K-01 software bug?

I was taking some pictures of the stars yesterday night in manual mode.

At one time I changed the ISO, then went to adjust time and aperture again. However, when I would change increase time, aperture was going down and vice versa.

It was like I were in Av mode when modifying aperture and Tv when modifying time. Is it a feature or some setting I missed? Or is it a bug in the software?

Were you in.. P mode? Because P allows shifting like that, where it keeps the same exposure, but it changes shutter and aperture (one up, one down).
M mode shouldn't change anything automatically - UNLESS you use green button, or turn on Auto ISO (with a manual lens mounted, M mode with auto ISO will default to Av mode, with modern lens it will default to TAv mode)

I suggest you charge up your battery, leave it outside camera for a couple hours, and then update the firmware or reset to factory defaults. See if it ever happens again.
I have never seen this behaviour with my K-01, and I use M mode often - but usually with manual lenses.

I should have added that I turned the camera off, then back on and the feature had disappeared.

To answer your questions, I was in M mode and did not touch the green button. But now I have a doubt in my mind...what if I inadvertently touched it?

Is this green button "on" until it's turned off again?

ISO was initially on 1600 and when I changed it to 3200 it started behaving strangely.

mamethot: I don't see that behavior. I'm on FW 1.04, testing with a Sigma Super-Wide II 24mm F/2.8 MF lens in "A" position... What firmware are you on and which lens are you using?

Using a Tamron 16-50 2.8, firmware 1.04.

As stated previously, I cycled the camera and the behavior disappeared.

Well, all's well that ends well, I guess. For me green button in M mode (with an "A" lens), sets the shutter speed for appropriate exposure, unless I'm also in Auto-ISO, in which case both the iso value and the shutter speed are modified by hitting the green button. (If you are in M and Auto-ISO mode, you'll see "TAv" appear in the upper-left of the LCD, and the ISO will always vary when changing either the shutter or the aperture.)
