K-X sr working?

Does your K-X make a whirring sound when sr is on?
Here is why I ask.
In live view, if sr is on, I here a whirring, busy noise coming from the camera. With SR off I do not.

When NOT in live view, I never hear that whirring noise, whether SR is on or off.

So is SR NOT working in "non-live view" mode? Do you ever hear that whirring sound coming from your camera when not using live view?

BTW, I get the green hand and all, and body is set to manual focus to eliminate lens focus noise. and NO sounds from the camera, SR on or off.
Thanks.

Manual focus means that you might be skipping the "half-press" phase of shooting that most people do, which looks like this:

half-press while focusing, then full-press to shoot.

When you half-press, it takes about a second for the SR to enable. The green hand shows up in the viewfinder a little bit after you half-press. If you shoot before the green hand, then you won't get SR. If you wait until the green hand shows up, then you should get SR.

I think (but I don't know) that you might not half-press at all, because you are focusing manually. If so, then SR wouldn't turn on.

In live view the sr is on all the time correcting for any movements...

In photo mode it really only kicks in when you half press the shutter...

Thanks for the reply Aegon. Yes, I've tried with AF on and off. And I do wait for the green hand.

So I guess my simplest of questions to you guys is this.

Does your K-X make a whirring sound when sr is on but not in live view?
and
Does your K-X make a whirring sound when sr is on in live view?
and
Does your K-X make a whirring sound when sr is off in live view?

Thanks..

I can't answer the K-X stuff, but here's something else to try.

Use manual mode or Tv mode to set a long exposure time. Then shoot and listen. You should hear the whirring on a 10 second exposure.

Igilligan, that's what I thought and fully expected to hear it when the shutter was half pressed, but I do not.
Aegon, I just tried that and you are correct. I do hear it whirring on loooong exposures AFTER the shutter button is fully pressed but before the shutter closes again.
Interesting.
Thanks all for the responses.

The sensor don't start moving until the button is fully pressed, that is why you will not hear the SR-motors during half-press.
