Thanks, but I'm fully aware what dof means :). I don't understand why typical 2K/HD video cameras couldn't do small depth of field. Nikon D90 could do small dep

  It's more than just aperture, though. F/2 on a wide-angle lens like the iPhone won't give you the same impact as F/2 on a telephoto. Most low-cost HD video cameras have severely compromised lenses, and professional cameras tend to have extremely expensive lenses. Red solved the problem by tapping into the Canon/Nikon lens base.

    It's not about field of view (a f/2.0 wide angle and telephoto shot both have the same DOF in terms of actual length - telephoto just appears to have a shallower DOF since the image is cropped.) DOF is actually a physical property of sensor size and aperture size. http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm http://www.cambridgeincolour.com/tutorials/digital-camera-se...

  They can, its just the cheap HD cameras had tiny sensors. The smaller the sensor, deeper the depth of field (therefore less blurry) The canon 5d mkii has a bigger sensor that the RED one, and therefore is capable of blurry DoF. http://www.bobatkins.com/photography/tutorials/crop_sensor_cameras_and_lenses.html http://www.bobatkins.com/photography/tutorials/crop_sensor_c...
