Wrong the focal plane shutter does not prevent dust getting on the CCD. It's the non Dslr cameras withoutremovable lenses that don't get dust on the CCD. |

So a Focal Plane Shutter doesn't cover the CCD in a dSLR the way that a Focal Plane Shutter covers the film in an SLR?
I understand the other reasons some cameras use a Focal Plane Shutter (e.g.: blooming, smearing, dark frame subtraction), but it seems to me that using a Focal Plane Shutter to cover the CCD would be a good idea. |

While it covers sensor when changing lens that doesn't prevent dust from getting inside camera, and when you take next photo shutter's airflow can blow that dust so that it lands to sensor. To prevent this "sensor/shutter compartment" should be closed airtightly meaning glass plate between shutter and lens mount. |
