Faulty A 350 ?

Hi there, this is my first post, and hopefully not the last, I do enjoy what I have seen and read here !
My question: But first a little background... I started photography on an old Pentax Spotmatic...great camera !
Next up was a Canon Powershot G5...once again another excellent camera...
I studied hard, took a lot of shots, and feel comfortable with the general principals involved (priorities etc.)
Now I own an A 350 with the 2 kit lenses, plus a 35mm 1.4 Minolta and a 135mm 2.8 Minolta... the latter are excellent lenses !
I am not getting consistently clear focused shots !
