    Arkady, good afternoon. Please tell me, but when using Soviet lenses on cameras with ASP-C matrices, the focal length is recalculated in accordance with the crop factor, but in terms of aperture such recalculations should be carried out, and how does this generally happen? After all, lenses are designed for a full frame, and the manufacturer produces its own for matrices with crop and lenses, in accordance with this, the aperture of Soviet lenses on cameras with asp-c will be higher than native optics. Those. if on Helios 44m-4 2/58 close the aperture at f 4, then physically the “hole” will be wider than if a similar operation is carried out at 18-55 3.5-5.6. Am I reasoning correctly?

      Recalculation by aperture does not occur. The light flux density will be the same. Only under the crop, this light flux will fall on a smaller matrix.
      If they said differently, the exposure parameters, such as ISO, shutter speed, aperture, flash output with the same lens on the crop and on the small frame (including the film) for the same scene will be the same (in fact, almost the same, but the details can be neglected).

        Thanks Arkady. Here is a question not in the subject of this article. I shoot with Canon 400D + 18-55 3.5-5.6 is stm, no matter how hard I try, sharp pictures are not obtained, I have already used manual focus, and aperture at maximum, and ISO 100, shutter speed from 250 to 1000 (in the morning it was light and there was time ). I tried to turn on the auto (I only shoot on M), on M I tried objects in the light, landscape and much more, in different versions. I understand that for a clear answer I need to check my photosystem for quality, maybe the lens is defective, although in perfect condition, but still - with what can I achieve sharpness in the photo? Maybe you should switch to Nikon, or you need good optics? Or crooked hands ...

        On aperture 8, almost all lenses show good sharpness. Of course, if they are working and the subject is in focus. In your case, it can smear the camera, it can smear the lens. Find someone with Canon and check, exchange lenses, take a photo. I don’t think it’s so complicated.

        Take it off the tripod (an option - put the camera on the table if there is no tripod), but I can't imagine how much hands must tremble to give blur at such short exposures.

    “And then there are some very interesting CCCP lenses with an interchangeable shank. To use on a Canon camera, it is worth installing two adapters KP-A \ 42 + M42 - Canon EOS on the lens. Well, or quite with the perversion of KP-A \ H + Nikon mount F - Canon EOS. "

    So there seems to be one adapter: T2 - EOS or something I confuse?

    Now I want to ask. I found a Vivitar 90-230mm f / 4.5 lens and I can’t understand whether it can be used on modern cameras? There is a replaceable shank T4 / TX-mount, could not find the information. Most likely I was looking badly. Thanks in advance!

    Hello. I would like to talk about one unpleasant moment. On Canon DSLRs, and especially Nikon, m39 threaded lenses, even SLRs will not quite focus on infinity. The fact is that they have a working distance of 0,3 mm shorter than that of the m42. Accordingly, the adapter for them should be 0,3mm thinner. But, unfortunately, it is almost impossible to find such adapters, because this standard, unlike the m42, as well as the range-finder version m39 (working distance 28,8) is purely Soviet, and our Chinese friends unfortunately do not make adapters for purely Soviet standards . This problem can be solved by grinding the surface of the adapter onto these 0,3 mm.

      Even if you cannot find a thread in a reference book or on the Internet, you can always try it on. Any competent locksmith, having an appropriate thread gauge, can do this for you in 2-3 minutes. But you can also go to some center where cameras are repaired - there the repairmen will probably tell you.

    Hello. Tell me, you may have encountered: I installed Helios 44 on a canon m50, through an adapter without a chip. Everything is fine, live view shows the focus area. But the shutter does not release. That is, it does not programmatically include video recording, photo snapshot. I press the buttons - it does not respond. With the native lens, everything is ok.

    Good afternoon!
    Could you tell me if the excerpt from this article applies, namely: …… ”Some lenses require improvement of the aperture control method. Usually it comes down to the fact that you need to block the mechanism of the blinking diaphragm, so that the diaphragm can be controlled manually. ", To the Zenitar-M 1,7 / 50 lens? Would like to try it on Canon 7d via M42-EOS adapter.

    Good day!
    Does anyone have experience using different adapters with chips.
    According to personal feelings, confirmation of focus is very slow, often the camera skips when you several times walk along the same point without confirmation. Maybe it's in the chip. On Nikon the same camera is much faster focusing is confirmed, the first time it hooked a point.

    Is there an option to use these lenses, so to speak, at full speed? Lenses suitable for a full frame can, after all, be connected to cropped devices through a speed booster and use the capabilities of a full frame on a crop. Is it possible to somehow contrive to connect some Helios to my Canon 650D carcass?

      Such a speed booster, in addition to shrinking the image, must also change the working segment. Either the circuit becomes more complicated, or the quality is worse. I don’t remember that it came across.

