The thing you are running into is the bokeh or the falloff of the focus. At 1.8 it begins to get real precise as to where the range of focus is...you should try shooting with a 1.2 sometime

Yeah, that's lots o' fun... I have a 1.4 for the PZ1. Thought about the 1.2 but found the 1.4 used for 75.00. I use it indoors shooting available light at small concerts.
