Does the *istD manage SDM at all? I would assume then that a conversion wouldn't be possible with that camera.

All you are doing is to write to the lens. So the camera does not need to be SDM capable. The K100 and K110 can be used and they are not SDM capable.

Has anyone tried this with the *istD? If so any idea where the relevant files to loaded on the CF card can be found?

*istDS is not working - so I think *istD will not work, too - sorry!

Nope, Managed to get into the debug mode but no option on the menu to write the lens data.

Hello everyone!

After a lot of searching through the forms and help from dflorez, UncleVanya, and whoever made the dropbox link I was able to convert my lens. I had a hard time understanding the process, but I finally figured it out. I decided something this complicated needs a video. In this video I converted the 50-135mm lens, but I understand the process is the same for the 16-50, 60-250, 200, and 300mm lenses. I hope this is helpful to you and Good Luck!



The video is here: HOW TO: Convert SDM to ScrewDrive - Pentax - YouTube

Below you will see the process I followed. Again, I have the forums here to thank for giving me this information. I hope it helps you.




Too Much for you? Go here: https://www.pentaxforums.com/forums/24-photographic-equipment-sale/311609-sal...ersions-3.html

Wanna give it a try? Keep Going.

NOTE: I am not responsible for any damage that my occur to your equipment. Continue at your own risk.

Stuff you need:

Pktether: Since the site is down due to malware, here is a link to the most recent version on my Google Drive: https://drive.google.com/open?id=0B2uv9RXId6z4eUE2OTZmVTMybFk
If the site ever gets fixed... you can go here. BUT DON'T right now (05/24/16) PK_Tether – Tethering Software for Pentax DSLR Cameras
Nopad++ (text editor): Notepad++ v6.9.2
Pentax Forums Other Links:
https://www.pentaxforums.com/forums/10-pentax-slr-lens-discussion/208353-how-...-2-8-a-41.html


My Steps
1.) Download PKTether (pktether site)
2.) Download Camera Hack files (drop box)
3.) Download Notepad++
4.) Open Pktether
5.) Place SD card into camera, connect camera to computer (USB cable)
6.) Turn on Camera In PKtether activate DEBUG MODE
7.) Copy Hack Files to SD card
8.) Disconnect camera from USB cable
9.) Power Down Camera, Power back on
You are in Development Menu
10.) Scroll down to "Lens Rom Camera=SD" and hit OK. (it should go black, and then you will see the same screen again)
11.) Power off camera, Move SD card to PC and open it
12.) You are looking for the LENSEEP.LNS file. MAKE A BACKUP of this file - THIS IS LENS COPY SPECIFIC - ONLY YOUR FILE WORKS WITH YOUR LENS!
13.) Open LENSEEP.LNS with Notepad++
14.) Replace ALL instances of "C0" in column "03" with "80". DO NOT REPLACE any instances of "C0" outside of column "03".
15.) Move the new LENSEEP.LNS file to your SD card (replacing the orginal, remember to back up the orginal)
16.) Power Camera on
17.) Scroll to "LENS ROM DAT SD= CAMERA" and hit OK ( you will see "Wait..." and then some text)
NOTE: It failed the first time for me, needed to do it twice
18.) When Complete, lens should be in screw Drive
19.) Disable Debug Mode
A.) Use camera settings Menue Button Scroll left until you see "Test Mode" Disable Debug Mode Hit OK
B.) Connect to PKtether, Click Debug Mode Off
I am in the process of doing this on my DA* 50-135 2.8 with a k5 body. Is there pk tether, notepad + + available to my MAC OS X? I keep getting a box indicating that the program cannot run

Thanx in advance, would like an answer soon as I just bought the lens and have less than 2 weeks to return it due to af not working (assuming its a bad sdm motor). If I can diagnose it to screwdrive then ill end up keeping it since I bought it at a value price of $360 usd.

Do you have any older bodies? Did the sd card method for debug fail?

Thanks to the OP, sucessfully "screwdrived" my new to me 50-135 (SDM has failed, therefore it was only 160 € on ebay), workaround was done by K5 without pktether, just got into debug menu by copying files from dropbox to SD card.

Does anybody know if I can use a K200D for getting and saving the edited lensfile? I know a K10D can do but also a K200D?

As far as I know. I think you'd need an SD card with the file to enable the debug mode. How to access Debug Mode of Pentax K200 - PentaxForums.com

The K200 will be able to do it. Needs a slightly different file on the SD card to open the debug mode but otherwise, it works much the same as the K100.

Ok, thanks to you both. I have a DA 300 where the SDM seems to become capricious. I asked for a repair quote but I may go with a conversion and need a cheap body.

Conversion is a good plan. You can always sell the body later also.

In conclusion, the bodies that support SDM->screwdrive conversion in DEBUG mode are: K5, K5II, K01, K10, K100D, K200, K7, Kx.
