There is a step missing between step 19 and step 20. The guide doesn't mention disconnecting the yellow and blue connectors at the top that are connected to the top control panel (with shutter release, power button, and zoom ring), then to remove the top control panel. The blue connector pulls out toward the top (use a small flat screwdriver) and the yellow connector pulls out toward the side (use an even smaller flat screwdriver). There is a small piece of plastic that holds the top control panel to the aluminum frame.

And how is the sensor accessed? At the top, it says this enables you to access the zoom assembly, but from these instructions and pics, it appears the sensor is internal to the zoom assembly. Is it actually possible to access the sensor and clean it?

CCxx - Contestar

Exactly, the title offers the access to the sensor to clean it, yet we only get the instructions to replace the entire zoom lens which comes with the sensor assembled. There are no further steps on how to disassemble the lens unit to get to the sensor itself. By the way, the article refers to the sensor as "CCD", however this camera uses BSI-CMOS sensor (not CCD, which is a different technology).

The sensor is behind the metal plate held by 3 screws on the rear of the lens assy. Remove the screws to access the sensor and the IR filter. Is is very unlikely that dust has entered here because it is sealed on the inside by a rubber gasket and clamped on the other side. Mine had dust below the IR filter that was blown out by extending the lens (with the lens assy removed) There are several openings around the lens that allow air to enter and dust to exit. The 3 screws on the sensor plate must be torqued well to make the camera focus at infinity with the zoom at minimum. (Found out the hard way) <grin>
