I've been reading some articles recently on landscape photography, and the same tip keeps coming up 'MLU'. I have checked my Camera Manual and nowhere (other than senser cleaning) does the mention of muirror lock up appear.
I've also googled MLU for K30 and the only reference is when using liveview, but then says that is no good because the mirror closes then opens raises agian to take the image. I've recently been looking at "digital preview" display and was wondering if the mirror closes and opens again when taking an image using this option.

Thanks
