Yes.

What I do, however, is to save threads as 'Favourites' in my browser.

Within 'Favourites' I have a number of folders, sub-folders, etc, in which I save links to threads, sites, etc. There's a facility to rename the saved link to something more descriptive.

So, as an example, I have a folder called 'Photography', in which there's a sub-folder called 'AF Adjustment', which contains links to dozens of helpful threads, articles, etc, covering that subject (not just Pentax related) from all over the web.

I use IE9, but all browsers have this facility.

"The Pentax K-5 II is a remarkable piece of kit, it scores better in the DxO mark tests than several very highly thought of, full frame DSLRs, beating all the cameras made by Canon! It manages to do this in a body that is very reasonably priced. Add to this that you can fit lenses to the K-5 II that Pentax made as far back as 1975 and the multitude of independent lenses that are available and this camera becomes not only a remarkable performer but also a fantastically versatile camera at an exceptional price."

Check the outbox. PM's are only sent when the addressee is on line, otherwise they sit in your outbox.

Try cleaning the contacts on the mount, and just inside the mouth of the mount, with a dry, clean, lint free cloth.

These contacts carry various information to the body. Could be a dirty contact might be the issue, and if it's not it's quick and trouble free to check.

Do you mean your lenses on another K5?

What happens if you focus manually?

I was going to ask the same thing

FWDC215B.BIN appears to be the correct file. You are copying it to the root of the SD card and not into a DCIM folder?

I'd download the file again from Pentax and extract the .bin file once more, just in case it got corrupted somehow.

Format an SD card (2gb or greater) in the camera, transfer the card to your PC/laptop, copy the .bin file across to the card, transfer the card back to the camera then follow the instructions I've already posted.

You have extracted the file to the root of the SD card (and not just copied it over as a zip file?)

Updating Procedure
[1] Provide a formatted SD memory card for the update software.
The download file is self-extracting. The following file is extracted. •Fwdc215b.bin: This is the updated firmware.
Copy the above Firmware file [fwdc215b.bin] to the root directory in the SD card.
If your computer does not have a card slot, you can copy the firmware update file by inserting the SD card into your camera and then connecting the camera directly to your computer.

[2]Insert the the D-LI109 battery into the camera and confirm the battery is full by battery level indicator then turn the camera off.
[3] Insert the update SD card (prepared in step 1) into the camera and close card cover.
[4] Turn the camera power on.
[5] Press MENU button to display MENU screen.
[6] Press the four-way controller right to display [Set-up 3] menu screen.
[7] Select [Firmware Info /Options] in the [Set-up 3] menu then press the four-way controller right.
The firmware version for the camera and lens are displayed on the [Firmware Info/Options] screen.
[8] Press the four-way controller right to display update screen.
Press the four-way controller up to select [Start] and press OK button.
*If firmware file is not saved to SD card correctly, this screen will not be displayed.
[9] Card access lamp will be blinked and display will be changed from [NOW LODING] to [COMPLETE].
*Do not turn OFF the camera while updating.
[10] Automatically turn OFF the camera. (Approx. 5 second)
[11] Remove the SD card from camera.
*Confirm the version of firmware with above [How to check version].
[Caution]
When updating is finished, the update SD card still contains the Firmware file.
If you want to use this card to take pictures, format the card by the camera to delete firmware file first.

I would expect to agree with you, but it appears that the lens, scene and lighting are common, so the only change is the body, the suggestion being that the AA filter seems involved in the production of PF.

Returning to the thread in question, (link), a few more views have been posted, suggesting there's a little more to the IIs than first thought, in addition to this alleged reduction in PF, i.e. that it's SR is good for an additional stop, although it's not clear whether this is against the K-5 'Classic' or II.
