This plant was just beginning to bloom and the flowers that had emerged were not fully developed, but the buds were very nice. I focus stacked a few shots to capture most of the buds in focus.

Scratched viewfinder K100D
Posted By Gerbermiester

Hello all,

I thought I'd add some more info to a thread that just won't die!

I recently bought an old k100d with a scratched up viewfinder to use as a second body at wedding shoots. Lo' and behold, when it arrives on my doorstep and I take a peek through the viewfinder it is indeed scratched, and scratched badly. I was expecting the scratches to appear as little lines visible when I looked through, however, looking through the viewfinder, all I could see was a foggy blur. (So foggy, in fact, the camera could only be considered inoperable).

Well, crap.

I contacted Pentax Canada in search for replacement parts. They replied as follows:

"If you plan to install if yourself, the part nbr. is 0076570 L7, eyepiece rear lens, cost $16.46 ea.,
plus s/h $10(Fedex) plus applicable taxes. We have stock on hand."

Great! I thought, until I looked up the service manual for the camera online, which outlined how to replace the part. It's a big job. I would have needed to remove several pieces of the camera's body to get access to the viewfinder, and in some cases, would have had to de-soldered wires. A bit risky for my taste. I've heard that other Pentax bodies permit easier access to replace the viewfinder, but sadly, not the K100d.

Well, crap again.

After reading a few other reviews online, I decided to polish the glass instead and hope for the best. The only product that I had heard a first-hand report with positive reviews was a product called Novus Plastic Polish #2. I ended up ordering it, half expecting that I'd need to replace the viewfinder anyway (the viewfinder was really really scratched up). But for $7 Canadian, why not take a shot on the plastic polish first?

It worked. Perfectly. It didn't make the viewfinder better, it made it like new. I was flabbergasted.

If you have a scratched up viewfinder, buy Novus Plastic Polish #2. It is an amazing product.

Here is how I polished my viewfinder:
1) I took out five or six cotton swabs (the kind you might use to clean your ears) and set them down on a clean surface.
2) I took my air blower bulb and blasted out any dirt that might have still been on the viewfinder.
3) I placed a small amount on polish (about the size of half a green pea) upon the cotton swab's head.
4) I very gently rubbed the polish left and right, then up and down on the viewfinder screen.
5) I wiped away the polish from the viewfinder with the clean side of the cotton swab.
6) I took a new swab and put some polish on that one too.
7) I rubbed to polish in small circles all around the viewfinder, again, very gently.
8) I wiped off the excess left on the viewfinder with a clean cotton swab.

And thus my viewfinder was fixed.

I'm still baffled over how well it worked.

K200D autofocus fine tuning.

Holy-sh*t-house-mouse, it works. AF adjust on the K200D.

Noticed some significant front focusing with my new Sigma 30 f1.4. A bunch of my pics from our friends Halloween party were OOF, but a few accidental shots were dead sharp, so I new it was just calibration. Ran the above commands but accidentally set it to -120 first time and WOW what a difference. Retested & trimmed that back to -50 and I think I'm good. Need to do some field testing next time I go to the pub for some low light portraits but after a few days of researching I'm happy this actually works :D:D.

Notes for newbs running PCs, as I'm a complete newb and this took a few tries to figured it out :o

1. Completely unscientific calibration test
I just used the Pentax quick reference guide as a testing plane instead of buying a thermometer like some others have suggested. Opened to a page with a bunch of text but with a line or two of open space in the middle. Wrote "FOCUS" with a Sharpie in the empty space with some cross hash marks to the left and right. Had the camera on Gorillapod about 6 inches high and the focal point about 2 feet from the end of the lens.

Make sure you're on single point center focus and the widest aperture you've got. Snap a few pics and see if the "FOCUS" and hash marks are in the center of the in-focus area of the picture. Before adjusting mine, it seemed that the "FOCUS" was blurry but a few lines of text in front of it were tack sharp = front focus (the actual in-focus zone is in front of where the camera thinks it is).

