I have been doing some testing this weekend and the camera seems to output a lot of out of focus/missed focus shots. That's not quite what i were expecting.. the hitrate has been about 15-25% only which is pretty awful to be honest. Perhaps i need to spend more time with it and test it on different subjects in different situations with different settings than what i have done so far, but from what i can gather now it's sadly underperforming.
Start with clearing out the custom settings. What have you been shooting? To start with try shooting static stuff (flowers etc.) before moving to more challenging situations. There is a slight learning curve involved with this camera.
