Auto Bracketing with constant aperture?

Auto-bracketing, particularly for panorama photography, absolutely requires a fixed aperture for all exposures within the bracket range.. Not too long ago, I found a post on how to set a custom function in the K7 menu that locks any preset aperture in manual mode while using auto-bracketing. Unfortunately, I didn't note its location within Pentax Forums. Haven't been able to use the right search terms this evening.

So, with the K01, is it possible to lock the aperture at a pre-set value and use the camera's auto-bracketing feature? I am really not looking forward to setting every single exposure manually. If so, how?

When I auto-bracket with the K-5 in aperture priority mode, the camera varies shutter speed and keep the aperture I set. I do not believe I changed settings to make it so.

Av = fixed aperture
Tv = fixed shutter
ISO in this setting can change if set to auto

That is the easiest or you can setup M mode to your way.

Might one of these be the thread that you would be looking for?For the most part I just shoot in Av or M mode - usually with a manual lens - setting the aperture ring.
