends ”), thank you for purchasing our company's products. Please look for the manual for the transmitter where you bought it ”))). Everyone decides for himself what a company is worth with such an attitude towards its customers.

        Do you think a person writes a review just like you do your comment, or thinks over what he wants to say to the reader, trying to confirm what has been said 10! footage shot at different locations? I have been reading Arkady's reviews since then, when you probably did not even hold the camera in your hands, and these 7 partisans are far from the first manual lens that he reviewed. Let me tell you a secret, for the most part, all of them have aperture values ​​“not transmitted to the camera” (horror!). And nevertheless, in most reviews, the aperture value is indicated in the picture. (You are probably right, and it was not without a notary). Moreover, if you have heard of such devices as film cameras, most of them do not save))) the parameters of the picture, but somehow the reviewers manage to specify these parameters. If we are talking about a technical review, for which most of us come to Radozhiva, then the aperture value is perhaps the most important parameter of the image, by which one can judge the quality of the lens, and it is the ISO and shutter speed that characterize the camera more, therefore, consider the attached frames without the value of the aperture and guess - "here is still 1,8, or already 2,2" - about the same as watching videos on Youtube. There, too, nothing is "transmitted to the camera"))))

        The aperture value as a whole is clearly visible in the picture, as well as in the combination of ISO + shutter speed. It is impractical to write down the aperture value for each photo - this is not a shooting, but a torment that is not worth it.
        When I need to show something to readers like you, I use a special test series of images with fixed aperture values, which do not carry any artistic semantic load. However, this is not important for every lens.

As for your ability to determine the aperture by ISO + shutter speed (I hear this for the first time, learn to live)))), can you determine whether the cats in the third row of photographs were taken at the same aperture or at different ones? The shutter speed and ISO are the same in both frames, but the lighting differs by at least two stops. And, navangyte, please, what aperture is there? Already f / 4 or still f / 2?
