If you're in Aperture Priority (AV) when you auto-bracket it should keep
the aperture constant and change the shutter speed.
I've never had to resort to the green button to get it to do that on the
K20D & I don't see Pentax making such a radical change on later models.

Thanks Brian
I manged to change mine after a couple of attempts. It is far from
intuitive.
As a default I prefer keeping a constant aperture, especially for
shooting HDR sets

I got caught out when shooting some panos recently, bracketing in
manual mode my camera would default to bracketing Tv so the aperture

Just in case you were not aware the remedy to change the bracketing to
Av lies in the "green button" setting of the E-dial programming
whether you have the "green button" active or not. To change it go to
the E-Dial Programming menu for manual and select "TvShift". I found
the solution on-line, the manual was next to useless.
I've read this twice and I can't figure out what you're talking about.
Mind expanding/explaining?
Allow me.
I played around with my K5 after reading Rob's post and I think I
understand what he's getting at.
If you have the camera on Manual Exposure and fire off a bracket of
(say) three images, the camera will hold the shutter speed constant and
change the aperture for each exposure.
What Rob wanted was to hold the aperture constant and allow the shutter
speed to change with each exposure.
As he said, you can accomplish this by going to Rec Mode Settings menu
5, selecting 'E-Dial Programming Menu 2' and changing the Green Button
setting for 'M' to Tv Shift. Page 284 of the manual shows the available
settings, but their use is far from intuitive.
