It doesn't matter what we think - what matters is what Pentax thinks, and we can react. I am having great fun with my KP, which was their intent - I cannot think of any time I've thought about the 'accelerator' when shooting at ISO=200, nor have I ever missed a detail. For the first time since I picked up a camera over sixty years ago, I can shoot wildlife {I usually use TAv mode} without having an ISO ceiling restricting my actions.
The details that were "missed" when the accelerator was introduced were so ridiculous as to be laugh worthy.
When the D810 came out 36 MP compared to the K-5 16 MP, I looked pretty extensively at IR images. IN some places the K-5 images were better, in some place on the same image the D810 images were better. Others who were actually printing files noticed the same thing, when using independent viewer's evaluations.
24 MP compared to 36 MP doesn't always make a positive difference looking at the whole image, and by picking one area of a photograph over another you can make a case for either being better.
The whole accelerator chip discussion was nonsense from the start, and at best a lesson in how to manipulate tests to make a point. (Hint pick the one part of the photo where the photo is better without the accelerator, ignore the parts where the accelerator does better, and focus only on that.
The funny thing is, since that original completely biased test, not a thing has been added. Using the same methodology, I could have "proved" a 16 MP K-5 is better than a K-1 for IQ.
