    Will be interested in the AF improvements.

    12 MP is all I need.

    Admin: any word on FPS for stills? Cannot find above nor at SAR…

    • No idea – I will look online.

    • It will be low probably, not much different from what you get with the A7/R. The small body chosen by Sony made them sacrifice a proper shutter in the two previous camera, as this one seems to share the same form factor I doubt the fps is going to be much different unless they had a break through in offering a new compact and durable shutter tech, which seems a bit unlikely.

      And it seems that there is no AF improvement, people would love a A7-type of camera with the A6000 type of AF improvement, but it seems that it doesn’t have that.

      • KT

        The lack of AF improvement has been a let down for many. I wouldn’t be surprised if in the near-future, they used the same 12 MP sensor in an Alpha 99-type body, this time with properly fast AF and decent FPS

    • Lars Steenhoff

      Continuous shooting: Max. 2.5fps, Speed Priority Continuous shooting: Max. 5.0fps

      • KT

        I’m quite puzzled by that Max 2.5 FPS from a 12 MP sensor in a mirrorless camera, I would have expected 10-12 FPS from a sensor like that. Second, what is Speed Priority Cont. Shooting? Does that mean no AF and shutter above 1/500? How do they go from 2.5 to 5.0, just curious.

        • Lars Steenhoff

          my guess is that priority would go to the shutter for the 5 frames mode and to the focus for the 2.5 frames

      • Kynikos

        Thanks Mr. Steenhoff.

    • g16

      I still think it is too low for today still camera when you need to crop, but I can see that a7s is not design only for still.

      • Kynikos

        Not everyone needs to crop.

  • Paul

    Interesting move by Sony. I’m glad someone is releasing a camera with a sensor like this.

  • Seriously impressive offering. Proper time code and many video settings available on dedicated video. Now to see the price level, and hopefully more lens releases to support this system.

  • Global

    Wow, 12mp D7S = 12mp D700S. True heir to the D700, anyone?

    Now if only Sony would focus a little bit more on lenses… streamline their menu system, and put a couple more bells and whistles on this proper full frame to make a photographers dream.

    • Nikon

      I can’t help but feel that Nikon is leaving a sizable portion of the future market out of their current brand line. The early adopters to new formats and technically have time and time again proven to be decisive in forming market leaders. Nikon and Canon are giving away the mirrorless category to Sony, Olympus and Fujifilm while slashing a hole through their bellies right in the middle of their line ups at the semi-pro APS-C and Fullframe bodies. Its very bizarre.

      The Df was always a backwards looking bandaid. Nikon needs a mirrorless Df-400 and a mirrorless Df-700 with free excellent adapters with each body to preserve the legacy of the F-mount, asap. They can keep Nikon1 as the apex of P&S. Did Canon give up?

  • Guy With-camera

    This will PERFECTLY compliment my D800. You can bitch about the 12 megapixels…..but man d4s iso quality with 120fps 720p at under 2k?

    • Global

      I don’t think anyone is complaining about 12mp. Sure, 16mp or 18mp is nice these days.. but I think what you know, as well as what I know (as well as what Sony knows) is that there is a HUGE demand for a super clean high-ISO body. And Nikon’s Df is so damn expensive, so dang intentionally crippled by a backwards thinking Nikon, it doesn’t even count.

      Gotta love what Sony is doing here. Makes you wonder if they are going to go for a 36mp or more for a Sony A8X. Then they’ll have an A7S as the true heir to the Nikon D700 and an A8 as an heir or match to the Nikon D800.

      • Jeff

        I’ll never understand why people think the Df is expensive.
        It’s the D700 of 2013/2014.
        Half the price of the flagship camera with the same sensor.
        No video, but not everyone needs it, and the D700 doesn’t do video.
        Keep complaining online instead of working.

        • sperdynamite

          Uh worse battery life than D700, worse AF, and retro ergonomics that make what people like about retro (good simple design) into what people hate about modern design (over complication). The D610s low light is not ‘that’ much worse than the Df, which is completely in the realm of more than good enough these days. Considering that it’s more of a lark than a professional tool, it’s too expensive. For $1999 I would have considered buying one, but on the same token, my D600 experience has left me soured with Nikon as a company. I’m gonna keep my film era gear and sell my digital.

      • g16

        Don’t you know your dream has came true months ago with a Sony a7R

    • fjfjjj

      D4s ISO quality? Wat

  • newoldmate

    Amazing. I can only imagine what sony will produce in a years time. The best part is it puts even more pressure on the other manufacturers. Lets just hope its not more expensive than the other 7’s. It should be equal or a bit less really, considering the requirement for external recording. A good rrp will put serious pressure on the GH4 and being FF just makes it so much more appealing. I dont think anyone would have predicted it would be sony leading the charge into compact full frame territory, let alone leading the charge alone. It really looked like Fuji would be the first, but they got a bit carried away with their x series, and Nikon.. Lol. Exciting times!