After making adjustments, I'd walk around the room shooting things that would obviously show FF/BF to check my calibrations. Few pieces of Halloween candy on my kitchen table at slightly different distances was a good test. Also tried shooting close to (within 5 feet) and further (across the room about 10 feet). Repeat the test and the steps below few times until it's satisfactory.

2. How to make Text File
Insert the SD Card & Reader into your computers USB and open a window for the SD Card through My Computer (mine was "Removable Disc H:"). Right click over the empty space on the right side of the window, which brings up a menu. Scroll mouse down to "New" which brings up another menu and towards the bottom is Text File (or Text Document for me in Vista). Click Text Document and badda-bing, you've got a fresh Text Doc.

3. How to edit Text File / Text Document
The new Text Doc will be named "New Text Document.txt". Open & Edit the text document before renaming it! Open up the Text Doc and type in exactly [DEBUG_MODE EN]. Close & save (automatically prompts you to save in Vista). Right click the Text Doc icon and rename to "MODSET.445" (no .txt at the end). A warning will probably pop up asking if you're sure you want to continue - click yes.

4. How to run Debug mode
Enter the card back into the cameras SD slot, but do not close the door. Hold down the Menu button and turn the camera on. It should display two version numbers (mine were both 1.00.00.02), the screen dimly flickered a few times, then everything shuts off... scared the crap out of me the first time :confused:! Turn the power switch back to OFF and shut the card slot door. Your camera is now off but in DEBUG mode.

5. How to find and adjust AF Adjust
Turn the Power Switch back on (no need to hold Menu). The screen will flicker a little, then just show a blank dark glow. Press MENU - brings up the menu screen which looks pretty normal. If you scroll through all of the tabs, you'll notice some extra adjustments that aren't normally there...sneaky! Click the Right Button twice to highlight the Setup tab. Press Up Button twice (or Down Button a bunch of times) to reach "AF TEST", then click Right Button to open the AF TEST screen. First is AF Area Test with options of 0,1,2,3. I just left it on 0, not really sure what this one does. Click the Down Button to highlight "Focus Corr" to correct the focus. Left for Front Focus and right for Back Focus. Try going +/- 50 or 60 to start with and test/retest a few times from there. Press OK and you're done adjusting (at least this round), and turn the Power Switch back off.

6. Exit Debug mode back to normal operating mode
Right now, your camera is still in Debug mode so every time you turn it on, it will still be in Debug mode and you can't take pictures. Take out the SD Card, pop it back in the computer and open up the SD Card Window. Rename the "MODSET.445" Text Document to "MODSET.445.txt" (and click YES if the warning pops up again). Then open the Text Doc, delete the previous text and enter exactly [DEBUG_MODE DIS]. Close & save, then remember to rename the Text Doc again, back to "MODSET.445" (no .txt at the end). Plug the card back in the cameras SD slot, leave door open, hold menu & turn on. The screen will flicker, show those two version numbers and then go blank again. Turn the Power Switch off. You're out of Debug mode and back to normal.

However I would go ahead and remove that text file, not sure if its the best idea to leave them on the card but that's just a guess. Might be a good idea to buy two tiny SD cards, one with Debug Enable and the other with Debug Disable prompts on them, so you could adjust in the field without a computer ;)?!? Each file is only 16 Bytes...hahah.

Try this at your own risk, but I hope this detailed account of my experience helps.

K100d super k100ds debug mode - AF adjust
Posted By Lititz

Here and on other sites I've seen information on accessing the K100d Super debug mode (for focus calibration) that isn't always clear or consistent. For example, sometimes it says to use the EN (enable) command in the MODSET.459 command file, other times to use the OPEN command, sometimes both, and I've seen different comments about how to exit debug. Can any K100d Super users clarify for me, step by step, what works for them in doing this (how to enter debug, get to AF calibration, and then exit debug). I'm reasonably comfortable doing this kind of manipulation (having done it before on K100d not-super). Thanks very much.
