Why do new K-5 cameras have old firmware?

I just got my K-5 last night. It has serial number 401XXXX. It has firmware 1.01.

Why is it not the most recent firmware?


BTW the camera feels great. It handles much better than my K-10 and K-20. I can't wait to grab some images! Too hot here today in L.A. to go outside.

Thanks,
Lance

It seems most new K-5 indeed have 1.01:

I am going to go out on a limb here and suggest that the later version of the software change the camera's responses in the testing cycle in manufacturing. So rather than update the test software also, they go with the version that matches the automatic test system that is already setup.

Just a guess....

Maybe, but if so how do they regression test the hardware against the updates?

The AF and the memory addressing are a bit different now compared to 1.01.

IT wouldn't surprise me if the firmware were loaded on the chip when the memory chip was made., and long before the camera is assembled making a relatively long pipeline

Hmmm.... not so with my K-5

My K-5 with prefix 38 had the 1.10 firmware. Why the variation I wonder... doesn't seem to be any logical
firmware protocol - if you take the serials into account? Nogster

Hi
My hunch would be the FW is imbedded in the main Board which is supplied to PENTAX by a third party and will not show a more recent FW version number until a new batch is delivered. Could this make sense ?
