Just been out shooting auroras with my K-3. It was constant struggle. It kept changing shutter speed and/or aperture constantly in Manual(M) mode. Sometimes (more often than not) I was not allowed to choose a certain apertures (like larger than F:4 ) and/or not allowed to choose shutter speeds longer than 20s (30s is max manual shutter speed). After I had shot an image the camera would have changed shutter speed and/or aperture for the next exposure. I thought the whole idea with manual mode is that you set the shutter speed/aperture combination you want and that's it until you change it.
Have to use Bulb mode and the watch.
Is there some sort of weird custom function (can't find it) that cause this behaviour or is the camera bonkers?
Shot this 1.5 hours ago (and plenty of others)....
Pentax K-3 + DA* 11-18/2.8, at 11mm F.2.8, 30s 800ISO
(The rather unfortunate red light at right corner is the landing light for the airport, It is behind a hill and not visible to me but it obviously light up the landscape surrounding it)
