I finally got around to upgrading my K10D firmware to 1.31. I got a nice surprise after I did!
I was messing around with some scripting for the K10D that I found (no I couldn't get it to work - I'm guessing it's because I'm in debug mode) and had the Tamron 75-300LD macro lens on and it was struggling with auto focus (going from one extreme to the other) in the dim light in the living room. After I got board with the scripting I decided I would try the new firmware.
I downloaded the self-extracting exe file and copied the bin file to my SD card.
I held down the menu button and applied power to the camera.
The install process went without problems so I formatted the SD card and restarted the camera with the menu button pressed to verify the firmware upgraded. Yup, 1.31.00.19 showed up on the display.
The camera still was in debug mode so upgrading the firmware didn't remove debug mode. That's kind of cool except I was hoping it would turn off debug mode since I have misplaced my USB cable. :/
Oh well, it's nice to know that debug still works with the latest firmware.
On to my nice surprise. I was testing out the camera to make sure it was all still working after I had messed with it so much earlier with scripting and testing (my auto focus points were jacked) and I noticed that instead of the 75-300 going from one focus extreme to the other to find an object it snapped right into focus. Wow, was it a coincidence?
I purposely close focused on my subject and pressed the shutter button half way. Where before the Tamron would go completely to focus extreme before focusing in the opposite direction and finally snapping on the subject, it now did about 3 quick (comparatively) short jumps into focus. I tried it a couple of times in dim light and in brighter light and the focusing definitely was shorter because it did not travel to the focus extremes. The focusing still went awry in very low light but that is to be expected.
So along with a few others I think Pentax sneaked in some focus code into the latest firmware.
