  • Neopulse

    Wait, you sure it’s Bayer and not X-Trans?

    • The specs say: “Sensor developed by Fujifilm”
      I had guessed it was a Sony sensor, maybe not.

      • Les

        It can be fabricated by Sony but designed by Fuji. Similarly, Apple smartphones contain some chips that are designed by Apple but fabricated by Samsung. These chips are built on the same process that builds chips for other customers, but the implementation (the “special sauce”) is different. For instance, Fuji could be using different color filters, or different readout strategies.

      • Pancanikonpus

        i dont believe that, such small volume, why not gives to Sony to do it, cost need to justify at the end

      • nwcs

        It’s a Sony base layer with some Fuji special sauce added and probably Fuji designed data pipelines rather than the stock ones. People say sensor but the “part” is really a conglomeration of multiple parts.

      • peevee

        It is of course Sony. Maybe, MAYBE Fuji designed the board on which the chip is mounted.

    • Chaitanya

      check fuji interviews from Photokina, the sensor inside this camera is Bayer not X-Trans.

      • Neopulse

        Why would they stray from their “signature” layout style with this sensor? They did do it I think in one of their APS-C lines. But why with this one? If there’s a video (from the multitude) that explains this, please post it.

        • El Aura

          Again in one of their interviews, they said that X-Trans requires more computational power to de-mosaic, which when coupled with 50 MP (and maybe a slower read-out from this sensor then from their APS-C sensors) makes feeding the EVF/back display as well as the AF algorithms with a high enough frame rate more of a challenge.

          • Zos Xavius

            Truth

          • Neopulse

            Kind of disappointing though. They had a bigger body to work with and years to create a better way of creating that desired computational power. But if they say so, well…. gotta swallow that pill then.

          • peevee

            X-Trans has NO advantages over Bayer except marketing to art types who don’t get the technical side. It DOES NOT even eliminate moire (just reduces it a little), it is just diagonal instead of vertical and horizontal. And the similar or better level of moire reduction vs detail loss can be achieved using a Bayer sensor without AA plus a little smoothing/unsharp filter in software.

            I bet real engineers in Fuji were furious when somebody in management made them do this thing, wasting precious performance and battery life.

          • Neopulse

            Did not know it was that terrible. Wonder if there will ever be a better format than Bayer one day? Foveon doesn’t count obviously, but another. CCD for example is on it’s last years.

          • peevee

            It is not terrible, sorry if I gave that impression. But it is somewhat worse, at somewhat higher price – usual for marketing exercises.
            CCD or not CCD has nothing to do with color filter array on top of it. Bayer CFAs are installed both on top of CCDs and CMOS sensors, and BTW, there is not that much difference.

            Modified Bayer CFA, RGBW, is used by some Sony sensors, for example, IMX278 which is rumored to be installed on the upcoming Google Pixel phones. It provides very slightly better SNR (lower noise) than Bayer’s RGBG at the cost of slightly higher computations and slightly worse color differentiation. The higher compute cost is probably the reason why IMX278 does not support HDR video while the same chip with Bayer CFA (IMX258?) does.

            New sensor technologies are VERY possible, not only Foveon-like. For example, a sensor with energy-differentiated photon-counters with no CFA for pixels can add a stop of noise performance AND global shutter, which would be a revolution. But to implement something even like 16mpix, they’d need to be manufactured on modern technologies like 14nm, not the ancient 500nm, 180nm and even the very old 65nm they just started switching some of their lines.

          • Neopulse

            What I meant when I said CCD that apart from CMOS that kind of it the only other sensor style on the market (Foveon too). Once CCD is gone, chances are it will be 99% CMOS with the bayer filter array in the market only.

          • peevee

            My impression is CCD is already gone outside of industrial applications. It was used only in cheap P&S since Kodak stopped producing them in large sizes, and the cheap P&S sales almost disappeared due to phones.

          • Neopulse

            To be honest I think I’d still like to buy a high megapixel CCD sensor camera. I’ve shot with the Leica S (Kodak sensor at the time) and I just was bought by it’s out of camera look. Kodak (actually TruSense bought their sensors long ago) make the standard 40MP 33×44 sensor and also 60MP in camera platforms such as Pentax, Hasselblad and Phase One. But there are other makers like Dalsa that made for the Mamiya (now Phase One) system that also were very respected with their near infrared image capturing.
            Maybe they stop producing them yeah, but I still enjoy thoroughly the images those sensors produce.

          • Neopulse

            But very educational though your explanation. I thank you.

        • sperdynamite

          1. XTrans is garbage and fucked up a hefty share of people’s photos for no real benefit.

          2. Xtrans was only ever about reducing moire and there is less instance of moire at this resolution.

          • Neopulse

            Why did it fuck up their images if you don’t mind me asking. And yes I remember about one of the perks was to reduce moire. I remember that.

          • sperdynamite

            Search for ‘watercolor effect’ and ‘waxy skin tones’. The whole point was to eliminate moire and use non-AA filtered sensors. But the only thing that came of it was a great difficultly using standard raw processors, meanwhile other makes went without the AA filter and nobody reported a particular problem with moire.

