Odd shutter speed issue?

I've only just started to notice this issue with my K-30 and the 1.06 firmware. When I shoot, it has started to jack up the shutter speed (just now it went from 1/60 to 1/500 without any input, then back to 1/60 the next shot)

Is this a bug, or am I just missing something?

Are you using the flash?

No... I just noticed the issue... It was set to do the exposure bracketing thing, but I saw it as the continuous mode. (My go-to) I'm blind.

It's in Manual mode. I figured out that it was set to bracket exposures, but now I'm confused, as I thought exposure bracketing set the shutter speed to 3 different values, rather than switching between two... Hmm....

I don't believe that's correct. On my K-30, with camera set to M mode, bracketing doesn't change the shutter speed at all. It takes three shots, each at a different EV value but shutter speed remains the same for all three shots.

I'm not sure. I'll have to test when I get home. (I'm out with a film body today.)

I'll have test more thoroughly, as I found it strange, only getting two shutter speeds.

how can the ev change when everything remains the same?For instance in M mode if u set ur bracketing to start with a correct exposure then underexpose and then overexpose, the camera needs to adjust both aperture and shutter speed in order to do so for the 2nd and 3rd exposure....so i doubt they stay the same

As for the problem you have SpartanD63 also have a look at the EXIF info just to make sure that the shot was taken in M mode depsite what your camera is telling you.just in case the dial might be playing up

I didn't see any change in shutter speed on the ones I checked through EXIFtool, but of each bracketed shot one was underexposed, one was normal, and one was overexposed. Still none had a change in shutter speed. So, I am not entirely sure how bracketing works in what all changes for each shot.

I went back and checked each shot and the camera did change shutter speed and aperture for each bracketed shot. I just never noticed it before.

Do you have your ISO set to auto instead of you changing it? Mine is always set so I can choose which ISO I want to start out with, then the camera changes it as it sees fit.

Mine's always set manually. And now that I'm home, I can't seem to repeat the issue. Perhaps I was inadvertently hitting something to reset the bracketing back to the original value? I'll keep toying with it.
In any case, it seems to be working as it should now...
