I am wondering whether there is a kit for making software improvements to the Pentax K-x camera.

What I'm after is something akin to the CHDK, which is a firmware enhancement for many Canon point-and-shoot models.

  • good. :] just didn't want to presume (as a new comer) – Andrew Matthews Mar 24 '11 at 5:53
  • CHDK isn't exactly an SDK, although adding scripting capabilities is one of its cool features. I've edited the post to reflect this -- hope you don't mind! – mattdm Mar 24 '11 at 20:41
  • not at all - if it increases the chances that someone will know what I'm on about. I would be happy with something that provides programmatic access to the existing firmware. I'm not necessarily seeking to replace the firmware with anything else, I just want to automate some tasks, as is possible with CHDK. – Andrew Matthews Mar 25 '11 at 4:18
  • What tasks do you want to automate? – asalamon74 Mar 25 '11 at 7:50

I've also tried to find a CHDK-like software for Pentax, probably the best Pentax firmware hack project is Pentax Hack.

They were able to decrypt several Pentax firmwares, and modify a few things, like turning on debug mode.

Although the project supports several Pentax DSLRs, unfortunately it does not support K-x.

  • +1 That's all that I've ever found too... Mind you, I wouldn't do this on my current active camera. :) – John Cavan Mar 24 '11 at 15:58


There is a guy who named himself "shodan", putting effort into completely hacking the current Pentax DSLR firmwares...

here is the link to his github-page:
