“rolling shutter” on HVX-300?

[Dan Brockett]

I cannot think of a professional video camera that uses CMOS imagers than contains a global shutter. Do you know of one?

Depends how “professional” is classified. Broadcast style ENG cameras with CMOS chips don’t have this feature.
Dalsa has a high speed series “Genie” camera with global shutter on a CMOS chip.
It can be done, it’s up to the manufacturer to specify the technology for use.
I believe that a rolling shutter is technically easier and uses a bit less power than Global shutter on CMOS chips. This ultimately means lower noise levels off the chip.
Many “machine vision” cameras used in manufacturing are CMOS with global shutter.

I agree, it could be done but so far, nobody is stepping up to the plate, not even RED. Eventually they will have to implement global shutters but probably not for a while.

Hi,

As far as I know, the Arri D21 is Global.

that would be a mechanical shutter in the case of the Arri D21- just like a Arri film camera.
