Hi and welcome!
To simplify my answer.....As long as your pictures are turning out ok, I suspect that nothing is wrong. Your camera needs to have the lens set at F22 to have correct metering as you use it. The meter has to base its readings off of the lens opening at the time of exposure....when you press the shutter release the camera automatically opens up the lens accordingly for proper exposure. It also opens the lens up for the maximum amount of light for you to be able to use the viewfinder effieciently.
How do you get the sharp photo with no background blur? Shoot at F11 or F16
Multiple focus points for group photo? I believe that if you shoot the P mode it will do that.
Enjoy your fine camera, you will be happy with it!
