  • alexey_laa

    barycentric - seems to be translated as "center of mass". Maybe we are talking about mechanical balancing, that is, when zooming, the center of mass does not move, and under the weight of the lens it does not begin to tilt the camera.

    • Onotole

      Yes, I also think this explanation is correct. For relatively light cameras 4/3 this should be quite relevant.
      By the way, Nikon 20-35 / 2,8 behaves about the same - when zooming, one part of the lenses travels forward, and the other - back, it may of course not perfectly, but the balance +/- is preserved.

      • alexey_laa

        Balancing is also important when mounting the camera on a XNUMX-axis gimbal. Other reviews write that the lens can be good for video shooting (minimal focus breathing, stepless aperture control). Although video requires a motorized “power zoom”, this lens is manual.

  • alexey_laa

    Regarding 240 fps for autofocus, I found:

    “… 240 fps (frames per second) drive AF on top of it all. That last point is perhaps the one that matters most of all, as both the camera and the lens sync up at 240 frames to take full advantage of your LUMIX camera's high-speed AF system. ”

    Apparently, we are talking about the fact that the focusing system (camera and lens) measures sharpness 240 times per second.

    • Arkady Shapoval

      Thank you

  • Onotole

    I wish someone would make 10-25 / 1,7 (or 1,8-2,0) for Nikon-crop ...

    • Arkady Shapoval

      For Nikon crop, it will be 14-34mm. Has already Tokina 14-20 / 2.0. There is a longer Sigma 18-35 / 1.8

      • Onotole

        No, I'm not talking about EGF but about real 10 mm. Tokina is wonderful, but who knows that there is an abyss between 14mm (EGF 21) and 10mm (EGF 15mm).

        • Arkady Shapoval

          Well, I don’t think that in the near future they will do 10 / 1.7 for APS-C. Because this is only a dream.

          • Onotole

            I do not argue, such requests are very ambitious. However, before the release of the same sigma, 18-35 it was also considered that it was impossible to make a zoom with a constant 1,8 on the mirror system for sane money

          • anonym

            mirror crop is already in the landfill, no one will develop anything for them all the more aperture zoom at 1800 dollars.
            Usually the owner of the crop SLR tells fables how great it is to shoot the whale zoom and can hardly save several years for a fix such as 50 1.8 or 35 1.8. the limit of dreams of the owner of the crop SLR as money is available is to crawl to the full frame (become a mattress owner!)
            let's say, clearly explain why to buy a crop DSLR and not mikru except that crop DSLR is very cheap and merges in large quantities on the secondary, these lovers can not.
            Micra is completely different. first of all, this is a video, including the work of the pros.
            these are owners or former owners of a full-frame mirror, tired of its weight and size.
            for them, if necessary, $ 1800 is quite a normal amount for a high-quality bright zoom. there generally zooms have long exceeded $ 1000.

            • Onotole

              What you are talking about is incredibly interesting and relevant.
              Please tell us more about the advantages of mirrorless systems over zoom systems and crop 2 over FF.

              • Vitaly N

                I already got into the habit of skipping long opuses by Anonymous. Write so many lines and cannot identify themselves in any way - it says a lot. It's especially fun when anonymous people argue with each other. Although it may be the same person ...

              • alexey_laa

                By the way, I have a Lumix G80, and I even thought of writing a review about it. :)

                This is my second Micro 4/3 camera, the first one was Lumix G3. I chose between Micro 4/3 and an inexpensive DSLR. I chose Micro 4/3 for its greater versatility - compared to an inexpensive DSLR, the G3 had Full HD video (Lumix is ​​generally well suited for video), a rotary touchscreen display, more possibilities for installing manual lenses, and smaller dimensions and weight.

                In favor of traditional DSLRs, as far as I understand, this is a more mature and predictable photo quality. Although, in the Lumix G80 it has clearly improved compared to the G3.

