Originally posted by Ray Pulley I have far more faith in my tests of several cameras and about 10 lenses as well as real life shooting since that time than I do in Falk's tests.
So you are claiming that your tests are as rigourous, repeatable, and well documented as Falk's?
Did you notice that his report clearly states that he verified the issue under certain conditions only?
Have you run your tests in the same conditions?
Did you notice that he wrote that the firmware update may or may have not improved the issue under different conditions?
Why are you insisting that his experiments are incompatible with your observations? They need not be (depending on the conditions present during your tests).
Originally posted by Ray Pulley I find it rather amusing that so many internet "experts" somehow know more about the performance and design of a complex camera system than those who designed and built it.
Do you realise that Falk knew more about the K-7 shutter blur issue than Pentax itself? Do you realise that Falk wrote an AF contrast algorithm that would even beat the improved K-5 contrast AF?
Yet you put "experts" into quotation marks and you are "amused"?
You cannot fault your K-5's AF. Good for you. But why ridicule a Physicist who clearly has sufficient expertise to give Pentax food for thought?
Originally posted by Ray Pulley As if Pentax waited for months and then simply issued a firmware placebo. Right.
No one said it was a placebo. The firmware update helped in certain situations. However, it has been demonstrated that the firmware update did not completely fix the AF issue.
I know a Pentax dealer who is glad that Pentax eventually managed to address the AF woes of the K-5 with the new AF optics of the K-30. Why would he, if the firmware update had put an end to all K-5 AF discussions?
Let me repeat: "Luckily, we don't need to worry anymore as the last K-5 copies are being sold now and Pentax appears to have solved the low-light AF issues for the new models."
