K-1 Battery Issue

I don't think this is a particular issue to just my K-1, because

a) This also happens with my O-GPS 1 when turned off, and others have had this happen with theirs, too.
b) Others have confirmed that this happens with their K-1 as well, and only if GPS is enabled.
c) And yes, it happens with any of my batteries.

It is curious, though, that not all K-1 units show this issue. Mine is a K-1 II, so I assume it's of a later production date, meaning it's not just an issue with early builds of the K-1.

Still, this is not the best thread to analyse this further. There's another one here, though that focuses on the O-GPS 1: O-GPS 1 Drains Battery When Off?: Pentax SLR Talk Forum: Digital Photography Review

Didn't find a related one on this forum, though, hence why I added myself to this thread, sorry.

Do you have GPS enabled in your K-1 all the time? Only if it is, some people see a slow drain on the batteries.

K-1 Battery Issue

The same symptom just happened to me - had the Battery in the K-1 for about 4 weeks without using the K-1: The charger has its green LED blinking.

To add to this - Any battery in the K-1 keeps draining within a few weeks to empty. I have never had this happen with my K-20D, K-5 or K-3 models. I still interchange the batteries between the models, but only the K-1 drains the batteries constantly when I leave them in the camera, which is fully turned off, of course.

I find this disturbing as it risks damaging the batteries by causing a deep discharge. Does the manual explicitly warn against this (while it didn't with the older models)? Or do I have a defective K-1?

Resurrecting Pentax firmware hacking

I can confirm that while I can enter the Debug mode in my K-1 Mk II, using the Lens features has no effect, just like with my K-3. Only the K-5's the Lens functions work for me (meaning I know how to use them).

Bootcoder clearly sounds frustrated. Sure, he's doing all the work, but that alone should not cause his reactions here. Something else seems to be bothering him, and it would be nice if he would speak up about that, in case we can do something about it.

So, no one actually knows the answer to the topic's question, i.e. how to enable Debug Mode on a K-1 II? I came here for that answer.

(Beholder3 - no, your linked solution does not appear to work on a K-1 II, not in my attempts, anyway)

Tried that on my K-1 II - with door open and holding the Menu button: When then turning it on, the display remains black, same as if I had no files on the SD card. Tried both hex sequences. (And yes, I know how to use a hex editor, I wrote more than one myself ;) )

I guess the file names (and/or hex codes) have changed for the K-1 II again. Anyone know them?

Lens release button replacement

Borrelli, thank you for detailing the disassembly in the other thread. Though, it's a bummer that this requires removal of the top and fronts as well - I don't like working with glued-on parts, because re-attaching them after removal is never working well for me. I have no idea where to find the proper glues here in Germany. I used to try several glues I got at hobby places (where they sell self-assembly miniature planes etc.), but nothing worked reliably. I may just save me all the hassle and send it in, though 90€ is a high price when a complete body is now sold used for less than 250€.

But enough of my whining. I know what my options are now. And it's now also clear that the C ring ("circlip") from uscamera is a plastic piece, more likely to break in the future again. Finding or constructing one from metal might be the smarter idea for anyone going down the DIY path.

Rick_B's foam solution post is here, BTW: https://www.pentaxforums.com/forums/115-pentax-k-5/189715-lens-release-button...ml#post2967996. It assumes that you still have (or purchase from uscamera, see http://uscamera.com/77240-a107.htm) the original button part, while you won't need the circlip nor the rubbery cone for his solution, if I understand it correctly. It's similar to gluing the cone to the button and to the camera body, but less messy, I suspect.

Lens release button replacement

As I'm in Germany, buying the parts (with rather expensive shipping of $18) adds up to half of what I'd have to pay for a professional replacement by Foto Maerz in Germany. So I'll wait for someone else to report success with these parts before I decide whether to go that route or rather have the pros do it (fortunately, I still have a K20D and a K3 to work with).

Oh, and the service in Germany informed me that the replacement button would now be using a metal instead of a plastic part, making it less likely to come off again in the future.

I also suspect that this new C ring part goes at the end of the pin, i.e. inside the camera frame, meaning we'd have to disassemble it. I wonder if anyone who repaired this piece also did open the camera case in order to put a generic C ring onto the pin's end that way, instead of using glue on the cone shaped part? I could not find any message on this board that confirmed this, though.

