Sony | α | α9 High resolution full-frame 4K


α9 is capable of recording high-resolution full-frame 4K movies with wide dynamic range. Full pixel readout with no pixel binning makes it possible to condense approximately 2.4 times* the amount of data required for 4K (the equivalent of the amount of data required for 6K) into 3840 x 2160 4K output. This oversampling process plus fullframe pixel readout without binning results in the highest possible 4K movie image quality.

* 24p recording. Approx. 1.6 times for 30p recording.

  1. I think a lot of you is forgetting the key about this camera……..

    When Sony introduced the A7 it was a clear hybrid, a stills camera made to shoot video as well.

    Then they introduced the A7s and A7s II, both suited very very well for video and at least b-cam for the FS series.

    Now… if the A9 can produce this, set aside what we all would like it to be able to, then imagine what we will see once Sony break the A9s to us… :O

  2. the 1 thing i don't get about 4k is that sometimes the footage at the rim of objects or subjects looks like its moving

  3. Truly a technical marvel of a camera!

    HOWEVER, no SLog and no weather sealing means no buy for my use. It would be a good landscape & (maybe) wildlife camera yet no pro weather sealing means I can't leave my A9 out in the same conditions as a 1dx. No log and small bit rate means for my particular video uses.

    Still a VERY impressive camera which has unfortunately, been held back by the marketing department. Still wouldn't mind one though!

  4. Imagine a Full frame Iphone sensor with 35mm Detachable Lens, What a great concept. A new breed, a crossover, a game changer. FYI in Sony Experia, this Exmor RS Sensor capable of producing 960 FPS Super Slow Mo Video. Imagine what the next A9s can do.

  5. The new a9 looks great, my only disapoint feature is a flip screen for Vlogging. Sony please on the next build have this feature, build a VLogging camera.

  6. alll you have to do is wait 5 months after this camera is released for the MK2 version to come out and this one will only be $499

  7. Beautiful footage. Imagine that A9 chip on the new Sony Venice Digital Cinema system at 60 I-frames/ps, XAVC , 4:2:2 and with a Cooke, or Zeiss CP Prime lens!
