Originally posted by slr_neophyte I know about hitting the Info button in live view to be able to zoom in. This isn't exactly what I was trying to find. Before, I was sure I was able to press the shutter button down half way to engage auto focus (while in live view), and the camera would automatically zoom into whatever was in the centre of the frame so you could see fine focus adjustment.
This behavior was quite obvious on my K-r. In LiveView, the camera did #1-a digital zoom, #2-focused, then #3-returned to normal view.
I can come close, but not exact on my K-30 .... I have to set two menu options: AF Contrast needs to be set to 'Spot' and AF Autozoom set to 'on'. The behavior is still a bit different than my K-r. What then happens on my K-30 is #1-the lens focuses with a half-press of the shutter (you may have autofocus set up differently on your camera)., then #2-if you
hold the half-press position, LiveView will digitally zoom on the center.#3-After either taking the picture or releasing the button, LiveView returns to normal view.
During the digitally zoomed view, turning the rear wheel on the K-30 changes the amount of zoom. And, if you don't hold the half-press, rather focus and immediately release the shutter button, you will get a momentary zoom.
Note that I am also using focus peaking with LiveView on my k-30, and did not test if the above changes when this function is turned off. And, my AF/AE-L button is normally set to only lock exposure. I didn't take the time to test what happens if you use this button for AF purposes, but suspect it would make using the LiveView autozoom function much easier.