          • Neopulse

            Will check it out. I used to own an X-E2 and several lenses. But traded them in and got myself into Sony. As I did not see anyone trying to make a strobe system compatible with the system and they lagged too much in lighting at the time 2 years ago. But even though I shot in well lit areas with manual flashes, I barely noticed that problem. One particular time in a backlit scenario, the image came out atrocious. I’ll never forget. But thought it was my fault though in a way or maybe the lens coating.

          • peevee

            Because it has larger radius of “debayering” (“de-X-transing” in this case), destroying more detail than a Bayer CFA (but also works like extra built-in noise reduction which you cannot turn off).

  • sickheadache

    My only thing is that Battery Grip. Sony A Made that same type of Grip..IT is way too small…The Firing Button needs to be at the end of the Grip..for bigger non Japanese hands. lol

    • The grip on the vertical piece is the same length as the grip on the camera.

      • sickheadache

        The Trigger Button is not. IF only they would extend that firing button up further…Like the Batter Grip for The Nikon D810 is Perfect. I have big hands…

  • Pat Mann

    Hasselblad with 1/2000 flash sync but no Biogon vs Fujifilm with a nice wide lens coming but slow flash sync only. Decisions, decisions.

    • Neopulse

      To be honest Pat, I think I’d wait and see. The Hasselblad was 1/800 for years and just this year the 1/2000 was in production. So far between Pentax and Fuji, Fuji is will win modern lens wise. But, just wait until they make adapters for it.

    • Thylmuc

      The Biogon surely is special. It’s rather sad that Zeiss does not provide the X lenses. But then, there are 24 mm and 28 mm lenses available for the Hasselblad. (via the H to X Adapter, 290 Euro). Not too bad. The Hasselblad will already have 15 lenses available upon release.
      Since there is a cooperation between Alpa and Hasselblad, it seems that Hasselblad is rather open regarding their protocols. Maybe they would be willing to provide the Information to Zeiss, so that they could come up with a Biogon variant.

    • Brennan McKissick

      But the Fuji has the capability to add LS lenses in the future or adapt legacy LS lenses. The Hasselblad will not be able to take anything except modern LS lenses. Also, the Fuji has 1/4000th shutter speed which is handy.

  • The all black finish is strictly business, the kit has a nice chunky look with the vertical grip. A couple styling touches with color accents would be nice but not really necessary.

  • Henri De Vreese

    At the same price of a Hasselblad and similar performance. I think more people will opt for the X1D. Certainly the all black kit!

    • nwcs

      It is allegedly going to be significantly less expensive than the X1D. Apparently you will get the body plus lens for the price of the X1D. But pricing has not been announced.

      • Henri De Vreese

        You are still talking about 8000 EUR for the body+ lens compared to the X1D + lens being 10.000EUR.
        Not that big of a difference for a working pro imo.
        Most people shooting hasselblads also shoot Broncolor, just a Para 222 is 7000 EUR. That’s a light modifier for a studio flash.
        MFD is not for enthousiasts (aka the people that are discussing Fuji vs Hassy based on price difference).

        • nwcs

          2000 Euros is still a lot of money.

          I think a camera like this will appeal to gear addicts as much as it does the working pro. I think we’ll see a whole new class of gear-love going on with people trying to lord it over the “full frame” people. We’ll also see some enthusiasts using it since it’s now more within their reach.

          Fuji’s system has the potential to add leaf shutter later so you’d get the best of both worlds.

          Doesn’t matter to me, though. I’m not interested in either system now that I know more about them. They don’t fit my particular needs and interests.

  • Melbar

    I can only laugh about the hype around this new “small MF class” of cameras.
    It´s a lot of money more for 20% better image quality compared to FF.
    I bet 90% who want this camera have never shoot with MF.

    • Les

      You are pulling a lot of very specific numbers out of thin air!

      By the way, what exactly is wrong with bringing new customers into the medium format market? Did you expect Fuji to aim at PhaseOne’s 2,000 customers? Why even bother if that was the case?

      The reasons for getting a medium format camera now are the same as ever. You can get the same image quality from smaller formats, but then you need to fully optimize every aspect of your technique. We’ve all seen prints where the photographer stretched a 35mm capture too far, printed too big, whatever. The image starts to fall apart.

      • Melbar

        prove my numbers wrong. .)
        i give you another number.
        in 2013 the whole medium format market was 6000-8000 cameras.
        that´s according to leica who did their research.

    • CHD

      Your same argument can be applied to buying micro 4/3 instead of APS-C…..or buying APS-C instead of FF….you get it???

      • peevee

        No. APS-C loses 1.3 stops of light compared to FF, while having lenses with the same f-number (i.e. lose 1.3 stops total).

        m43 loses 2/3 stops compared to APS-C, while having same f-number lenses (in the best case with just released Oly 25/1.2, only 1/3 stop), which are for some stupid reason MORE EXPENSIVE recently. I.e. you lose 1/3-2/3EV, while paying more.

