If I understand the user modes correctly, the user mode is to set your camera to do certain things with out going into the menu to change to those certain setting every time you need those settings.
If you set the user mode to be Av and what ever F-stop you were using at the time of saving will be set in the memory.
Why it changes on your K5 and not use what is in the memory, I can't answer that, other then that might have been a small bug in the firmware.
My question is, why would you set user mode to act the same as a normal camera function?
I set the User mode identical to the Av mode as a test case. Normally (on both the K-5 and K-3) I set up a specific configuration, so that I can easily get back to a baseline after handling some "unusual" shooting situations. For the purposes of figuring out the difference between the -3 and -5 I wanted the User mode setting to be as similar to the Av mode to reduce/eliminate other variables.
By the way I applaud the change to three separate mode switch settings for the three User modes, versus the five menu options presented on the K-5... I often found that I would start adjusting the aperture setting before confirming the User mode with the "OK" button, resulting in an unintended change to one of the other User modes. That can't happen on the K-3.
