Blackmagic Announces 80MP 60fps Camera

BusinessWire: Blackmagic Design announces URSA Mini Pro 12K digital film camera with a 12,288 x 6,480 12K Super 35 image sensor, 14 stops of DR and 60 fps frame rate in 12K at 80MP per frame.

"The Blackmagic URSA Mini Pro 12K features a revolutionary new sensor with a native resolution of 12,288 x 6480, which is an incredible 80 megapixels per frame. The Super 35 sensor has a superb 14 stops of dynamic range and a native ISO of 800. The new 12K sensor has equal amounts of red, green and blue pixels and is optimized for images at multiple resolutions. Customers can shoot 12K at 60 fps or use in-sensor scaling to allow 8K or 4K RAW at up to 110 fps without cropping or changing their field of view."

The brand ambassador John Brawley shares his knowledge in cinematographers mailing list:
  • Brand new sensor, 3 years in the making.
  • 79 MP.
  • Native 800 iso.
  • 14 stops (that’s probably a bit conservative, they haven’t been able to properly check it because the models are based on Bayer sensors...:-)
  • It’s not Bayer, but it has a very small pixel pitch of 2.2 microns. (Alexa is 8)
  • Instead of Bayer 2x2 grid of GRBG it has a 6x6 grid. 6G, 6B and 6R plus 18 W pixels.
  • The W are clear or “white” pixels. This overcomes the reduced sensitivity issue of a 2.2 micron pitch.


The sensors are shown in Blackmagic presentation video:


The new sensor's readout speed is

12K (full FOV) : ~15.5ms
8K/4K (full FOV) : ~8.5ms*
6K crop : ~7.8ms
4K crop : ~4.25ms*

*Blackmagic hopes to improve this slightly in an update

Thanks to PF and others for the pointer!

    2. It is not Canon

  3. 14 stops within 2.2 µm pitch could only be reached in rolling shutter mode... Or is it a GS stacked pixel?

    1. Rolling shutter. Full sensor readout is 16ms.
