Ok, let me go take some photos with the noise reduction set on low.
But first, here are some additional photos using different types of live view AF. My E620 seems to be having issues with the AF sensor in live view though. Whenever I press the AEL/AFL putton on live view, the mirror flips really quickly but it does not focus. And yes, I did switch the settings in the menu to the AF sensor. So I have no idea what's up with that. So I focused using the viewfinder and then switched to live view, and pressed the AEL/AFL button again before taking each shot. That's my roundabout way of using the AF sensor in live view.
I also took some shots with the sharpness increased to +2
Then I took some shots with the 14-54(I) using the hybrid AF in live view (sharpness set back to zero). All other settings are the same as the originals except that the 14-54 is at 54mm, still f/7.1.
ISO100 +2 sharp
ISO200 +2 sharp
ISO400 +2 sharp
ISO800 +2 sharp
ISO1600 +2 sharp
