Neither is required for a sensor cleaning, but if you choose not to leave a lens attached, please attach a body cap to keep dust from entering the camera body once it’s been cleaned.

Unfortunately, our specialist has a workload that does not allow for sensor cleanings to be done while you wait.

We do test the camera’s sensor after each cleaning. Occasionally, we will need to make multiple cleaning passes, but the customer is not charged for the additional materials/time used.

Although we only see this roughly 2-3% of the time, it is possible that dust/debris has worked its way under a low-pass filter, or via another means, and would need to be handled by the camera manufacturer as a repair. We cannot tell whether this is the case until we have completed the sensor cleaning.

That most likely means that dust/debris is on the mirror. There are other potential culprits, but the mirror is most likely. If we find this to be the case, we will attempt to clean the mirror, but cannot guarantee that debris on the mirror can be removed.

We do not disassemble any lenses in-store for cleaning. A small amount of dust inside a lens is very typical and rarely causes issues in images. We recommend that you occasionally clean the front lens element, and we do sell cleaning supplies in our store. We also recommend using protective filters on your lenses.

We do not ship the camera back to you. It must be picked up in-store.