    Not sure what options in manual mode are there in EOS besides LiveView? Now I use Nikon D5000 - there in the viewfinder the green circle of the rangefinder lights up when you get into focus - very convenient and accurate (for me with my vision). With bursts of 3 frames with shutter lag 1-2 are sharp. I feel uncomfortable through the LCD screen, and the battery runs out quickly.
    I want to try some sprinkled EOS to get infinity on old M42 and M39 lenses.
    Questions:
    1. Is there some kind of EOS model with a rangefinder like the Nikon green dot in the viewfinder.
    2. If so, will it work with a simple mechanical adapter without a chip.
    3. If without a chip in any way, then how to drive the lens data into it?
    4. Do I need a separate chip adapter for each lens?

      you need an adapter with an EMF chip, it allows you to program a focus confirmation correction. Moreover, for the accuracy of this action, the aperture value 1.1 must be programmed in the chip, but the FR value can be any, it does not affect anything.
      but shooting in LV is very convenient. I wrote a lot where how to do it right with the help of ML.

      At Canon, the focusing screen is darkened non-linearly with aperture cover. This is taken into account when operating the exposure meter. Therefore, the camera will give different ratios of e-couples depending on the parameters sewn into the dandelion. Crooked, but somehow

        And then how will he measure the exposure if there is no chip at all?
        I've taken an adapter without a chip, now I'm racking my head about how the exposure meter will behave (camera kenon eos 300, film. When installing the adapter, it writes the aperture value of 00, and in the M mode it even tries to show the exposure scale on the exposure scale, but to change the aperture value of the exposure answer inadequately, IMHO. And it will be possible to check all this economy only after snapping off the entire film)

        a hundred times written on all Internet zabra - kenon measures exposure even on an empty bayonet. but Nikon can't do that. only the elders can, if the parameters of the optics are registered in the camera.

        I don't prescribe anything, the D800 measures the exposure on all lenses. I do not understand at all what needs to be prescribed there if the matrix illumination is measured. Only the diaphragm is not displayed correctly, but this is already from the category of "the best enemy of the good"

        Maria, the exposure is measured not on the matrix, but on a separate exposure sensor. It sits on top of the prism, next to the viewfinder.

        They don’t hurt, the adapter is very thick (long), 3-4 times longer than the rear protrusion, this is an adapter from a mirror lens to a mirrorless mirror, it compensates for the working segment (that is, the place where the mirror was, etc.).

    Good day.
    I am interested in this question. Actually there is a Helios 44th lens and a Canon EOS M mirrorless camera with a 1,6x crop. A conventional adapter multiplies the crop factor and the resulting focusing area is 93 mm.
    Perhaps there are adapters that would level out the crop and Helios 44th gave out its standard focal length, as in a full frame?

    Reply

    • twm
      23.08.2020

      Alexey, each lens is calculated for a specific area on which it will project the image. The crop factor of aps-c matrices is essentially a direct indication of which part of the viewing angle should be cut off when a full-frame lens is used on an aps-c camera.

      For Helios, with its 58 mm FR and ~ 40 degree viewing angle, 1.6 crop will give an angle of view of 25: in other words, the crop sensor simply does not capture part of the projected image. You can return the “full angle” either by purchasing a camera with a “full-frame” sensor, or by purchasing a speedbooster adapter - ie. an adapter with a lens that will "collect" the image produced by 35 mm optics and project it onto the crop matrix.

      But such an adapter costs a lot of money (from ~ $ 70), and I don't know if there are EOS M versions for m42 lenses.

      The adapter itself does not multiply anything, the crop factor appears only due to the smaller matrix size.

    I uncovered my filming skills here. I bought a Canon EOS 50 for inexpensive, an adapter from Helios 44 to EF with and without a chip. And here's what is strange: the adapter with the chip seems to cling to the mirror: the camera no, no, and it will hang, throwing the mirror back after the release, and waits for me to reboot it. I look - an adapter with a chip with a bevel literally millimeter. And without a chip - without a chamfer.
    But that was not the case: I sealed the chip with electrical tape, as if it was not there. I put on an adapter with a chip and electrical tape. And made the camera take pictures. And she did it without freezing! That is, the matter is in the chip ... And this is the second adapter with a chip already like this ...
    The EOS 50 skips a frame at least (at least counts down). But the EOS 500n doesn't even do that, so every time after such a freeze one frame is damaged.
    I don't understand what this is :-( I want to somehow shoot without this freeze, although at the 50th, it seems, the frames do not suffer because of this.

        So it’s clear: also a way out. But I wanted to get an assistant with focusing: the old cameras have a mirror that is very inconvenient for manual focus (and I want to use old lenses).

        In this case, I took a Canon EF-M with Doden wedges. But EF-M is all unsightly, you can't choose exposure meter modes ... Dilemma :)
