Update: SonyAlphaRumors is now reporting that this new Sony camera will not shoot 8K and will top out at 4K 120P. Along with this correction, they are reporting that the FX3 will use CFExpress type A and will retail at €3795.
It looks like Sony is going after both Blackmagic Designs and Canon with their next cinema camera, the Sony FX3 (ILME-FX3). It appears to be an E-mount cinema camera with impressive known specs.
According to SonyAlphaRumors the camera will have the following capabilities, and much more.
“New 8K ILME VIDEO CAM! It Can Shoot UHD 8K, Oversampled DCI 4K, HFR UHD 4K.”
The exact announcement date is unknown at this time, but I'm sure the leaks will be flowing freely over the next little while.
