For months now on RED User I've described my RED cameras as being "DSLR on steroids". From the mount backward the technology definitely parallels that of a DSLR. Most DSLR use CMOS sensors and shoot at 1 to 3fps, with some shooting as many as 10-12fps. You can shoot 1 to 75fps on RED One. A description of a RED One camera as a DSLR that shoots 1 to 75fps is pretty close.
I have a 20D and XTi, and thought at one point of buying a MkIII - then it dawned on me that short bursts and adjusted shutter speeds on my RED One cameras essentially relieved me from spending $6.5k on a MkIII body.
In overall technology pedigree, from the mount backward, RED One is closely related to a DSLR (sensor, etc.), relatively related to a TV/video camera (electronic circuits, audio), and bears almost no technology pedigree to a film camera. From the mount forward RED One can resemble a film camera, TV/video camera, or a DSLR depending on what lens configuration you use.
In operation, RED One can be used in an all manual film-style workflow with handheld light meters and measuring tapes, or in a hybrid WYSIWYG TV/video/DSLR workflow using the camera's electronics to aid in focus and exposure.
It's really a flexible camera system - and yes, the still frames from it seriously rock.
BTW - nice frames grabs Jim. They look like they were shot from the Bellagio. I was based in Las Vegas for three years - shot the Bellagio fountain shows many times - very magical.
