Older DC adapters for K5 and K7 will do fine too. Try Ebay

Thanks guys - went to ebay, saved $80 off B&H (sort of)

It's my understanding from past posts that all the AC adapters (at least from the K10D on) are interchangeable. For the bodies that don't have a jack there is an adapter that replaces the battery.

There are also 3rd party adapters.

There's even a name for the plug: Hirose MQ172-3SA-CV(50)

If you're handy with a soldering iron and can read schematics, you might want to check this out: DIY AC Adapter for The Pentax K10D and K20D | The Roaming Drone I use 2 of these daily to shoot hummingbirds, dawn to dusk, powered by 12v batteries for UPSs.

Since I don't use one very often, I have found this one seems to work fine. The only Negative review was that it didn't charge the battery in the camera which is not how Pentax works anyway. $11.91 on Amazon.

The question that arises now is: "Do you trust a no-name manufacturer sold by Amazon to create a product that surely won't damage your camera?"

Amazon's track record in selling counterfeit and in some cases really dangerous products would make me wary of such an offering.

I agree on this solution. I had a friend make two of these for me several years ago and they are still working perfectly when I do long exposure work.

Are you using this to power the K-1 with 12vdc?
