Canon C100 Mark II Sensor Cleaning & Full Service
Video cameras like the Canon C100 Mark II pull dust into their cooling system by design. Our full service cleans the sensor, low-pass filter and fans at a fixed €650.
Symptom checklist
- Dust spots visible in footage
- Dirty sensor or low-pass filter
- Ventilation grilles clogged with dust
- Cooling fan less effective than it used to be
If you shoot regularly with a Cinema EOS body, sooner or later a Canon C100 sensor cleaning stops being optional: the C100 Mark II cools its electronics with a fan, and that same airflow steadily pulls dust into the camera. The fix is straightforward — we perform a complete cleaning and service at a fixed price of €650, with free diagnosis and a 6-month warranty.
The symptoms
Dust build-up in a video camera shows itself in two ways:
- Optically: dust spots and marks appearing in your footage, coming from a dirty sensor or low-pass filter.
- Thermally: ventilation grilles visibly clogged with dust, and a cooling system that has to work harder because its airflow is restricted.
The customer in this case contacted us simply to have the inside of her Canon C100 cleaned — a sensible piece of preventive maintenance for a working video camera.
What causes it
This is not a defect; it is how the camera is designed to survive. Because the C100 Mark II is built for video, its electronics and sensor heat up considerably during use. To deal with that heat there is a cooling fan — and as the fan moves air, dust comes in with it. Over time the dust settles on the ventilation grilles and clogs them, reducing the cooling system's efficiency, and finds its way onto optical surfaces like the sensor and the low-pass filter. Every fan-cooled camera accumulates dust this way; the only question is how often it gets cleaned out.
Can you fix it yourself?
You can keep the exterior grilles free of loose dust and gently blow the exposed sensor area with a hand blower. But the dust that matters — inside the ventilation path, on the fans, and on the low-pass filter — is only reachable by opening the camera. On a professional video body that is not a job to improvise: the value of a proper service is that everything is cleaned and checked in a single, controlled intervention.
How we repair it
A customer sent us her Canon C100 Mark II for an internal clean. Our technicians carried out the complete cleaning and service: sensor, low-pass filter, cooling fans, and a general check of the whole camera. During that inspection they also noticed that the external jack had damaged pins — these were restored as part of the work, which is exactly why a full service beats a quick clean: problems get caught while the camera is already open.
The camera went back to its owner clean, properly cooled and working correctly, with our final function check included. We service and repair the rest of the Canon range too — see our Canon repairs.

Frequently asked questions
Why does the Canon C100 Mark II collect so much dust inside?
It is a video camera, so the electronics and sensor run hot and a fan cools them. That airflow constantly pulls dust in, which clogs the ventilation grilles and reduces cooling efficiency over time.
What does a Canon C100 sensor cleaning service include?
Our full service covers the sensor, the low-pass filter, the cooling fans and a general check of the camera — everything is cleaned and verified in one intervention.
How much does a Canon C100 Mark II full service cost?
We charge a fixed €650 for the complete cleaning and service, with the final function check included. Diagnosis is free.
Can I clean the C100 sensor and fans myself?
The exposed part of the sensor can be blown gently with a blower, but the low-pass filter and the fan/ventilation system require opening the camera — that part is workshop territory.