              • Michael

                So, mirrorless just blew up the photo market, so for a month now we have been listening to anonymous fables about color, lightness, compactness and what you need to buy and what to throw away

              • Mumble

                “Ugh abyss! - she says, - and that fool,
                Who listens to all the people of the vrat:
                All about points only I lied;
                But there’s no good in them. ”

                Unfortunately, it happens with people:
                No matter how useful a thing is, prices without knowing it,
                The ignoramus about her has a good sense for everything;
                And if the ignorant know better,
                So he also drives her.

            • meridian

              You should not bury the camera. Being the owner of a mirror full frame, crop (D500) and mirrorless dvukrop, I can say with all the confidence that the D500 represents the greatest consumer photographic value for me.

              Advanced crop was, is and will be. And the entry-level crop for some time will perform the primary function of entering the system until the entry-level mirrors of a similar price appear, which intercept the initiative.

              At that time I agree that there is no one to produce advanced lenses for mirror crop now - all the engineering forces are thrown on mirrorless cameras. The greatest efforts, in my opinion, were made by Sigma, releasing 18-35 / 1.8, 50-100 / 1.8. But now she is clearly not up to continuation - she needs to build an L-system.

              • anonym

                crop DSLRs can be of interest for 3 people and even for five as many as you like.
                the question is that for the masses of sales 5 people are unfortunately not enough.
                Therefore, it was already confirmed at kenonrumors that, for example, there will not be a new 7D and is not even planned.
                Although it is quite possible that exactly the top crop of the DSLR will still be there for some time.
                and new lenses and all resources, and Nikon and Kenon are investing in the development of mirrorless, trying to catch up with Sonya.

                All this flood resembles moaning with Nikon 1, when it was obvious to everyone that the system was dead, but the fanboys jumped proving that they were interested and that they would buy everything. or praising nikon df who epically failed in sales and there was a srach on the forums - all nikonists proved that they were already in line to buy. ) In total, they bought 1.5 people and quickly merged them.

              • Samir

                Meridian +1
                it’s immediately clear that the person really compared.

            • Arkady Shapoval

              Should we take mikra for a photo? How quickly will the user feel the difference between her and any d500, 7d mark 2, d7500 elongated from the landfill?

              • Michael

                And feel? Well besides weight-size

              • Arkady Shapoval

                I ask you this, try to answer, since your flood under each post is a little annoying. Let it be at least a little useful :)

              • Michael

                Okay, we won’t. IMHO the difference will only be in ease of management and work in difficult conditions. The average user will not see the difference.

              • Arkady Shapoval

                That's just the point, when it comes to serious, users turn on the back :)

              • Michael

                Not everyone gets it to the serious, in the sense of a sports report, and there the DSLR has no competitors yet. It gets boring to hear about the inferiority of mirror crops and how nobody needs them ...

              • Donotol

                Mikra is primarily for video and travel when weight and size are critical.
                Fanboys of DSLRs can foam and flood a lot, but you can’t take a serious video on the SLR crop, there is no ibis there and will not be there, and for travels when the weight and size of the SLR crop are important and the more so the full frame is not an option.
                therefore, mikra existed perfectly when crop DSLRs were still alive and when serious uncles shot films and clips for the legendary Mark 2.
                oddly enough, the main competitor of mikra is mirrorless full frame. as soon as the prices are equal, most of it will run there, so Panasonic has released the fz in advance, in the fall a new one will already be with 6K video.
                if you need to shoot seals, tops and don’t need to wear a full wardrobe trunk, if you don’t need a video, then the micra is obvious, you just don’t need it. Why flood it?

                anonymous, but this quote fits perfectly with your beliefs, not Pokemon.

              • anonym

                Vitaly N, what place? Take the trouble to read my post and quote first. I hope you know where the quote came from?
                here's a post for you
                “Usually the owner of a crop DSLR tells fables about how great it is to shoot a whale zoom and can hardly save several years for a fix like 50 1.8 or 35 1.8. the ultimate dream of the owner of a Crop SLR, as money is available, is to crawl full frame (become a mattress owner!) "
                what do you disagree with? and where is the belief if it's just facts, read here at Arkady in topics about crop DSLRs on what people take off and what they want to upgrade.

