[Rick Tejada Flores]" In FCP settings do people recommend?"
When people talk about sharpening in post, they tend to be talking about doing this during the grade. The standard Sharpen filter in FCP is dreadful.
Whether and how much you sharpen all depends on the camera and lens combination used, as all will have slightly different degrees of sharpness even if the focus on-set is perfect. I find the GH2 to be quite sharp anyway, so use your judgement first before assuming a one-size-fits-all policy when it comes to sharpening.