So, if anyone has tried this with a generic C ring or this new C ring part, let us all know here, please!

I, too, just lost the button on my K-5. I checked the USCamera site (Pentax Genuine K5 Replacement Spare Parts | uscamera.com) and see that they now list also a "K5 Lens Lock Button Retaining Clip".

Previous posts here only mentioned the other two parts, and suggested that they'd have to be secured with a bit of glue, which isn't perfect.

Has anyone tried the new clip yet? Are those three pieces all one needs to re-attach the button without glue and without disassembling the camera?

Flucard hacking / reverse engineering
Posted By tempelorg

Yes and yes. But an Eye-Fi card does not communicate with Pentax cameras. It only provides a file server to the files it has stored on its Flash drive.

So I don't think it'll help us in any way.

I ran into a more serious problem with the Flucard, though. I modified only the startup script a little by turning off the buzzer. I don't believe I've made any changes to the network (wireless) setup scripts. Yet, after these changes, even though the Linux system comes up fine, the http server on the card doesn't work any more - but the WLAN hotspot still works, ie. I can connec to the card's Wifi network and get an IP via DHCP assigned, but connecting to the web server times out.

I wonder if Pentax has added a second hacking protection level there, checking if the initramfs or parts of it have been messed with. After all, the "code" subdir of the firmware update for the Flucard contains some cryptic files, and one of them ("version") kind of looks as if it contains a MD5 or SHA checksum: 76 CA C9 9B 96 ED 9B 9E 30 60 B8 81 13 C5 0C 18 2E 60 C8 71 03 06 8B 18 30

The code inside "index.html" is also encoded or encrypted, no idea yet how.

The file "html", also part of the firmware updater, is an ELF executable that contains a reference to the "/code/version" file, so I guess I'd have to look there to see what this file is about. But not anytime soon, got some other things on my mind right now.

I have no idea how the Eye-Fi system works internally. It's not even clear if it uses a similar Linux setup. All the articles that talk about the Linux on the Flucard and Transcend cards never mentions that this is similar to Eye-Fi, so I doubt I can get into the Eye-Fi system as easily as into the Flucard. They're obviously not sharing the same setup.

What does your code show? Is that from the camera side again? The strings suggest that it's probably not. So, did you disassemble the busybux of the Flucard here or what are we looking at?

Fred, whatever you say. But that's besides the point. I like to keep the discussion on the original topic and not get sidetracked on policies, so please let's just drop this business about whether the card needs to be removed for service. It's an advice I've received but please let's get back on topic.

If both the screen and the phase-detection AF are out of focus, then it can't be the screen. So, Pentax would have no right to claim that the 3rd party screen could cause this. Plus, putting a screen in is not an unsanctioned hack either. But yes, I would not send in the camera with the KatzEye screen anyway, for the same reason I wouldn't include my SD Card or other non-essential parts.

JimmyDranox makes an interesting point. I do not agree with that, though, because if the secondary mirror would be out of line, then that would only affect the AF sensor but not the screen.

I just don't want to send in the camera right now if there's possibly an easy fix as I need it in 3 weeks and I have my doubts I'd get it back by then.

However, I have found a discussion thread, at dpreview, I believe, where someone quite familiar with Pentax repair manuals, claimed that it's rather normal that the mirror system ages and shifts over the years, and says that that's the reason why Pentax offers a tune-up and suggests to have the body serviced regularly (in 1-2 year intervals). He also explained that the body has active compensations depending on the temperature for that, too. The thread was about the K-10D, but I wonder if the same still applies, if it's true what he wrote.

I cannot find the thread again but I found this with a nice picture of showing the whole mirror + AF system in case someone here hasn't seen it yet:

Re: Badly aligned focus on K10D - tested!: Pentax SLR Talk Forum: Digital Photography Review

But at least I found the post I had in mind when I asked about making adjustments myself. See here:

RiceHigh's Pentax Blog: Hardware Adjust a Pentax DSLR for the AF

Still, I guess I'd need the K-3 service manual for that, and that's rather difficult to find.
