Err, nope. But we are mixing two things, and that's my fault - I quoted the speed of the AA filter on the K3,.. but was referring to the SR on the K5 IIs
I'll chase up the data on the K5 IIs Sensor Shift.
Anywho, my original point was, that SR in video was swapped from Sensor Shift on the K5 series, to software based Jello-wobbling SR on the K-01 and K3 (and now the 645Z) because, as was reported in an interview with one of the Pentax Japan reps, that was to stop the sensor shake noise from getting on to the video's audio track.
If the sensor still has to lift in to place, and the Sensor Shift mechanism is what keeps it ion place, then the whole noise reduction reason for the change is just a cover for doing something wrong.
In the case of the K-01, the logic for making the change to software SR is even more flawed, as it only records audio at 32kHz.
In K3, K-01 and 645Z, the 'premium', 'video hero' and 'professional' models in the range, software SR is a mistake.