              • Vitaly N

                And who is agitating everyone here precisely for this and painting the charms of FF and mirrorless?
                So I decided to stay on the DSLR crop quite consciously, having recently updated the camera. And I do not need a mattress, no matter how agitated. It is necessary to compare desires, reality and needs. Middle frame owners look at the FF owners just like you. For me, the amenities exceeded the desire to have FF, having a currently limited budget.

              • anonym

                Vitaliy is so wonderful that you are not a mattress owner and that suits you.
                what was wrong with the quote? what did you disagree with?

                "And who here agitates everyone exactly for this and paints the charms of FF and mirrorless?" - this is a market, alas. Crop DSLRs are buried by Kenikon. Full frame dropped in price to $ 1200 and this is just the beginning. they are just facts, whether you like them or not. don't like it - well, don't read about it, ignore the release of three new FF BZ systems, roadmaps for them and sincerely consider that crop DSLRs will still be on the market for a long time. It is also a position in life, it has the right to be.

              • Michael

                Crop SLRs will be buried when they cease to release. So far, all the rules

        Arkady, to put it bluntly, Tokina AT-X 14-20mm f / 2.0 PRO DX is a stretched for focal development of many years ago, which was slightly changed, stuck in a plastic hybrid aspherical. judging by the design, the aperture loop will be frayed by itself and there remains a stunningly uncomfortable AF switching mechanism.
        This lens has very little in common with the latest development of Panasonic.

        • anonym

          Oh, another one with a "hybrid", "train", "stretched", what for what? To do on mikru from 1.7 for 2000 bucks - this is certainly powerful!

        • Arkady Shapoval

          Please note that I am in no way comparing these lenses. It is only about similar focal lengths and aperture, no more. The tokin at APS-C Kf = 1.5x has EGF at the wide end the same as the hero of the announcement, the diaphragms are also close. I would be grateful if you tell me which development lies at the heart of 14-20. Also, I want to remind you that you should not scare people with hybrid aspherics, the topic is being discussed, for example, here. Scare the train, I mean, you can only when there are real facts of its failure, so far this is only a hunch.

          • anonym

            Arkady, about the loops this is not a guess, but the results of numerous failures of previous models with the same design. There were enough disassemblies of these lenses on the net, discussions, and evidence. The new model is too small and sold too little to have data, but by all indications the design has not changed at all.
            Its One-Touch Focus Clutch Mechanism is again unchanged, the design has not changed again, and such switching is inconvenient that anyone who has ever used it understands.
            I also want to clarify - where did I scare someone with a plastic aspheric? Can you quote?
            About development - here is the link
            https://d.radikal.ru/d02/1906/2f/db4e0380fdcd.jpg
            there are three tokin optical circuits for the last ... twelve years, evolution is clearly and clearly visible.
            Quality problems can be clearly seen here.
            https://www.the-digital-picture.com/Reviews/Tokina-14-20mm-f-2-AT-X-Pro-DX-Lens.aspx
            A short summary of Tokin Shirik. At first there was one (!) Development, it turned out to be very successful, it was slightly modified and got a hit. The main disadvantages were huge HA and mediocre AF. Then, in order to reduce the cost on its basis, without straining, they closed up the whole family, playing with focal and aperture. It turned out, as it were, from not bad to so-so. But development of the times of mammoths is by itself incomparable with the latest developments of Nikon, Kenon, Panasonic, Sony, Olik and Fuj, sigma.

            • Arkady Shapoval

              Thanks. You indicated hybrid aspherics as a flaw, which is what was meant. You also forgot to indicate the cost, which also plays an important role in the analysis of a particular lens.

