Arri Alexa XT.  System menu reads 68 hours of use, but I'm sure it is higher.  I'm checking with Arri about this.  Purchased the camera from Arri's used department a little over a year ago.  Comes with viewfinder, 3 xr capture cards and xr card reader.  Has open gate and 120 slow-motion capture.  Captures internally on the xr cards to Arri raw or prores.
