The camera module is smaller than that of the SO905iCS. Its dimensions are about 12 x 12 x 6mm. By simple arithmetic, this is less than 0.1% of the volume of the main body. This is probably because the W61CA does not have an optical zoom function, although it is equipped with an autofocus function.

The image sensor has an effective pixel count of 5.15 megapixels and is about 6mm diagonally. This implies that it is a 1/3.2-inch CMOS sensor with a pixel pitch of 1.7μm, like the one in the SO905iCS. This time, we could not identify the manufacturers of the sensor and the camera module.
