Default K-3 II Question

The K-3 II webpage states that the camera uses a "AA Filter-less APS-C CMOS sensor", yet for dust removal, it says that it uses "ultrasonic vibration to low pass filter".

So, what's shaking?

The sensor. The AA filter can be simulated by shifting the sensor, so it seems reasonable to infer they are talking about moving the sensor.

So when they say "ultrasonic vibration to low pass filter", they mean "ultrasonic vibration to image sensor"?

I'll buy that, but it doesn't read that way.

An interesting question, to which I don't know the answer to. I've always been under the assumption that there's some sort of filter because the reds are well controlled and I don't think the camera is sensitive to IR. It just doesn't have the type of filter that controls moire.

I have a camera that shakes the sensor for dust removal, but the K3 is different.

So it's a good question.