        FF systems lose ~2/3 stop compared to this undersized non-MF (44×33), while having lenses generally 2 stops faster (i.e. WIN 1.3 stops compared to this “MF”).

        AND you get everything cheaper. What’s not to like?

        Of course for macro and supertele applications more dense sensor is better, larger size of the sensor almost does not matter. m43 and even Nikon 1 would be the best, but they have nothing above 800mm eq, and even these 800mm-eq are strictly for sunlight (f/12.6-equivalent aperture). For macro so far 20-mpix m43 sensor and Oly 60/2.8 is the best, both for density, AF and stacking (both on Oly and now even Pana cameras). Nikon 1 does not have native macro.

        • CHD

          I’m not talking about just f stops and iso perfomance. As an example the Fuji will have 16bit colour, something not currently offered in any FF camera.

          • Teemu Kustila

            Sadly it’s reported being only 14bit. Afaik.

          • CHD

            Check again…I’ve read it’s 16. Not to mention it’s just a variation of teh Sony sensor used in the new Haselblad, also 16bit.

          • peevee

            A pixel in 50mpix 44x33mm sensor does not have 16 bits of info. About the same density as 36mpix 36×24 sensor, and that one does not quite fill 14bits with info, let alone 16. And how the extra 2 bits of noise will create “different look”, even if it were not noise? All media has 8 bits per color channel anyway, not 14 or 16.

          • CHD

            It’s the same sensor as in the X1D…which also has 16bit colour depth, which helps with post processing. Anyway…my point is that there is more to bigger sensors than megapixels….there is a different look. If you don’t get it or can’t see it then no point arguing with you.

  • Mistral75

    Additional detail: the GF 120mm f/4 Macro R LM OIS WR has a minimum focusing distance of 45cm and a maximum magnification of 0.5x (macro 1:2) https://uploads.disquscdn.com/images/5af473c8149fa7c16a7fb2967dfad72b9ae8178f29a8e39648df8097dd319733.jpg

  • Mistral75
  • ZMWT

    This is best looking digital Fujifilm camera so far. Very nicely polished up, looks like properly designed camera. Compared to this, all Fuji X cameras looks like Barbie’s plastic toys.

    • CHD

      It looks nice…but my money says that when you pick it up it will have the same hollow, tinny feeling you get when you pick up any of the X cameras. I’m not saying they aren’t durable…I never had an issue with my X-Pro1, but I hated how ’empty’ it felt compared to say my M240.

  • Hubertus Bigend

    F is for film—Ah, that reminds me of what I forgot to ask the Fujifilm people at Photokina: Nice camera, but where goes the film?

  • ZMWT

    Btw, for such a wide bayonet, why they did not design it with four lens locking mechanisms, but opted for (old school) three? Considering the size of lenses and how much twist is required for a lock, Leica SL mount looks much smarter than this.

    • Brennan McKissick

      I’m sure someone much smarter than any of us has done the research to know that nothing is going to break. The SL lenses are enormous compared to anything that’ll be released for the Fuji. And the SL might as well become extinct after this latest round of upgrades anyways. It’s not even in the same category as this Fuji or the Hasselblad.

      • ZMWT

        ?!? Your answer is technically incomprehensible. There is no reason to use three locking mechanisms in such a wide circumference mount unless one wants to break the arm.

        • Brennan McKissick

          The Pentax 67 and 645 systems somehow managed to struggle through 50 years of use without breaking and I’m quite sure those mounts are larger and the lenses heavier than any Fuji will produce, so please tell me how “technically incomprehensible” my logic is.

      • fanboy fagz

        really? cause every product ever made was always researched properly and made the best it could be. not 1 product every made that was researched had flaws because it was designed properly? because in your eyes those who made it were smarter than everyone and it was researched and they deemed it to be best, although it wasnt, right?

        how narrow minded can you be?

        • Brennan McKissick

          If I could decipher what you’re trying to say I would reply.

          • Neopulse

            He does that apparently

          • fanboy fagz

            thats ok. you dont seem to be running all cylinders to understand.

          • Brennan McKissick

            Says the person who can’t type a sentence well enough for someone to understand what he/she is saying.

    • CHD

      The Leica’s mount needs to be more robust then this because they use enormous, heavy lenses. If Fuji makes these GF lenses like their XF ones, then they will be extremely light.

    • peevee

      Germans overengineer everything. It is the cause of low reliability of all of their products.

  • Lukas Dvorak

    Im thinking about one thing. When there will be viewfinder mounted, how i will use flash transmitter. For example im using profoto air remote which have to be mounted on camera. Shooting throught display is not so proctical.

    • Brennan McKissick

      There is a hotshoe on top of the finder.

      • Lukas Dvorak

        Ok super! 🙂

  • Neopulse

    Thank you!!!

  • Camaman

    IMO not much medium in these new medium format mirorless cams… Just 0.79x crop.
    Although a cool addition to the foto world..

    “GFX stands for: G is the format, F is for film, X is for the X DNA”

    Useless marketing claptrap. What film?

    “New G Mount:

    6mm deep mount”
    It is at least 26mm.
