Having dust on the sensor can go unnoticed pretty easily when shooting close to wide open. I would recommend tilting up to the sky when shooting outdoors and stopping down to a 22 or setting up a brightly lit white card when shooting indoors and stopping down as far as you can. Check on a large monitor for sensor dust.
What are people using to clean the sensor? Is Red recommending anything in particular?
Is this a pretty good solution?
What other procedures are people developing for checking the gate after a shot is circled as far as insuring everything is recorded properly and "in the can"?