  • preston

    Wow, was not expecting this to be an A mount camera! So your A7s and A7r have a different lens mount. Ridiculous.

    • kassim

      E mount is part of Alpha brand name. This camera is an E mount camera btw.

      • preston

        In the key specifications it says “a mount system. .”, which is what they called their dslr mount. I see now in the detailed specs it says Sony Alpha E mount, which makes a lot more sense. Shouldn’t comment so late at night. .

        • g16

          In the video shows the camera comes with E mount.

  • johnny

    How about RF compatibility? I guess the red shift will be gone, but the smearing effect?

    • kassim

      Smearing is software related I think.

      • hexx

        smearing is not software related

        • kassim


  • Toys

    Yet another toy with speed compromises, and probably other problems on top (usage with wide angles, shutter shock, reflections…). Or does this deal with the problems other than speed? Only time will tell.

    • AlwaysLikedAToy

      This is yet another technological exercise, probably useless in real life. The plus is, if one is dumb enough to buy a top M43, one can as well buy this instead.
      This toy will put more pressure on M43, which are slightly better engineered, but have suffered from inflated prices so far.

      • Andrzej Lukowiec

        Well, I’m into buying M43. And I am prepared to pay premium for better engineering. Went from 43 to APS-C and now FF. When comparing (I am not a PRO), I do prefer Oly’s rendering and colours to strange greenish/yellowish cast of N… And, why on earth, I have to carry a tons of equipment when can have the same in much smaller package? Am I dumb? For you probably yes. But do not care. Because… you are nobody. Another anonymous troll 😀

        • M43IsForSukkerz

          I hate to break it to you, but equivalent lenses are not smaller. Are you dumb? Sure. Are you a poor rep for Olympus? Perhaps.

          • Andrzej Lukowiec

            And another anonymous… nobody. I am not. You are 😀

          • Equivalent

            This pic shows that you know squat about physics and equivalences, like all M43 reps and hapless fans.

          • Andrzej Lukowiec

            Equivalent is something that is essentially the same or equal to something else… Change you nick again. To Troll

          • NerdBuster

            You are nobody? You sure don’t know your physics…

          • g16

            I don’t think this Sony a7s with a lenses will be much bigger than m43.

            But hey, are you really a doctor? and your profile picture doesn’t look like you are 49 years old.

          • Andrzej Lukowiec

            Will be slightly smaller than proper DSLR’s. As the body is smaller.
            Well, no. I am not. But at least I’m not hiding using stupid nicknames…
            And my picture is from yesteryear. And I am not 49 yet… Will be in 2 weeks 🙁

          • G

            Wow, come down and take your med dude. It just my way to get your attention that you did post your email alone with the picture.

            But from your reply I can see that you’re a douche…bag. Maybe you wanna be famous or something.

            And don’t try to act tough since we will not meet in person anyway…it’s just annoying.

          • Andrzej Lukowiec

            And another one… epidemy 😉

        • Equivalent

          I hate to break this to you, but equivalent lenses are the same size. You are left with inferior sensor and higher prices, have fun with M43.

          If you are dumb, you ask? You can answer that yourself.

          • Andrzej Lukowiec

            Already answered. You must be blind… or cannot read? Or simply do not understand plain English… Doctor’s advice: try to cure your… legs? As for your brain is way too late 😉

          • Dpablo unfiltered

            I have learned so much from reading this conversation!

  • TinusVerdino

    Great but we need modern codecs for 4k, unstreamable.

  • Al

    Next year Hasselblad will repackage this camera and call it something like … The Nebular

  • Les

    As a video camera it has a obvious shortcomings: a tiny battery and Memory Stick (which can’t do 4k internally).
    You need to use an external recorder and battery pack to do serious work, which negates the small-size advantage. The wires will get in the way of Steadicam work as well.
    I see this thing purely as a “B-Cam.” Useful for low-light, and some specialized shots, but quite fussy overall.

  • Nacho

    Wath is the chepest recorder capable of this resolucion??

    • Les

      Atomos just announced a 4K recorder. Not sure of the price, but their 2K recorders are well under a thousand dollars/euros.

  • fjfjjj

    Ready for D710 dust spots.

  • Clint

    I could care less about the stratospheric ISO capabilities…the interesting thing is the dynamic range the sensor offers.

  • camaman

    Is it really 4k capable with an external recording unit?
    That will exclude many people from buying it.

    Also I cant wait for them to show us how much better high iso is compared to reduced 36MP file…
    My guess is none. Only on 12800 and beyond maybe…

    So NO 4k out of the box, no IBIS, sensor that has to limited resolution for any cropping, no PDAF, probably a thick AA filter.

    I would rather wanted a 36MP camera with stronger CPU to make good pixel merging and sRAW for those times that i dont neew big megapixels…

    This is just a proof of concept IMO. Hardly easily usable to full potential in real life without lots of preplaning and extra accessories