              • anonym

                Arkady, here is my quote
                “The Tokina AT-X 14-20mm f / 2.0 PRO DX is a long-term focus development that has been slightly changed, with a plastic hybrid aspheric. judging by the design, the aperture cable will fray so itself and the amazingly inconvenient AF switching mechanism remains. "
                I didn’t say anywhere that the plastic aspherical is a plus or minus, I indicated this as the difference in optical circuits, no more.
                Fact check at the link above.
                You are right, from a price point of view, any lens developed 20 or 10 years ago will obviously be significantly cheaper, there are no R&D costs.
                For example, yongnu - their lenses are usually developed by a canon 20 years ago in a new way.

              • anonym

                So they would write - different schemes, and it's a no brainer that they are different. They wrote as if plastic is bad. Tokina 2016, even if her scheme is based on something previous, the same can be said about all other lenses. Why don't others upgrade theirs to 2.0 then? Or do you want to say that this sub-model is not based on something older? Tokina 14-20 is wonderful, everything else is nit-picking.

              • Arkady Shapoval

                Yes, most likely I misunderstood the context about aspherics.

          • Denis

            Arkady, you would delete such branches. Such impulsive characters are not inclined to constructiveness, they only cling to words and defend their own. Which, in turn, spoils the impression of the forum.

    • Samir

      Nikon's crop has a similar good glass hippopotamus 14-24 / 1.4, which on crop will give 21-36, and the subject in this regard will be more attractive 10-25 in effective numbers gives 20-50. here the watering can sets a new standard for zoom from moderate super wide to normal. such a seal cannot, by definition, be neither very small nor very light, but the hippo definitely wins, IMHO! that is, my opinion, I do not agree - speak out why.

  • Passer

    In order not to extend the body of the wide-angle zoom, some of the lenses can "go" in different directions. The larger the zoom ratio and the less lenses involved, the more difficult (more expensive) to make the lens length shorter. At shirikov the body is extremely short and balancing one tenth of the mass of the lens is somehow not convincing. The width of the center of gravity, in the vertical and horizontal position, may turn out to be only a centimeter, but if the diameter and length are different at times, then the camera will definitely peck. And material saving. All IMHO.

      To be honest, nothing is clear. Is 13 centimeters an “extremely short lens” in your opinion? Where does the information about 1/10 of the mass come from? And what is “the center of gravity, in the vertical and horizontal position of only a centimeter”?

  • Passer

    A pair of lenses (for sure) is less than one tenth, this is me “by eye”. With a long lens, the camera will definitely peck, and with a short one, it’s a completely different matter. If the glass is long, why balance? Plus, with a short lens, tolerances and backlash are not so detrimental to centering / skewing, etc. optical circuit.

    • Onotole

      The balance is needed as indicated above for installing the camera in the stabilizer. On my own I can add - when mounted on a tripod. The closer the center of gravity of the camera with the lens is selected to the center of the ball in the ball head, the less the load on it and the less the tripod sways. When zoomed in, all this balance is usually lost to hell (for example, 70-300). The fact that the glass is long does not in itself mean that the balance cannot be achieved.
      On a good strong carcass, there is no distortion with any lens, just after a certain size and weight of the lens, you need to hold it not for the camera but for the lens itself.

    How much srach from scratch

  • Passer

    Yes, 13 centimeters and with such a small matrix! Probably this lens has just afigenic parameters. Now, if the matrix were huge, it would be more difficult to push the required 13-10 cm into 25 cm. Probably possible, but you can’t even talk about the quality of the results.

  • Passer

    Optical manufacturers probably have the same share, the staff of engineers and brains get paid for this.

    • anonym

      Producers do not deal with srach. They work.

    • anonym

      The word "srach", by the way, is written without a soft sign.

  • Samir

    it is strange that srach rose, completely not reflecting the subject subject. and the glass will be cool and regardless of the size and cost it will be taken for the amazing quality of the picture. in principle, 120 k per glass of this level is normal.
