Surely 3dB. Liogarithmic scales work on units of 3 for a doubling. That's why a 200 ISO film is 24 DIN and a 400 ISO is 27 DIN.
No issue with that John, I quoted a previous post.

"The more bits you have the greater the magnitude between the highest and lowest light levels you can store. For every bit you double the distance between the brightest and the dimmest light level you can store. Doubling ( or halving ) the level of a signal, whether that is light or sound, is 6dB. that's why in signals it's 6dB per bit."

What is the actual range of the sensor (transducer). Having the capacity to store a "range" is fine providing you can "see" the range.

Only ask out of interest. I suppose common sense says that a manufacturer would only use complementary components.

Just for the technophiles:

Interesting times?

If Pentax go with this and it proves faster and reliable (my SDM's have been OK to date), what's the forum members thoughts if Pentax re-introduce their SDM lenses as Mk II variants.

Nikon are doing this with VR II but it could be done with AF in the case of Pentax.

If it does happen, who would upgrade and what's your thoughts on what your current pride and joy lens(s) are going to be worth?
