can the Live View Mode substitute the MLP on the K1?

Mirror lock up

Guess so, it depends on how your composing the shot, in the viewfinder or on the screen as either way the mirror is up. If you wish to compose the shot in the viewfinder though it wouldn't really be alternative in practical terms.

I read somewhere that on several cameras there are still mechanical movements with the Live View. The mirror doesn't move, but the shutter curtains do?

On the K1 you can use MLU/Remote MLU using the viewfinder.

If you use Live View you cannot select MLU because the mirror is up already. Live view is a MLU capture, with both curtains in action.

You have a further option in Live view to use ES (electronic shutter) which uses electrical signals to start the exposure, and the second curtain to finish the exposure. The first curtain stays open for this.

The ES is the best mode to avoid mirror slap/shutter shock.

oh I see thanks. What do you think is the best then? Use the ES mode like you said (I didn't know that thanks) or switch to not LV after the composition and use the MLU?

I gather that MLU uses less battery power than LV but of course you are 'blind' for the process, so better for long exposures. I seem to recall reading somewhere that for long exposures with MLU you need to mask the eyepiece to prevent light leakage but that isn't required in LV.

yes I am aware of the light leakage issue, once it drove me so mad, since then I take the cap always with me.

Unquestionably use the ES. You are in LV mode anyway, so simply use the remote or press the shutter button (2 sec timer), and if your shutter speed is within the range that could induce shutter shock you are avoiding it completely.

I am assuming you are talking tripod shooting here.

I am possibly missing something here, but light leakage should affect all exposure methods the same .... normal shutter/MLU/Live View ? During the exposure the mirror is up and the first curtain is open.

As far as I understand you'll need firmware v1.30 or later to use the electronic shutter and enable it in the menu.

Correct John. I have added the ES icon to the control panel so it can quickly be set to on or off.

Among the limitations of ES are:
Shake Reduction is off and cannot be turned on (not really a problem as i cannot envisage using ES iunless it is on a tripod where SR should be off anyway.
Flash cannot be used.
