How often should we expect to clean the sensor. 3,500 or so frames and several spots have appeared. Didn't seem to have this issue w/ my 5dIII. It took a long time to get spots on the sensor.

I clean my sensor fairly often. My APS-C cameras only very rarely get dust, but my 1D X attracts it like a Swiffer. Rocket Blower, Visible Dust Arctic Butterfly and a Sensor Loupe are all I've needed (I have Sensor Stamps just in case).
