Pentax has just posted a firmware update for the Pentax K-5 II and K-5 IIs on the Japanese support site. Firmware version 1.01 fixes stability bugs and adds an option allowing you to adjust the contrast of the rear LCD display.
User reports suggest that this firmware corrects an issue which caused the K-5 II to sometimes freeze in HDR mode.
Quick download links:
Follow these instructions to update your K-5 II's firmware:
- Download the firmware ZIP file corresponding to your camera
- Extract the file to a folder of your choosing
- Locate the extracted .BIN file and copy it to the root (top) of a formatted SD card
- Insert the card into your camera and ensure it is fully charged
- Turn the camera power on while pressing the MENU button
- Select "Yes"at the firmware prompt
- Once the screen displays "Complete", turn off your camera
- Power your camera back on and resume normal use
- In order to verify that the firmware update was successful, hold the menu button while powering your camera on. The screen should indicate version 1.01. You should then power off your camera and resume normal use.

@SkilakDeZoo. Nope, the programming is quite different.
I can't imagine that the operating system program would let you install the "wrong" firmware even if you tried.
If K-5II is based almost on the identical components as K-5, would it be possible to use that update on K-5? Just out of curiosity.
Thank you very much for this ... yes as manishved has mentioned this was an issue.Great stuff.
@manishved and it was perfectly fine after that ? mine doesn't seem to resolve itself and it only started occurring after i updated :/
Yes, I faced this issue a few times with the K-5 IIs and had to power off and back on a few times.
> Problem with changing mode (between auto, p mode, shutter priority mode and Tav mode) it all shows as aperture priority. Anyone else having the same problem ?

Great tip.
Thanks much!
LfLee, it's available on Pentax jp you can find the link on the latest news from dpreview com
Those likes point directly to Pentax's site. If you remove the filename, you will see the page where the firmwares are posted.
I can't find the firmware update download link from Pentax USA. I know PF provided the firmware here but would like to download it directly from Pentax website. Can you provide the page to the firmware?
Mind blowing upgrade!
I am amzed by this gesture. thank you!
Thank you for letting us know, without the forum I probably never would have known.
@ravula i doubt the K5II will ever get focus peaking because i dont think the processor supports it. Plus, FP makes the K30 attractive so it would hurt sales to add it to the K5II as well.
Thanks,
Wow, support for a product without promising your first born or pulling teeth, just 2 more reasons to love Pentax and its Forums.
Keep it up and you get extremely loyal customers, the "goin ta have to pry my Pentax from my cold dead hands" type.
Thanks again
BMcN.
no focus peaking?
Done...will test it tomorrow!
Whoa. LCD contrast control :D
I wonder what else they can add next.. if there's any.
LCD contrast control! That is exactly what I want in my K-5...
Seems to fix the HDR lockup bug.
That was pretty easy. Updated without any problem. Thank you for the tip.
